Fakemeta function:
EngFunc_PointContents

Description:
This function checks an origin and gives us information of its whearabouts.

The constants that this function returns are these:
#define CONTENTS_EMPTY -1
#define CONTENTS_SOLID -2
#define CONTENTS_WATER -3
#define CONTENTS_SLIME -4
#define CONTENTS_LAVA -5
#define CONTENTS_SKY -6
#define CONTENTS_ORIGIN -7 // Removed at csg time
#define CONTENTS_CLIP -8 // Changed to contents_solid
#define CONTENTS_CURRENT_0 -9
#define CONTENTS_CURRENT_90 -10
#define CONTENTS_CURRENT_180 -11
#define CONTENTS_CURRENT_270 -12
#define CONTENTS_CURRENT_UP -13
#define CONTENTS_CURRENT_DOWN -14
#define CONTENTS_TRANSLUCENT -15
#define CONTENTS_LADDER -16
#define CONTENT_FLYFIELD -17
#define CONTENT_GRAVITY_FLYFIELD -18
#define CONTENT_FOG -19

Usage:
static Float:origin[3]
static result
result = engfunc(EngFunc_PointContents, origin)
// if for example result is CONTENTS_SKY
// then the origin that we see is in the sky we can for example use this to see where a player is aming if he is aiming at sky this will be the result!

( Nice initiative but I think it should be update on the wiki too because more readable. Also for here creating a list for fakemeta and ham would be interesting. )

[joaquimandrade]

Nice ot.

I think that we should update here first and after that do a wiki. :)
And thanks!

Nice ot.

Thanks! If you have functions or constants that are important please post :).

Fakemeta function:
EngFunc_TraceLine

Description:
This function traces between 2 origins and gives us information about it.

The constants that we can use in flags:
#define DONT_IGNORE_MONSTERS 0
#define IGNORE_MONSTERS 1
#define IGNORE_MISSILE 2
#define IGNORE_GLASS 0x100

These constants can be used together.
Ex: IGNORE_MISSILE | IGNORE_MONSTERS | IGNORE_GLASS - This makes the traceline ignore missiles, monsters (players) and glass.

Here is a drawing that will show you how it works!
engfunc(EngFunc_TraceLine, start, end, IGNORE_GLASS, 0, tr)
http://img529.**************/img529/1863/traceline1.jpg (http://img529.**************/my.php?image=traceline1.jpg)

engfunc(EngFunc_TraceLine, start, end, DONT_IGNORE_MONSTERS, 0, tr)
http://img529.**************/img529/1415/traceline2.jpg (http://img529.**************/my.php?image=traceline2.jpg)

engfunc(EngFunc_TraceLine, start, end, IGNORE_GLASS, 0, tr)
http://img529.**************/img529/5815/traceline3.jpg (http://img529.**************/my.php?image=traceline3.jpg)

engfunc(EngFunc_TraceLine, start, end, IGNORE_GLASS, 0, tr)
http://img529.**************/img529/326/traceline4.jpg (http://img529.**************/my.php?image=traceline4.jpg)

Functions that come with the TraceLine pack:
// Description: This creates a trace handle!
// It is important to use because we don't want our plugins to mess with eachothers info!
new ptr = create_tr2()

// Description: This creates a trace handle!
// It is important to use because we don't want our plugins to mess with each others info!
free_tr2(ptr)

// Description: Gets/Sets information from/in the trace_handle
[g|s]et_tr2(trace_handle, CONSTANT, number_if_needed!)

CONSTANT Expresion has this posible values:

enum TraceResult
{
TR_AllSolid, // int
TR_StartSolid, // int
TR_InOpen, // int
TR_InWater, // int
TR_flFraction, // float
TR_vecEndPos, // float array[3]
TR_flPlaneDist, // float
TR_vecPlaneNormal, // float array[3]
TR_pHit, // int (edict_t*)
TR_iHitgroup, // int
};
The float and array values need the third argument! Example:

new allsolid = get_tr2(trace, TR_AllSolid)
new startsolid = get_tr2(trace, TR_StartSolid)
// TR_StartSolid is a boolean that says whether you were "inside" something
// (usually the world) when the trace started (point A)
// TR_AllSolid tells you if you ever got out of the "inside" or not.

new inopen = get_tr2(trace, TR_InOpen)
// TR_InOpen means that the start point is in Open
// That means in the world and not in an ent or something

new hit = get_tr2(trace, TR_pHit)
// What was hit by the traceline. It will either be a player index,
// entity index, 0 (part of map), or -1 (didn't hit anything;
// doesn't happen with player tracelines).

new hitgroup = get_tr2(trace, TR_iHitgroup)
// If the traceline hit another player, returns will be HIT_HEAD,
// HIT_CHEST, HIT_LEFTLEG... etc. If the traceline hit part of the
// map, this returns HIT_GENERIC.

new Float:fraction
get_tr2(trace, TR_flFraction, fraction)
// Returns a number between 0.0 and 1.0, indicating how far the
// traceline traveled start to end before it hit something. Depending
// on what conditions were passed to this traceline forward function,
// it could either be a wall or another entity.

new Float:end_origin[3]
get_tr2(trace, TR_vecEndPos, end_origin)
// The official end of the traceline. Not necesarily the same as the
// second argument passed to this traceline forward function.

new Float:normal[3]
get_tr2(trace, TR_vecPlaneNormal, normal)
// Returns a 1 unit long vector normal to the spot that it hit. Note
// that "normal" has a special connotation here. It doesn't mean "regular."

Example Stock:
stock is_wall_between_points(Float:start[3], Float:end[3], ignore_ent)
{
// Create the trace handle! It is best to create it!
new ptr = create_tr2()

// The main traceline function!
// This function ignores GLASS, MISSILE and MONSTERS!
// Here is an example of how you should combine all the flags!
engfunc(EngFunc_TraceLine, start, end, IGNORE_GLASS | IGNORE_MONSTERS | IGNORE_MISSILE, ignore_ent, ptr)

// We are interested in the fraction parameter
new fraction
get_tr2(ptr, TR_flFraction, fraction)

// Free the trace handle (don't forget to do this!)
free_tr2(ptr)

// If = 1.0 then it didn't hit anything!
return (fraction != 1.0)
}

Fakemeta function:
EngFunc_FindEntityInSphere

Description:
Find entities within a radius. The function returnes the next entity id after the start entity!

