I think that we all need to contribute to this topic so let's get it started.

Fakemeta function:
PHP Code:
EngFunc_PointContents 
Description:
This function checks an origin and gives us information of its whearabouts.

The constants that this function returns are these:
Code:
#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:
PHP Code:
static Float:origin[3]
static 
result
result 
engfunc(EngFunc_PointContentsorigin)
// 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. )

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

Fakemeta function:
PHP Code:
EngFunc_TraceLine 
Description:
This function traces between 2 origins and gives us information about it.

The constants that we can use in flags:
PHP Code:
#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!
PHP Code:
engfunc(EngFunc_TraceLinestartendIGNORE_GLASS0tr
[IMG]http://img529.**************/img529/1863/traceline1.jpg[/IMG]

PHP Code:
engfunc(EngFunc_TraceLinestartendDONT_IGNORE_MONSTERS0tr
[IMG]http://img529.**************/img529/1415/traceline2.jpg[/IMG]

PHP Code:
engfunc(EngFunc_TraceLinestartendIGNORE_GLASS0tr
[IMG]http://img529.**************/img529/5815/traceline3.jpg[/IMG]

PHP Code:
engfunc(EngFunc_TraceLinestartendIGNORE_GLASS0tr
[IMG]http://img529.**************/img529/326/traceline4.jpg[/IMG]

Functions that come with the TraceLine pack:
PHP Code:
// 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() 
PHP Code:
// 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
PHP Code:
// Description: Gets/Sets information from/in the trace_handle
[g|s]et_tr2(trace_handleCONSTANTnumber_if_needed!) 
CONSTANT Expresion has this posible values:
Code:
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:

PHP Code:
    new allsolid get_tr2(traceTR_AllSolid)
    new 
startsolid get_tr2(traceTR_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(traceTR_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(traceTR_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(traceTR_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
(traceTR_flFractionfraction)
    
// 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(traceTR_vecEndPosend_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(traceTR_vecPlaneNormalnormal)
    
// 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:
PHP Code:
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_TraceLinestartendIGNORE_GLASS IGNORE_MONSTERS IGNORE_MISSILEignore_entptr)
    
    
// We are interested in the fraction parameter
    
new fraction
    get_tr2
(ptrTR_flFractionfraction)
    
    
// 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:
PHP Code:
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:
[IMG]http://img265.**************/img265/2395/screenshot053.png[/IMG]


If we use
PHP Code:
engfunc(EngFunc_FindEntityInSphere, -1originradius
The function in the situation above will return 1!
PHP Code:
engfunc(EngFunc_FindEntityInSphere20originradius
The function in the situation above will return 30!
PHP Code:
engfunc(EngFunc_FindEntityInSphere100originradius
The function in the situation above will return 0, meaning that it didn't find an entity with an id grater than 100!


Usage:
PHP Code:
engfunc(EngFunc_FindEntityInSphereent_to_startoriginradius

Thanks! That was just as an example. If someone would do a 3d design it would be great .
