Hey guys i'm still a noob at coding so i was hoping someone could lend me a hand. I am trying to check for things that the player is aiming at.

Something like this:

PHP Code:

if(engfunc(EngFunc_PointContents,origin) == CONTENTS_SKY) 
    {  
       client_print(id, print_chat, "This is the sky")
    } 


So what i would like to do is check for entities where i'm pointing at certain maps. I already checked CONTENTS and it had water, lava, etc...

But for my case i need to check for a door and lets say... moving platforms...

So how could I perform a check like this for entities like func_door and func_train? And possibly other entities aswell?

get_user_aiming and check the returned index classname ?

PHP Code:

new Target, body, EntClassName[20]
get_user_aiming(id, Target, body)
pev(Target, pev_classname, EntClassName)
if(equal(EntClassName, "func_door"))
{
    //aiming at a func_door ent
} 


[HamletEagle]

Well, this should work

PHP Code:

stock bool: IsAimingAtEnt(id, const EntClassName[])
{
    if(EntClassName[0] == EOS || !is_user_alive(id))
    {
        return false
    }
    
    new Target, Body, ClassName[20]
    get_user_aiming(id, Target, Body)
    pev(Target, pev_classname, ClassName)
    if(equal(ClassName, EntClassName))
    {
        return true
    }  
    return false
} 


And:

PHP Code:

if(IsAimingAtEnt(id, "func_door"))
{
}

sry i was gone for so long, i was out of town...

I ran into a little problem, i'm using an origin with 3 coordinates. So i need to make a check at that origin for the entities. Also how can i check if the entity at the origin is a player?

Something like:

PHP Code:

static Float:Origin[3]

//i'm using a stock that returns the coordinates of the origin

if (equal(entity at origin, "func_door"))
{
// This is a door...
}

//How do i check if it's a player?
if (equal(entity at origin, Player))
{
// This is a player...
}

you can use classname: "player"
Yet, i guess the most recommended is to check if the entity index is a player.

[safetymoose]

ok, so i can just check for the classname "Player".

But i still need to make the check using the origin. I have to check the origin for entities, such as doors.

[HamletEagle]

If you want know if an entity is player the best ideea is to check it's index. Checking by classname require also an !is_user_bot check, because bots have player class too(needed if you only want true players).

If I get what your request is, you want to check if at some origins is an ent with certain classname and you don't have it's index.

Didn't tested, but should work.

PHP Code:

stock EntAtOrigin(Float:Origin[3], const EntClassName[])
{
    static MaxEntities
    new Float:EntOrigin[3], ClassName[20], i
    new bool:SameOrigins = true
    
    if(!MaxEntities)
    {
        MaxEntities = global_get(glb_maxEntities)
    }
    for(new Ent; Ent < MaxEntities; Ent++)
    {
        if(pev_valid(Ent))
        {
            pev(Ent, pev_origin, EntOrigin)
            
            for(i = 0; i < 3; i++)
            {
                if(Origin[i] != EntOrigin[i])
                {
                    SameOrigins = false
                }
            }
            if(SameOrigins)
            {
                pev(Ent, pev_classname, ClassName)
                if(equal(ClassName, EntClassName))
                {
                    return true
                }
            }
        }
    }
    return false
} 


Also, your problem sounds like an XY one, you should explain us what you want to do so we can give you the best way. If you say that you use a stock to get the origin, this means that you get them from an index, if you have it's index simply do:

PHP Code:

new MaxPlayers
MaxPlayers = get_maxplayers()
if(1 <= index <= MaxPlayers)
{
    //this entity is a player
} 


[safetymoose]

Well, you were right, it was better to go with indexes then with an origin. I managed to get it working with indexes, and i'm very satisfied. Thank you HamletEagle

I just need 1 more thing.

PHP Code:

set_pev(ent, pev_owner, id) 


Is it possible to make this work with certain entities? I would like to prevent collision of this entity with other entitities(not all, just a few), so is it possible to make this?

PHP Code:

set_pev(ent, pev_owner, "some classnames") 


[HamletEagle]

No, pev_owner expects an integer. You are right that an entity is not solid for it's owner, but you can't use it like you want to do. AFAIK an entity can have only one owner at a time, so you should search for another method.

Do you want to allow an ent to go through another ent or just block the touch(because if they touch something happen) ?

Try to: hook touch with engine(you can specify both toucher and touched classnames) and supercede the call. This should prevent them from colliding.

[safetymoose]

well here's what i tried and failed. Think you can correct it?

PHP Code:

// in plugin_init()
RegisterHam(Ham_Touch, "ent", "ent_touch")

//somewhere else
public ent_touch( ent , ent2 )
{
    if( !pev_valid( ent2 ) )
        return HAM_IGNORED
    static iclassname[31]
    pev(ent2, pev_classname, iclassname, charsmax(iclassname))
    if( equal( iclassname, "1st classname") || equal( iclassname, "2nd classname") || equal( iclassname, "3rd classname") )
        {
        return HAM_SUPERCEDE
        }
    return HAM_IGNORED
} 


I also tried

PHP Code:

register_touch( "ent", "ent2", "ent_touch") 


Still doesnt work...