This is a drawing to show how this function works:
http://img265.**************/img265/2395/screenshot053.png (http://img265.**************/my.php?image=screenshot053.png)


If we use
engfunc(EngFunc_FindEntityInSphere, -1, origin, radius)
The function in the situation above will return 1!
engfunc(EngFunc_FindEntityInSphere, 20, origin, radius)
The function in the situation above will return 30!
engfunc(EngFunc_FindEntityInSphere, 100, origin, radius)
The function in the situation above will return 0, meaning that it didn't find an entity with an id grater than 100!


Usage:
engfunc(EngFunc_FindEntityInSphere, ent_to_start, origin, radius)

But you should also try to describe some functions or constants. I can't just do all of them...

[Arkshine]

Good idea.

I was my suggestion above. I haven spoken chinese probably. :mrgreen:
I will try to describe some functions too.

I can't just do all of them...

I'm sure you can. :p

Fakemeta function :

EngFunc_PrecacheModel


Description :

Precaches a model or sprite file.

This should be used only when you would need to postpone the precache processus in plugin_init() (http://www.amxmodx.org/funcwiki.php?search=plugin_init&go=search) or plugin_cfg() (http://www.amxmodx.org/funcwiki.php?search=plugin_cfg&go=search), otherwise you should use precache_model() (http://www.amxmodx.org/funcwiki.php?go=func&id=15) native directly in plugin_precache() (http://www.amxmodx.org/funcwiki.php?go=func&id=7) forward.
It can be useful for example when you want to manage models with cvars and to avoid registering them in plugin_precache() then getting some trouble, you could manage out of this forward.

Usage :

engfunc( EngFunc_PrecacheModel, "models/MyModel.mdl" );
engfunc( EngFunc_PrecacheModel, "sprites/MySprite.spr" );

It returns the precached model/sprite index if successful, otherwise 0.

[Arkshine]

Fakemeta function :

EngFunc_PrecacheSound


Description :

Precaches a sound, only *.wav file. ( for mp3, see EngFunc_PrecacheGeneric )

This should be used only when you would need to postpone the precache processus in plugin_init() (http://www.amxmodx.org/funcwiki.php?search=plugin_init&go=search) or plugin_cfg() (http://www.amxmodx.org/funcwiki.php?search=plugin_cfg&go=search), otherwise you should use precache_sound() (http://www.amxmodx.org/funcwiki.php?search=precache_sound&go=search) native directly in plugin_precache() (http://www.amxmodx.org/funcwiki.php?go=func&id=7) forward.
It can be useful for example when you want to manage sounds with cvars and to avoid registering them in plugin_precache() then getting some trouble, you could manage out of this forward.

Usage :

engfunc( EngFunc_PrecacheSound, "sound/MySound.wav" );

It returns the precached sound index if successful, otherwise 0.

better create some kind of wiki where everyone can contribute like wikipedia, would be more handy than a forum thread.
i would appreciate that very much :D

Fakemeta Function:

EngFunc_MessageBegin

Description:

This function is used to generate client messages.

Usage:

engfunc(EngFunc_MessageBegin,dest,msg_type,or igin[3]={0,0,0},player=0)


static Float:origin[3] // Origin should be a Float
pev(id, pev_origin, origin) // Get user origin
engfunc(EngFunc_MessageBegin,MSG_BROADCAST,SV C_TEMPENTITY,origin,0) // Create message

//With MSG_ONE_UNRELIABLE
engfunc(EngFunc_MessageBegin,MSG_ONE_UNRELIAB LE,SVC_TEMPENTITY,_,id) // Create message

//With MSG_ALL
engfunc(EngFunc_MessageBegin,MSG_ONE_UNRELIAB LE,SVC_TEMPENTITY,_,id) // Create message
dest can be :


#define MSG_BROADCAST 0 // Unreliable to all, There is not id
#define MSG_ONE 1 // Reliable to one (msg_entity)
#define MSG_ALL 2 // Reliable to all, There is not origin
#define MSG_INIT 3 // Write to the init string
#define MSG_PVS 4 // Ents in PVS of org
#define MSG_PAS 5 // Ents in PAS of org
#define MSG_PVS_R 6 // Reliable to PVS
#define MSG_PAS_R 7 // Reliable to PAS
#define MSG_ONE_UNRELIABLE 8 // Send to one client, but don't put in reliable stream, put in unreliable datagram (could be dropped), There is not origin
#define MSG_SPEC 9 // Sends to all spectator proxies
Before calling another EngFunc_MessageBegin you must call message_end()

[Arkshine]

Your example is wrong. There is not id nor origin for MSG_ALL/MSG_BROADCAST. You should add an example for all.

[Starsailor]

oo yes, you are right, i have forgotten that

EDIT: Done

[ConnorMcLeod]

Your example is wrong. There is not id nor origin for MSG_ALL/MSG_BROADCAST. You should add an example for all.

+ origins have to be floats.

[Arkshine]

oo yes, you are right, i have forgotten that

EDIT: Done

It's still wrong.


engfunc( EngFunc_MessageBegin, MSG_BROADCAST, SVC_TEMPENTITY );
engfunc( EngFunc_MessageBegin, MSG_ALL, SVC_TEMPENTITY );

engfunc( EngFunc_MessageBegin, MSG_ONE_UNRELIABLE, SVC_TEMPENTITY, _, id );
engfunc( EngFunc_MessageBegin, MSG_ONE, SVC_TEMPENTITY, _, id );

engfunc( EngFunc_MessageBegin, MSG_PVS, SVC_TEMPENTITY, origin, 0 );
engfunc( EngFunc_MessageBegin, MSG_PAS, SVC_TEMPENTITY, origin, 0 );

You should also comment more each MSG_*.

[SchlumPF*]

EngFunc_Message_Beginuses floats, message_begin() doesnt.
if you explain such a function you should add an example when to use EngFunc_Message_Beginand when to use message_begin() because imo is EngFunc_Message_Beginkinda unnecesarry :X
also, you should explain MSG_INIT, PVS and PAS (with a short example ofc). at least because i never was able to find that out xD i mean MSG_ONE and MSG_ALL (+ the unreliable ones of them) are quite common but i guess there are a lot who never used MSG_INIT, MSG_PVS and MSG_PAS.
another thing is the origin, are there a few messages where you need it? i mean most messages need write_coord() to set the origin ^^

[Arkshine]

EngFunc_MessageBegin is not unnecessary if you work with float and you use MSG_PVS/MSG_PAS. But it's true except that, message_begin() (http://www.amxmodx.org/funcwiki.php?go=func&id=262) should be used.

Btw :

MSG_PVS = Potentially Visible Set = The message will be sent only to player who potentially view the provided origin.
MSG_PAS = Potentially Audible Set = The message will be sent only to player who potentially hear the sound from the provided origin.

