just imagine the enemy ( which is the predator ) isn't a ship but a bullet, make it much faster then the player, then the yellow spot is your leading point to fire. Short: adjust the speed-ratings to your laser,bullet,rocket and ship speeds, so add ship-speed to the bullet speed and let your gun fire at the yellow point in a straight line and thats all about it. As with every interception you must be faster then the target and the target should travel at a straight line for best results, with a little tweaking you should be fine.
