Quick Question: Tracing and stuff

Hey guys,
I'm a bit confused about something and I was just wondering how I'd make this code scan in front of the object instead of downwards:
Code:

---

 
// detect walls infront of the user
function proj_scanfront(scandist)
{
	// scan and store data into a local
	var scanstore;
	c_trace(my.x, vector(my.x, my.y, my.z + scandist), ignore_me + ignore_passable + scan_texture);
	
	// reposition at the target
	vec_set(scanstore, target);
	vec_set(my.x, scanstore.x);
}

Its suppost to be for a player shooting a weapon.
Thanks for your interest and I hope to hear from you soon

Code:

---

function proj_scanfront(scandist)
{
   vec_set(temp,vector(scandist,0,0));
   vec_rotate(temp,my.pan);
   vec_add(temp,my.x);

   c_trace(my.x, temp, ignore_me + ignore_passable + scan_texture);	

   // reposition at the target
   vec_set(scanstore, target);	
   vec_set(my.x, scanstore.x);
}