It's useful to reduce data sent to a client.

MSG_PVS_R and MSG_PAS_R are not used. I think there is a thread about that.

[Exolent[jNr]]

This is the most unorganized information tutorial I've ever seen.

That's why it's better to use directly the wiki. :p

It is good that you are trying to help and you should also receive :crab:'s for that but you must help correctly! Look at the way I did the functions :), if you can do the same it will be great, arkshine is lending you a hand :wink:, try to take into account his advices.

It is good that you are trying to help and you should also receive Karma for that but you must help correctly! Look at the way I did the functions :), if you can do the same it will be great, arkshine is lending you a hand :wink:, try to take into account his advices.
there is no karma anymore, you need to give :crab:'s now :D

[ot_207]

Right! Fixed that :mrgreen:!
Ja! Ich habe das repariert :mrgreen:!

Edit: Wo hat diese geniale idee, um Krabs stattdessen Karma geben?
Who had the idea of giving crabs instead of karma?

Edit2: SnoW the thread is already spammed enough so one post in plus won't make a dif :P.

[SnoW]

Who had the idea of giving crabs instead of karma?
You are making spam to your own thread. It was never instead. Guys gave crabs much before the karma system was nuked.

[SchlumPF*]

Edit: Wo hat diese geniale idee, um Krabs stattdessen Karma geben?
Who had the idea of giving crabs instead of karma?

Wo = where, who = wer
-> Wer hatte diese geniale Idee (there is no "genial" in your english sentence), Krabben statt Karma zu geben. (falscher Nebensatz).

i love ppl speaking german who learned it barely :D the sentences are most often wrong but you can understand nearly each sentece... this is much harder if someone _tries_ to speak english xD

:crab::crab::crab: to you ot_2007 <3

ot:
as you can see a thread is a really bad assembly of this idea which is really nice. some kind of wikipedia including a thread here at amxx where ppl can complain about erros and give you -:crab:'s!!!

[ot_207]

Let's create a wiki with this. These functions will be useful.

[SnoW]

Oi but you need a name on that. The thread's name is too long i guess.

HamSandWich function:
Ham_TraceAttack

Description:
Forward: This function is called when an entity is shot by another player (weapon, not grenade.)
Function: This function simulates a weapon attack on an entity.
You should use this function when you want to simulate an attack by a weapon from a player (like a gunshot!)

Parameters:
(ent, attacker, float:damage, Float:direction[3], trace, bits)
- ent is the entity that has been shot
- attacker is the entity that shoot the victim
- damage - this is the damage done by the shot but it does not have the hitgroup multiplication done (that is done before TakeDamage Call)
- direction - this parameter has a very important roll, it is a normalized vector that shows the direction of the bullets path
- trace - the trace handle that offers lots of useful information
- bits - the damage bits

Forward usage:
#define SHOT_DISTANCE_POSSIBLE 2048.0

// plugin_init()
Register_Ham(Ham_TraceAttack, "func_breakable", "fw_traceatt_break")

public fw_traceatt_break(ent, attacker, float:damage, Float:direction[3], trace, bits)
{
new Float:start[3], end[3], fraction, multi
get_tr2(trace, TR_vecEndPos, end)
get_tr2(trace, TR_flFraction, fraction)

multi = fraction * SHOT_DISTANCE_POSSIBLE

xs_vec_mul_scalar(direction, multi, start)

// This is how to correctly get the start origin!
xs_vec_add(start, end, start)

}

Function true usage:

#define SHOT_DISTANCE_POSSIBLE 2048.0

public Ham_Shoot(attacker, damage, bits, bool:can_penetrate)
{
new Float:angles[3], Float:start[3], Float:end[3], Float:direction[3], Float:fakeend[3]

// Turn the angles in a true vector
pev(attacker, pev_angles, angles)
angle_vector(angles, ANGLEVECTOR_FORWARD, direction)

// We make this as a normal shot!
xs_vec_mul_scalar(direction, SHOT_DISTANCE_POSSIBLE, fakeend)

// Start origin
pev(attacker, pev_origin, start)
pev(attacker, pev_view_ofs, end)
xs_vec_add(end, start, start)

// Obtain the end shot origin
xs_vec_add(start, fakeend, end)

// From now this is how these variables will be used
// origin - start place (will remain constant!)
// end - end place (will remain constant!)
// angles - no use
// fakeend - dynamic start origin
// direction - will be used in the forwards (will remain constant!)

new ptr = create_tr2()

// Trace to the first entity
engfunc(EngFunc_TraceLine, start, end, DONT_IGNORE_MONSTERS, attacker, ptr)

new Float:fraction, hit = get_tr2(ptr, TR_pHit)
get_tr2(ptr, TR_flFraction, fraction)

// Update the fake start origin
get_tr2(ptr, TR_vecEndPos, fakeend)

// This means that we hited sky!
if (fraction != 1.0 && engfunc(EngFunc_PointContents, fakeend) == CONTENTS_SKY && hit == -1)
{
// Prepare the trace handle
set_tr2(ptr, TR_pHit, 0)

// Bullet trace!
ExecuteHamB(Ham_TraceAttack, 0, attacker, damage, direction, ptr, DMG_NEVERGIB | DMG_BULLET)

free_tr2(ptr)
return -1
}

if (hit == -1)
{
hit = 0
set_tr2(ptr, TR_pHit, hit)
}

ExecuteHamB(Ham_TraceAttack, hit, attacker, damage, direction, ptr, DMG_NEVERGIB | DMG_BULLET)

if (!can_penetrate)
{
free_tr2(ptr)
return 1
}

// Trace to the next entity
engfunc(EngFunc_TraceLine, fakeend, end, DONT_IGNORE_MONSTERS, hit, ptr)

hit = get_tr2(ptr, TR_pHit)
get_tr2(ptr, TR_flFraction, fraction)

// Update the fake start origin
get_tr2(ptr, TR_vecEndPos, fakeend)

if (hit == -1)

- direction - this parameter has a very important roll, it is the tangent of the line that the bullet goes

I don't understand this. Is it the direction vector from the attacker to the victim?

[ot_207]

I don't understand this. Is it the direction vector from the attacker to the victim?

Let me explain in vectors.
We have the endposition of the bullet.
ENDPOS
We have the gun tube from where the bullet was fired.
STARTPOS
Direction is xs_vec_normalize(ENDPOS-STARTPOS), it shows the angles.

[fysiks]

Ok that's what I thought. Tangent is not a good word to use there in this case. The tangent of the bullet's path is constantly changing throughout it's parabolic path (I don't know if they consider gravity for bullets in these games :|).

