How to spawn in waves of enemy?

Hello,
I’m french so sorry my English. I have a question for my project …

  1. How to spawn enemy waves?

  2. How to make the enemy come to destroy the tower?

Thanks you !

There is nobody?

I highly recommend all of the tutorials from this series, but in particular, you’re going to want this one:

They are for UE4.8, but I’ve made them work on 4.12 and 4.13 with no problems.
