Set a non-alien active object (after this called the control object) flags on if the aliens are going left, and off if they are going right. Have every 00.02 or so, set alien's position depending on the flag example Set Alien X position to X(Alien)+2, and reverse for going left. Then when the alien is far enough left of right, set the flag to the appropiate value. (do not use aliens as control object, as this will only set the flag of the alien turning)
Now this will only let the aliens move left and right. Now to make them move down, we can use a value. Add "value a of (control object) = 0" to the events for the aliens movement. Create a new event, every 00.04 "value A of (control object) > 0" and add actions for moving the alien down, Set Alien Y position to Y(Alien)+2, and substract 1 from (control object) value A. Finally, add an action to set this value to 45.
Now try it, and mess a little with the additions/substractions for Alien's position, timing and stuff. Get it to your liking.
- Ok, you must admit that was the most creative cussing this site have ever seen -
Make some more box arts damnit!