Gravity does not influence bullets. So Tangent is the best term (I think) to describe it.
If you have a better suggestion please let me know :).

"[Unit] vector in the direction of the bullets path."

[unit] only if it's normalized.

The tangent of a straight line is the line itself. When I first read it I was thinking perpendicular for some reason which would mean it was a plane lol :).

[ConnorMcLeod]

It's called normal vector i guess.

[Emp`]

NOTE The terms "perpendicular," "orthogonal," and "normal" all mean essentially the same thing - meeting at right angles. However, it is common to say that two vectors are orthogonal, two lines or planes are perpendicular, and a vector is normal to a given line or plane.

[fysiks]

Normalize => convert to vector of length 1 (aka unit vector).

!=

FakeMeta functions:
EngFunc_TraceTexture, DLLFunc_PM_FindTextureType

Description:
The TraceTexture function detects the texture of an entity from a direction
The FindTextureType function allows to get the type of the material of the texture.

Parameters:
engfunc(EngFunc_TraceTexture, ent, Float:start[3], Float:end[3], texture_name, len)
- ent is the entity that we want to get the texture
- start is the point from where the trace starts
- end is the point where the trace ends
- texture_name - here we save the texture name
- len - the texture_name string length
@Return
Nothing!

dllfunc(DLLFunc_PM_FindTextureType, texture_name)
- texture_name is the name of the texture that we have gotten with TraceTexture
@Return
It returns the material of the texture.


Constants:
The first function does not have any constants but if the name of the texture begins with '{' the texture is semi-transparent!

The letter constants are returned by the second function. "DLLFunc_PM_FindTextureType"

/*
C : concrete
D : dirt
G : grate
M : metal
N : snow
P : computer
S : slosh
T : tile
V : ventilation
W : wood
Y : glass
*/


new const material_array[] =
{
'C', 'D', 'G', 'M', 'N', 'P', 'S', 'T', 'V', 'W', 'Y'
}


Usage:
new texture_name[64], texture_type
engfunc(EngFunc_TraceTexture, 0, start, end, texture_name, charsmax(texture_name))
texture_type = dllfunc(DLLFunc_PM_FindTextureType, texture_name)

Notes:
- Improper use of these functions may crash the server!!!
- To avoid crashing the server use the TraceTexture:
-on any entities (even worldspawn) except players
-use this function only when there is at least one player connected
-the distance between the two points must be big! [> 2000.0]

[Arkshine]

You forget to say that the material returned is depending the materials.txt file. ( client ) So it's very limited. ( You forget N for Snow )

[ot_207]

You forget to say that the material returned is depending the materials.txt file. ( client ) So it's very limited.

It depends on the server config.

[Arkshine]

What do you mean ?

[ot_207]

What do you mean ?

I mean that every map has its own set of textures and every texture has its own material. And it is not client dependent.

[SnoW]

( You forget N for Snow )
Did someone call me?

[ot_207]

Added you to the constants :mrgreen:

[ConnorMcLeod]

And it is not client dependent.

Yes it is, unfortunately.

[Arkshine]

I mean that every map has its own set of textures and every texture has its own material. And it is not client dependent.

You're wrong. Most of maps use common textures from valve wad. But the material is listed in materials.txt (client file ) corresponding the texture. Only the default textures are listed there. ( it's possible that some maps when you install it on your pc modify the file to add its textures, but it rarely happens ). If you play a map which use custom textures not listed in this file, the default material will be 'Concrete'.

[ot_207]

Yes it is, unfortunately.

How can this be?
It traces the map that you have on your server not the client map.

You're wrong. Most of maps use common textures from valve wad. But the material is listed in materials.txt corresponding the texture. Only the default textures are listed there. If you play a map which use custom textures not listed in this file, the default material will be Concrete.

It is dependent on that but not on client!

[Arkshine]

I don't understand what you mean. The file is on the CLIENT and material is defined corresponding the texture in this file ONLY. DLLFunc_PM_FindTextureType called on client. Meaning if you use an unknow texture not listed, the material will bon concrete by default.

[ot_207]

I don't understand what you mean. The file is on the CLIENT and material is defined corresponding the texture in this file ONLY. DLLFunc_PM_FindTextureType called on client. Meaning if you use an unknow texture not listed, the material will bon concrete by default.

Than why does the function not have dllfunc(DLLFunc_PM_FindTextureType, texture_name, player_id) ??????

[Arkshine]

What. Why are you talking about player id ? lol I think, when the game is loading, it reads the file and loading in memory.

PM_FindTextureType is a client-side function.

[ot_207]

Then why doesn't it have the player_id in the arguments?
So that the server will now what material to look at.

[Arkshine]

Player has nothing to do here. Textures/materials stuff is done by the client, not server. ( like you can see the file is read when you load the game ). DLLFunc_PM_FindTextureType calls just PM_FindTextureType function on the client. I don't know how to explain properly sorry. lol. For sure sounds are played by player. If you modify the materials.txt file on your pc, removing all the textures, it will play always the concrete sound only for you. What you you need to understand is the material is found by checking the texture name in this file.

I understand that each material is what affects the client but normally the return values should only depend on the server map and server materials.txt and only that! In this situation you are right that the sounds are client side!

[Arkshine]

only depend on the server map and server materials.txt

It does already that !! Depending the texture used for the map and the texture listed by default in materials.txt you will get the right material or the default one.

[Edit] Ahhh "server". Sorry. Well there is probably a good reason for that.

[ot_207]

Fakemeta function:
EngFunc_EntitiesInPVS

Description:
This function checks entities that are in the PVS of an entity.
It can be used on all entities except worldspawn!

What is PVS?
PVS means potentially visible set, this means that the entities that we have in this list can be seen.
PVS does not hold just the entities that we see!
By knowing this we can get to the conclusion that PVS has the role of limiting data transfer for better internet connection/lower amount of data transfer!

So in small words I want to say something like this:
Entity that is in PVS => Can be seen => Data Transfer about that entity
Entity that it is not in PVS => Can not be seen => No data transfer => Save bandwidth

How does it work?
Well let's say that every room of the map is a cube.
We find ourselves in a room and that also means that we are in the cube of that room.
We can see the entities in the next rooms because the cubes of that room touch with the cube of the room we are in.

How do I use this function?
Well this function doesn't work like EngFunc_FindEntityInSphere so the HL engine has another method of providing the information.
At first this function returns a start entity and after that we can find the next entity using pev_chain/EV_ENT_chain. And so on, untill pev_chain is NULL.

