To have a series of different enemy waves, all we need to implement is a different enemy with a different wave pattern.
We don’t need to redo the Spawn system. We need to adjust the animation of the enemy. To do that, we need to take our current enemy wave 01 and create an enemy 02 option out of it.
For the enemy waves, we need to swap the enemy prefab with a new enemy prefab with a new animator AND animation.
Then choose the correct spawn rate and total enemies to spawn. So simple!
