Infinite wave creation problem

[Norishou]

1. When finished creation of the first wave look if all enemies are gone

2. If all are gone increase the amount of Enemies by two and start the for look again

3. If not all are gone make a small delay and look again

   PS: Delay does only work in loops if you create a macro (try doing this Unreal Engine 4 Tutorial: For Each Loop With Delay - YouTube)