Example Usage:
public whatisonPVS(id)
{
static next, chain
static class[32]

next = engfunc(EngFunc_EntitiesInPVS, id)
while(next)
{
pev(next, pev_classname, class, charsmax(class))
chain = pev(next, pev_chain)

server_print("Found entity in player (%i) PVS: ent(%i) class(%s)", id, next, class)

if(!chain)
break

next = chain
}
}

HamSandWich function:
Ham_TakeDamage

Description:
This function gives us info about the moment a player takes damage, when we use it as a forward. The return of the forward is a boolean, if it is set to 1 then the damage will be done if set to 0 then it will not be done!
It also can be used to give damage.
Here I will present how to correctly use this function!
You should use this function when you want to simulate an attack by a entity!


Usage:

#define OFFSET_LAST_HIT_GROUP 75
#define EXTRAOFFSET_PL_LINUX 5

// plugin_init()
RegisterHam(Ham_TakeDamage, "player", "fw_takedamage")

public fw_takedamage(victim, inflictor, attacker, Float:damage, bits)
{
// Victim is the entity that has been taken damage
// Inflictor is the entity that directly gived damage
// Attacker is the owner of the inflictor
// If Attacker == Inflictor that means that the damage was inflicted by a player (such as gun shot/knife stab)
// Damage the damage
// Bits the type of damage represented in Bitsums

// For grenade damage (In CS) the bits is equal to (1<<24)
// Basically for hooking the he grenade damage is to put this condition
// if (bits & (1<<24))

// For bullet/knife damage (In CS) the bits are equal to (DMG_BULLET | DMG_NEVERGIB)
// Basically for hooking the shot damage is to put this condition
// if (bits & (DMG_BULLET | DMG_NEVERGIB))

// Now the most subtile element is that we can get the last hitgroup where the damage was dealt

new hitgroup = get_pdata_int(victim, OFFSET_LAST_HIT_GROUP, EXTRAOFFSET_PL_LINUX)
}

How to properly execute damage? This is the way to do it!

#define OFFSET_LAST_HIT_GROUP 75
#define EXTRAOFFSET_PL_LINUX 5

new const Float:hitgroup_multi[] =
{
1.0, // HIT_GENERIC
4.0, // HIT_HEAD
1.0, // HIT_CHEST
1.25, // HIT_STOMACH
1.0, // HIT_LEFTARM
1.0, // HIT_RIGHTARM
0.75, // HIT_LEFTLEG
0.75 // HIT_RIGHTLEG
0.0 // HIT_SHIELD
}

stock Ham_ExecDamage(victim, inflictor, attacker, damage, hitgroup, bits)
{
set_pdata_int(victim, OFFSET_LAST_HIT_GROUP, hitgroup, EXTRAOFFSET_PL_LINUX)
ExecuteHam(Ham_TakeDamage, victim, inflictor, attacker, damage*hitgroup_multi[hitgroup], bits)
}

stock Ham_ExecDamageB(victim, inflictor, attacker, damage, hitgroup, bits)
{
set_pdata_int(victim, OFFSET_LAST_HIT_GROUP, hitgroup, EXTRAOFFSET_PL_LINUX)
ExecuteHamB(Ham_TakeDamage, victim, inflictor, attacker, damage*hitgroup_multi[hitgroup], bits)
}

stock HamRadiusDamage(ent, Float:radius, Float:damage, bits)
{
new target = -1, Float:origin[3]
pev(ent, pev_origin, origin)

while(( target = find_ent_in_sphere(target, origin, radius) ))
{
static Float:o[3]
pev(target, pev_origin, o)

xs_vec_sub(origin, o, o)

// Recheck if the entity is in radius
if (xs_vec_len(o) > radius)
continue

Ham_ExecDamageB(target, ent, pev(ent, pev_owner), damage * (xs_vec_len(o) / radius), HIT_GENERIC, bits)
}
}

Also to mention that knife damage also equals DMG_BULLET | DMG_NEVERGIB, so if you wanted to catch that you would have to check player's weapon like with other guns.

If the distance between Entity and Destination is less than the required distance, the entity will pass over that point.


Usage :
engfunc(EngFunc_MoveToOrigin, iEnt, Float:Destination[3], Float:Distance, iMoveType);
Parameters
iEnt = Entity index
Destination[3] = A Coordinate toward which the entity moves
Distance = The distance to move the entity
iMoveType = This is the MOVE_* option used for monsters and players to change the behaviour of the movement

#define MOVE_NORMAL 0 // normal move in the direction monster is facing
#define MOVE_STRAFE 1 // moves in direction specified, no matter which way monster is facing
#define MOVE_STUCK_DIST 32 // if a monster can't step this far, it is stuck.
#define MOVE_START_TURN_DIST 64 // when this far away from moveGoal, start turning to face next goal


Caveats :

iEnt must be on ground
If there's an object closer than Distance that iEnt could collide then the movement is not done
If there's a ramp, it works like an object and the movement is not done

[Exolent[jNr]]

About MOVETYPE there's no clew of what it does this option within the function.
Almost every option gives the same result, but if you use MOVETYPE_NONE, you could get random movements.

...

(tested with players only)

That may be why. Test with an entity you created.

[Arkshine]

Movetype are that :


#define MOVE_NORMAL 0 // normal move in the direction monster is facing
#define MOVE_STRAFE 1 // moves in direction specified, no matter which way monster is facing

#define MOVE_STUCK_DIST 32 // if a monster can't step this far, it is stuck.
#define MOVE_START_TURN_DIST 64 // when this far away from moveGoal, start turning to face next goal


It's used mainly for monster but should work on player.

EngFunc_CheckVisibility

Description:
This function is used to check if an entity is in your PVS.
It can be used on all entities except worldspawn!
Here I will show you how to use is, since this function has a paramater that must be obtained in a special way!

What is PVS?
PVS means potentially visible set, this means that the entities that we have in this list can be seen.

We find ourselves in a room and that also means that we are in the cube of that room.
We can see the entities in the next rooms because the cubes of that room touch with the cube of the room we are in.

Well this function has a parameter that must be obtained in a special way. That is the "pset" parameter.
Here is how you obtain that parameter.
Note: The parameter is player only, that means that if you get pset for example for a player that has the id "1". When you use this function on an entity it will check whether that entity is in PVS of the Player id "1".

