A little contribution how to make a laser (light) targeting not using a model but bmap, which looks better I think and it's more easy to do
You can add a alpha schannel or etc

If you want to see it in action look at my "space war" project in "showcase I" section LINK
all of the others ships are using this code but only player doesn't... yet
And of'course You may change vecotr to vec_for_vertex for better looking

Code:

---

 
var my_target[3];
function laser_targeting
{
	my.passable = on; my.oriented = on; my.facing = off;
	my.flare = on; my.bright = on;
	while(you)
	{
			proc_late();
			c_setminmax(me);
			vec_set(my.x, you.x);
			vec_lerp(my.x,you.x,my_target.x,0.5);
			vec_set(temp, you.x);
			vec_sub(temp, my.x);
			vec_to_angle(my.pan,temp);
			my.tilt += 90;
			my.scale_y = vec_dist(you.x,my_target.x) / 5; //5 is the height of the bmap
	wait(1);
	}
}

action gun_action
{
	ent_create("your.tga",my.x,laser_targeting); //small one like 5x5
	while(me)
	{
		vec_set(my_target, nullvector);
		my_target.x = 500; //lighting range
		vec_rotate(my_target, my.pan);
		vec_add(my_target, my.x);
	wait(1);	
	}
}

Looks like a very good contribution , might come in handy for my current project.
