I would suggest that, as soon as you spawn a new enemy, you check to see whether it is colliding with another enemy. If so, simply move it to another place and check it again. Keep doing that till it’s not colliding with any others. Make sense?

I’m making another game based on this and can’t figure out a solution to stop enemies from spawning on top of each-other. Got any ideas? I have tanks and other vehicles as the enemies and it doesn’t look very realistic when they are stuck together.

In a way, yes, that’s what we’re doing. Think of variable names as being temporary; they’re like post-it notes. Earlier, when you created the enemy, you stuck a post-it note to it that said “newEnemy”. When you created another enemy, you basically removed the post-it note from the first enemy, and stuck it on the second – so the first has no name.

That for-each loop goes through every item in the army[] array, one by one. The first enemy it looks at, it slaps a post-it note on it that says “enemy”. This means that any code inside the for-each loop will refer to that specific enemy, the one with the post-it note. At the end of the for-each loop, it takes the post-it note off that item and puts it onto the next one, and so on and so on.

Hope that helps clear it up!