Example Usage:
new g_cl_pset[33]

public plugin_init(id)
{
register_forward(FM_AddToFullPack, "pfw_atfp", 1)
}

public pfw_atfp(es, e, ent, host, flags, player, set)
{
g_cl_pset[host] = set

return FMRES_IGNORED
}

stock is_ent_in_player_pvs(id, entity)
{
return engfunc(EngFunc_CheckVisibility, entity, g_cl_pset[id])
}

stock get_pvs_players(id, players[32], num, flags[], team[])
{
if (!is_user_connected(id))
return 0

get_players(players, num, flags, team)

for (new i=0;i<num;i++)
{
if (!is_ent_in_player_pvs(id, players[i]))
{
num--;

for (new j=i;j<num;j++)
{
players[j] = players[j+1]
}

i--
}
}

return 1
}

http://img507.**************/img507/7762/playerskeleton.jpg (http://img507.**************/my.php?image=playerskeleton.jpg)


Usage:
// ENTITY is the player entity id
// BONE_NUMBER you have to choose from the list above
// bone_origin[3] is the vector where we save the bone origin
// bone_angles[3] the vector that holds the angles of the bone.
engfunc(EngFunc_GetBonePosition, ENTITY, BONE_NUMBER, Float:bone_origin[3], Float:bone_angles[3])

Useful Stocks:
These stocks are made for CS/CZ you need to port them to other mods.

This gets the hitgroup of the bone.

return HIT_LEFTLEG

if (BONE_HIT_LEFTLEG < number <= BONE_HIT_RIGHTLEG)
return HIT_RIGHTLEG

return HIT_GENERIC
}

This gets the closest bone to the gunshot [Use this in FM_TraceLine and Ham_TraceAttack

#define DISTANCE_CLEAR_HIT 2.0

stock find_closest_bone_to_gunshot(victim, Float:endtrace[3])
{
new Float:angles[3], Float:origin[3], Float:dist = 9999999.99, Float:curorigin[3], bone_nr

Fakemeta function :
EngFunc_FindClientInPVS

Description :
Return the next "player" entity in someone PVS using a global loop.

Usage :
iEnt2 = engfunc(EngFunc_FindClientInPVS, iEnt);

Parameters
iEnt = Source entity. Seek someone within of iEnt PVS

Unlike EngFunc_EntitiesInPVS (http://forums.alliedmods.net/showpost.php?p=933833&postcount=68), it does not return a series of chained entities.

It works like a global loop of entities.
No matter which source entity you use, this function maintains the last index used and returns the next entity in source entity PVS.

This function must be called severals times to find every entity in PVS and also can return the source entity but it can't be called twice inside the same function because it will return the same entity.


Notes :
It seems you can call this function once between some forward (maybe UpdateClientData, Think, AddToFullPack or some other).

It's not clear the main purpose of this function because you can get similar results with FindEntitiesInPVS.
CheckVisibility and FindEntitiesInPVS are better functions to use.

[ot_207]

I suggest doing an example of that function.
Since it is harder to use than EngFunc_FindEntityByString or FindEntityInSphere

[Starsailor]

Fakemeta function :
EngFunc_AlertMessage

Description :
Prints an alert message.

Usage:
engfunc(EngFunc_AlertMessage, AlertType, const Message)


AlertType can be:
at_notice -
at_console - same as at_notice, but forces a ConPrintf, not a message box, prints output to server console, but only if 'developer' is 1.
at_aiconsole - same as at_console, but only shown if 'developer' is 2.
at_warning -
at_error -
at_logged - prints output to server logs and console.

[joropito]

Yes, too complicated to use this function and I can't find a good use of this (why not use EntitiesInPVS instead of this?).

It seems you can call this function once between some forward (maybe UpdateClientData, Think, AddToFullPack).
I'm thinking this based on my tests and what Arkshine said in other post.

If you call this function 1000 times inside a loop, it always returns the same entity.

In fakemeta there's a FM_FindClientInPVS but if you try to forward that call, it's not even called (tried to run, jump, shoot, kill, plant bomb and wait the explosion, drop guns, throw nades, etc).

Updated.
I think it doesn't have problems. I think it's as is :)

[Arkshine]

Yeah I remember it's just a pain how works this function. If you refer at a post -somewhere- there is a delay between each update, and it matches with the frequency of the "entity-without-classname" ( This entity is created right after max_clients ; if there is entities created in plugin_precache(), this entity will be created after that ). This entity is updated between .25 to 0.3s. It could be used there but it's more easy and efficient to use FindEntsInPVS.

[ot_207]

Those entities are the ones that ocupy a slot for a player.

When a player connects the entity "without_classname" gets the "player" classname. That is why I think that you received the SVC_BAD error. The player entity could not be correctly created.

Fakemeta function :
EngFunc_AnimationAutomove

Description :
Plays the selected animation on entity

Usage :
entity_set_float(iEnt, EV_FL_framerate, fFrameRate);
entity_set_int(iEnt, EV_INT_sequence, iSequence);
engfunc(EngFunc_AnimationAutomove, iEnt, fTime);

Parameters
fFrameRate = Frame rate of desired animation.
iSequence = Sequence to play.
iEnt = Source entity.
fTime = It seems to not affect the animation. Maybe for internal use.

First you have to select the sequence and the desired frame rate. Then you can start the animation.
It will run in an endless loop.

It seems to work only on non-player entities

You need to set MOVETYPE_ and SOLID_ in entity.

Are you sure that TestOrigin is a valid target?

[solano]

pev( TargetIndex, pev_origin, Origin );
pev( TargetIndex , pev_v_angle, Angles );



angle_vector( Angles, ANGLEVECTOR_FORWARD, Forward );
xs_vec_mul_scalar( Forward, 150.0, Forward );
xs_vec_add( Origin, Forward, Origin );

this is how i got the origin

[joropito]

I've only tested with non-monsters entities but try this on that entity


set_pev(ent, pev_solid, SOLID_BBOX)
set_pev(ent, pev_movetype, MOVETYPE_TOSS)
set_pev(ent, pev_maxspeed, 9999.0)


I don't know if BBOX it's right for that entity.

i want to make the monster "walk" to a specific location
walk is in "" because while walking if he sees a player he should start attacking him

I've tried with func_breakable entities and it walks fine and only tested with MOVETYPE_TOSS.
Try with that kind of entity, movetype and setup the model you want.

[Arkshine]

I don't think it will work with (real) monsters from HL1 because such monsters have predefined paths. I've tried and zombies are warp directly. Don't know how to force to generate paths. A way could be to create a dummy entity at the origin you want, then forcing the zombie to see it as enemy ( pev_enemy ) ; it may works.

[joropito]

For bots, EngFunc_RunPlayerMove
For non-intelligent entities, EngFunc_MoveToOrigin
For monsters, EngFunc_WalkMove

Not tested but...

