Code:

---

function c_ship
{
	player = my;	
	my.scale_x = 1.0;
	my.scale_y = my.scale_x;
	my.scale_z = my.scale_x;
	while(1)
	{
	     c_scan(player.x, temp, vector(360, 60, 1000), ignore_me);	
	     wait(-0.25); // we musn't scan every frame; c_scan is too slow for that	
        }

}

I just took out the IF statement and put in a larger wait value. It scans permanently every quarter second. See if that's more like what you're looking for?
