Missing: Adaptation of code for 3 more enemies Note: Should asteroids kill enemies? Note 2: Original script makes enemies move in a wave-like motion, trig real life application Note 3: If enemy waves are to be repeated, "wait until x=x1 or y=y1 or z=z1 or ad infinitum" block should be used to trigger the enemy, instead of using message triggers, so the value from different variables should be changed to trigger enemy.