EngFunc_WalkMove(edict_t *ent, float yaw, float dist, int iMode)


Where:

- You get yaw using EngFunc_VecToYaw to convert vector to yaw (it returns a float value)
- The distance to walk is dist
- iMode

#define WALKMOVE_NORMAL 0 // Normal walkmove
#define WALKMOVE_WORLDONLY 1 // Doesn't hit ANY entities, no matter what the solid type
#define WALKMOVE_CHECKONLY 2 // Move, but don't touch triggers


Give a try and tell us.

[Arkshine]

Yeah, totally forget about this one. I'm blind because I'm reviewing the SinglePlayer HLSDK too.

Anyway, i've tested and the same result, zombie is warped instead of walking. Probably because there is not path available at this time.

[joropito]

Yeah, totally forget about this one. I'm blind because I'm reviewing the SinglePlayer HLSDK too.

Anyway, i've tested and the same result, zombie is warped instead of walking. Probably because there is not path available at this time.

Take a look into hlsdk-2.3-p3/singleplayer/dlls/monsters.cpp

int CBaseMonster :: CheckLocalMove


It says something about making WALK_MOVE for every step


// this loop takes single steps to the goal.
for ( flStep = 0 ; flStep < flDist ; flStep += LOCAL_STEP_SIZE )
...
...
...
if ( !WALK_MOVE( ENT(pev), flYaw, stepSize, WALKMOVE_CHECKONLY ) )
...


EDIT:

Remember to set MOVETYPE_WALK on the monster!!!!

[Arkshine]

The same. Stepping by 16 units doesn't help. Well this function is just to test the origin step by step.

Remember to set MOVETYPE_WALK on the monster!!!!

Not sure if I should do because zombie spawns already with a specific configuration. I don't see any reference of such move type for monsters. MOVETYPE_WALK would be only for player.


void CZombie :: Spawn()
{
Precache( );

SET_MODEL(ENT(pev), "models/zombie.mdl");
UTIL_SetSize( pev, VEC_HUMAN_HULL_MIN, VEC_HUMAN_HULL_MAX );

pev->solid = SOLID_SLIDEBOX;
pev->movetype = MOVETYPE_STEP;
m_bloodColor = BLOOD_COLOR_GREEN;
pev->health = gSkillData.zombieHealth;
pev->view_ofs = VEC_VIEW;// position of the eyes relative to monster's origin.
m_flFieldOfView = 0.5;// indicates the width of this monster's forward view cone ( as a dotproduct result )
m_MonsterState = MONSTERSTATE_NONE;
m_afCapability = bits_CAP_DOORS_GROUP;

MonsterInit();
}


Edit: I was right, it crashes the server saying that's a bad movetype.

[joropito]

I can't test right now (I'm at work).
I'm sure you have read my edit about movetype_walk

You can also take a look at hlsdk-2.3-p3/singleplayer/dlls/roach.cpp in CRoach::Move called from MonsterThink

As I see, the properties of the roach are

- SOLID_SLIDEBOX
- MOVETYPE_STEP

[Arkshine]

Yes I've read and already answered. See my edit. :)

Edit : About the roach, it seems that the roach runs by being 'warped' very often ( Think function ) only few units each time.

Edit2: This function seems interesting :


BOOL CBaseMonster::MoveToLocation( Activity movementAct, float waitTime, const Vector &goal )
{
m_movementActivity = movementAct;
m_moveWaitTime = waitTime;

m_movementGoal = MOVEGOAL_LOCATION;
m_vecMoveGoal = goal;
return FRefreshRoute();
}

This is not technically true either. It only works for player spawn when the second argument is "player".

[joropito]

Fakemeta function :
EngFunc_TraceToss

Description :
Trace the point where some entity movement will finish.
If for some reason the entity movement must be blocked for other entity (or worldspawn), TraceToss will detect that situation taking in account the original entity bounding boxes.

Usage :

engfunc(EngFunc_TraceToss, ent, skipent, tr);

Parameters
ent = The entity which movement we want to trace
skipent = The entity to skip in trace
tr = trace result

Example:

If you open the attached image, you can see a player jumping and 2 points.

Start Point: Is the origin of the player when TraceToss was called
End Point: Is the point returned in TR result

So the player is making a parabola from START to END.
The green line is only for testing purposes and show from where to where the trace is.
This was tested with gravity = 400.

[ConnorMcLeod]

Pass the player's id, not 0.

[01101101]

Pass the player's id, not 0.

The result will be the same whether you show it to all players or just him o.o

This function seems really nice for tracing a line from the nade start point to the end point (before it actually falls). The bad thing is that the only way of doing a curve is with many lines lol (I think, maybe there is a message for a curve but I've never seen it)

[Arkshine]

}

[Arkshine]

You miss the point that this param has nothing to do with "to show to all players or just him".

skipent = The entity to skip in trace

[joropito]

i tested this function with this code

Try to execute this function when you're jumping.

The bad thing is that the only way of doing a curve is with many lines lol (I think, maybe there is a message for a curve but I've never seen it)

If you need to draw the parabola, you must do it at think and not with this functions.

I've tested this function in this way:

- Long jump
- Execute this function as fast as possbile to draw a line.
- I get a lot of lines from every point in the parabola to the same end

[Arkshine]

Try to execute this function when you're jumping.

Why do you say that ? I mean the skipent exists to avoid this problem to ignore the entity where the trace starts. It's the same as TraceLine if you start a trace from your origin it will collide on you.

[joropito]

Why do you say that ? I mean the skipent exists to avoid this problem to ignore the entity where the trace starts. It's the same as TraceLine if you start a trace from your origin it will collide on you.

The function works when you're moving off-ground.

If you're standing up on worldspawn, you'll get the same origin as the start point.

If you're jumping, you'll get the point where you will touch again worldspawn.

One funny thing.
If you jump and you're going to touch sky (or ceiling) this trace will be that point and not where you will be back at floor.

So, this function returns the point where you will be stopped (at the fly) by something.

[Arkshine]

If you're standing up on worldspawn, you'll get the same origin as the start point.

Just tested again, it works fine for me whatever I'm moving, jumping or not.

[01101101]

If you need to draw the parabola, you must do it at think and not with this functions.


Yes, but with think it draws the line while it moves in the air.
With this function you could draw the parabola before it is actually thrown.
This wouldn't be hard since unlikely source random nades motion, cs is like static, the end position will be always the same, the curve ratio, and many other factors.

[Starsailor]

Try to execute this function when you're jumping.


Yes, Now It is working for me

What do you want to do exactly?

[AlexALX]

What do you want to do exactly?determine whether the player in a trigger and the player SOLID_NOT (like touch, touch do not work with SOLID_NOT).

