I've made a test map, added one env_sprite entity and named it "sprite_test". This plugin is supposed to spam a chat message to each player only if the entity('s origin) is inside the players' 3D viewcone. However, it does not.

PHP Code:

#include <amxmodx>
#include <engine>
#include <fakemeta>
#include <hamsandwich>

new Float:fTestOrigin[3];

public plugin_init()
{
    register_plugin("Viewcone Test", "1.0", "ridavcrum");

    RegisterHam(Ham_Think, "player", "HamPlayerThink");
    
    new TestSprite = find_ent_by_target(-1, "sprite_test");
    pev(TestSprite, pev_origin, fTestOrigin);
}

public HamPlayerThink(id)
{
    if(is_in_viewcone(id, fTestOrigin, 1))
        client_print(id, print_chat, "IN VIEWCONE");
} 


What am I doing wrong here?

I've also tried replacing find_ent_by_target with find_ent_by_class with "env_sprite" as the second parameter, without any luck.

can you try:

is_visible( playerID, entityID )

while my testing i got correct results in 90% of the time (was bugged while in Spec)

Nothing, nothing at all. I've even swapped the ID's between the player and the env_sprite. No error logs, no nothing. Strange...

Did you confirm the entity is spawned in a place that can be in your player viewcone? Are you really searching for the entity in plugin_init()? Maybe it doesn't exist yet.

The function works, aim at a player and say "test"

PHP Code:


#include <amxmodx>
#include <engine>
#include <fakemeta>
#include <hamsandwich>

new Float:fTestOrigin[3];

public plugin_init()
{
    register_plugin("Viewcone Test", "1.0", "ridavcrum");

    register_clcmd( "say test" , "Test" );
}

public Test( id )
{
    new pID;
    
    set_task( 0.1 , "ViewconeTest" , id , .flags="b");
    get_user_aiming( id , pID );
    pev(pID, pev_origin, fTestOrigin);
    
    client_print( id , print_chat , "Found ent at {%f, %f, %f}" , fTestOrigin[0],fTestOrigin[1],fTestOrigin[2])
}

public ViewconeTest( id )
{
    if ( is_in_viewcone( id , fTestOrigin , 1 ) )
        client_print(id, print_chat, "IN VIEWCONE");
}

Actually, I've been playing around my code a bit and tried different methods. The entity is there. I'm getting the logs I want. For example, in my testmap, the sprite entity has an id of 38, as seen in logs.

PHP Code:

#include <amxmodx>
#include <engine>
#include <fakemeta>
#include <hamsandwich>

new TestSprite = -1;
new Float:fTestOrigin[3];

public plugin_precache()
{
    register_forward(FM_Spawn, "FwdSpawn");
}

public plugin_init()
{
    register_plugin("Viewcone Test", "1.0", "ridavcrum");

    RegisterHam(Ham_Think, "player", "HamPlayerThink");
}

public FwdSpawn(ent)
{
    log_amx("ENTITY: %d, START", ent);
    
    if(!pev_valid(ent))
    {
        log_amx("ENTITY: %d, INVALID", ent);
        return FMRES_IGNORED;
    }
    
    log_amx("ENTITY: %d, VALID", ent);
        
    new ClassName[32];
    pev(ent, pev_classname, ClassName, charsmax(ClassName));
    
    log_amx("ENTITY: %d, CLASSNAME: %s", ent, ClassName);
    
    if(equali(ClassName, "env_sprite"))
    {
        new TargetName[32];
        pev(ent, pev_targetname, TargetName, charsmax(TargetName));
        
        log_amx("ENTITY: %d, TARGETNAME: %s", ent, TargetName);
        
        if(equali(TargetName, "sprite_test"))
        {
            TestSprite = ent;
            
            log_amx("ENTITY: %d, END !!", ent);
            return FMRES_HANDLED;
        }
    }
    
    log_amx("ENTITY: %d, END", ent);
    return FMRES_IGNORED;
}

public HamPlayerThink(id)
{
    if(is_in_viewcone(id, fTestOrigin, 1) || is_visible(id, TestSprite))
        client_print(id, print_chat, "%s%s", is_in_viewcone(id, fTestOrigin, 1) ? "IN_VIEWCONE" : "", is_visible(id, Sprite) ? " | IS_VISIBLE" : "");
} 


None return true. Bleh!

Yes, I can definitely see the entity. It's in the middle of the room, basically.

[Bugsy]

Do a server print of the entity's origin after this...classic debugging.

pev(TestSprite, pev_origin, fTestOrigin);

[redivcram]

Huh. Weird. The origin is kinda wrong. The entity is clearly placed at one origin while the method with the entity's origin returns an origin a bit further from the entity.

[redivcram]

Blefk!

Turns out, the PlayerThink function did not work. Chose a different method of checking instead to show the output. Both is_visible and is_in_viewcone work.
