Ok, then I suggest you try c_move.

This code works:

Code:

---

...
ent_create ("bullet.mdl", my.x, bullet_behaviour);
...

function bullet_behaviour() {
	var covered_distance = 0;
	
	vec_for_angle (my.x, you.pan);
	vec_scale (my.x, 10);
	vec_add (my.x, you.x);
	
	vec_set(my.pan, you.pan);

        //we need to store the you (parent entity) because it will be emptied after the next wait(1)
	ENTITY* parent_ent = you;
	
	while (me) {  
	  you = parent_ent; //search back for the parent entity
	  covered_distance = c_move (me, vector(40 * time_step, 0, 0), nullvector, IGNORE_YOU); //move 40 quants ahead and ignore the parent entity
	  
	  //bullet is stuck on impact, do possible damage and remove
	  if (covered_distance <= 0) {
	    you = c_trace (target.x, target.x, IGNORE_ME); //search for the entity hit
	    if (you) {you.health -= 5;} //If theres an entity, remove health. or whatever you had in mind ;)
	    ent_remove(me); //ptr_remove(me) if you have the newest version
	  }
	  wait(1);
	}
}