[ot_207]

determine whether the player in a trigger and the player SOLID_NOT (like touch, touch do not work with SOLID_NOT).

Well, you can make the entity think and add an entity_range check to it. That is a way IMO.

I was pretty strange that there's no this function in amxmodx, but here, too, checking through absmun absmax and not suitable to me.

It doesn't matter if your entity has the SOLID_NOT flag, EngFunc_FindEntityInSphere whill find your entity and doesn't work like you said. Did you tried at least the function ??!

What's the difference between InOpen and StartSolid values from traceline function? I mean, StartSolid detects if starts on a solid object (brush) and InOpen detects if starts on a entity?

Thank you all for creating this tread, it really helped me alot to understand much better of how to use!

Fakemeta function:
EngFunc_TraceLine

Description:
This function traces between 2 origins and gives us information about it.

The constants that we can use in flags:
#define DONT_IGNORE_MONSTERS 0
#define IGNORE_MONSTERS 1
#define IGNORE_MISSILE 2
#define IGNORE_GLASS 0x100

These constants can be used together.
Ex: IGNORE_MISSILE | IGNORE_MONSTERS | IGNORE_GLASS - This makes the traceline ignore missiles, monsters (players) and glass.

Here is a drawing that will show you how it works!
engfunc(EngFunc_TraceLine, start, end, IGNORE_GLASS, 0, tr)

Functions that come with the TraceLine pack:
// Description: This creates a trace handle!
// It is important to use because we don't want our plugins to mess with eachothers info!
new ptr = create_tr2()

// Description: This creates a trace handle!
// It is important to use because we don't want our plugins to mess with each others info!
free_tr2(ptr)

// Description: Gets/Sets information from/in the trace_handle
[g|s]et_tr2(trace_handle, CONSTANT, number_if_needed!)

CONSTANT Expresion has this posible values:

enum TraceResult
{
TR_AllSolid, // int
TR_StartSolid, // int
TR_InOpen, // int
TR_InWater, // int
TR_flFraction, // float
TR_vecEndPos, // float array[3]
TR_flPlaneDist, // float
TR_vecPlaneNormal, // float array[3]
TR_pHit, // int (edict_t*)
TR_iHitgroup, // int
};
The float and array values need the third argument! Example:

new allsolid = get_tr2(trace, TR_AllSolid)
new startsolid = get_tr2(trace, TR_StartSolid)
// TR_StartSolid is a boolean that says whether you were "inside" something
// (usually the world) when the trace started (point A)
// TR_AllSolid tells you if you ever got out of the "inside" or not.

new inopen = get_tr2(trace, TR_InOpen)
// TR_InOpen means that the start point is in Open
// That means in the world and not in an ent or something

new hit = get_tr2(trace, TR_pHit)
// What was hit by the traceline. It will either be a player index,
// entity index, 0 (part of map), or -1 (didn't hit anything;
// doesn't happen with player tracelines).

new hitgroup = get_tr2(trace, TR_iHitgroup)
// If the traceline hit another player, returns will be HIT_HEAD,
// HIT_CHEST, HIT_LEFTLEG... etc. If the traceline hit part of the
// map, this returns HIT_GENERIC.

new Float:fraction
get_tr2(trace, TR_flFraction, fraction)
// Returns a number between 0.0 and 1.0, indicating how far the
// traceline traveled start to end before it hit something. Depending
// on what conditions were passed to this traceline forward function,
// it could either be a wall or another entity.

new Float:end_origin[3]
get_tr2(trace, TR_vecEndPos, end_origin)
// The official end of the traceline. Not necesarily the same as the
// second argument passed to this traceline forward function.

new Float:normal[3]
get_tr2(trace, TR_vecPlaneNormal, normal)
// Returns a 1 unit long vector normal to the spot that it hit. Note
// that "normal" has a special connotation here. It doesn't mean "regular."

Example Stock:
stock is_wall_between_points(Float:start[3], Float:end[3], ignore_ent)
{
// Create the trace handle! It is best to create it!
new ptr = create_tr2()

// The main traceline function!
// This function ignores GLASS, MISSILE and MONSTERS!
// Here is an example of how you should combine all the flags!
engfunc(EngFunc_TraceLine, start, end, IGNORE_GLASS | IGNORE_MONSTERS | IGNORE_MISSILE, ignore_ent, ptr)

// We are interested in the fraction parameter
new fraction
get_tr2(ptr, TR_flFraction, fraction)

// Free the trace handle (don't forget to do this!)
free_tr2(ptr)

// If = 1.0 then it didn't hit anything!
return (fraction != 1.0)
}

I have Question :)
What is "GLASS", what does that mean?
Is it some kind of entity like func_wall or it is texture material type?

[Arkshine]

Like the one in cs_assault, T side, you see ? But It's most likely related to any entity with some render.

Fakemeta function:
EngFunc_CanSkipPlayer

Description: Returns 1 or 0 depending of client's cl_lw cvar value (if cl_lw different from 0, returns 1). This functions is used by the mod for checking if player has weapon prediction enabled. Mod uses CanSkipPlayer on weapons, directly on SendWeaponAnim function.

If client haves cl_lw cvar enabled, it means that haves weapon prediction enabled = no need to send weapons animations.
Usage:

if(engfunc(EngFunc_CanSkipPlayer(index))
{
// client has weapon prediction enabled
}
else
{
// client has weapon prediction disabled, server will sent him everything from his weapons.
}Parameters:index = client's index (must be a player)

Not really an important snippet, but it will be useful for someone. May this function be unknown for a lot of scripters.

Fakemeta function:
EngFunc_Time

Description: Returns time in seconds (float) since the game started. Rather the same as tickcount(). It seems to not be used by the mod (it's useless anyway).
Usage:

new Float:flElapsedTime = Float:engfunc(EngFunc_Time)
server_print("%.2f seconds passed since the server started", flElapsedTime)
new Float:flStartTime = Float:engfunc(EngFunc_Time)
MyVeryBigFunction()

SpamArkshineSteamChat()
server_print("Execution time: %f", Float:engfunc(EngFunc_Time) - flStartTime)Parameters:no params for this function

Another not really important function, but as many others, it's unknown for many scripters.

[HamletEagle]

@meTaLiCroSS, from what I see EngFunc_Time acts like get_gametime. AFAIK the value returned by get_gametime is increased only in next frame. In your last example, if the execution of the 3 private functions happen in the same frame, it will print 0. Is this right ?

I posted it because I researched the engine and found it usage, it has nothing to do with get_gametime(). Time will always return a difference of time (substracting 2 values from get_systime() as example)
