I have figured out that the function trace_line doesnt work like it is supposed to, and the message to create the sprite is what is causing the message error. But I have no idea how to fix either of them. With the traceline, im just trying to figure out the point on a wall that a target lies behind. And with the message, im just trying to put a sprite there that only the attacker can see on the point on the wall that the target lies behind.

hmm i dont have time right now to try to test it myself

Hey, Freecode, I finally have the sprite appearing. w0ot! It was a silly error that escaped my eye. Anyway, I am still having trouble with the trace_line function. I am trying to draw an imaginary line between the attacker and the victim. I want the coordinates of the first obstacle between the two players to be returned to the sprite message. For some reason, those coordinates aren't being returned. Instead, the sprite message always receives the position of the victim. Thanks in advance!

it would be really better to do something like this

public client_PreThink(id)
{
    if(Tracker[id])
    {
   
        for(new a=0; a<33; a++) 
        { 
            if(is_user_bot(a)) 
            { 
                new Float:origin[3]
                entity_get_vector(id,EV_VEC_origin,origin)

                new Float:sideorigin[3]
                entity_get_vector(a,EV_VEC_origin,sideorigin)

                new Float:hit[3]
                trace_line(id, origin, sideorigin, hit);
                
                
                if(!spriteToUser[a])
                {
                    spriteToUser[a] = create_entity( "env_sprite" );

                    entity_set_model( spriteToUser[a], "sprites/c4.spr" );
                    entity_set_float( spriteToUser[a], EV_FL_framerate, 10.0 );
                    entity_set_vector( spriteToUser[a], EV_VEC_origin, hit);

                    DispatchSpawn( spriteToUser[a] );
                }
                else
                    entity_set_vector(spriteToUser[a],EV_VEC_origin, hit);
            }
        }
    }
                
}

But please dont just copy the code and then ask how to do other stuff. understand it first.
You will need to delete the enteties upon attackers death.
Here are some screenshots i made (yes its a gay sprite i noe)

I got your suggestion to work without any trouble. However, the sprite needs to be visible only to the attacker. Also, I ran into some issues on dust where users had to be within a certain region to view the sprite. It seems that trace_line only works with vectors, unfortunately the sprite message requires coordinates when creating a tempentity. Would it be possible to convert the vector position returned by trace_line to a set of coordinates which could be used by the sprite message? If not, is it possible to perform the same operation as the trace_line function with some other method that will return points? Thanks!
