Sorry for the sparse updates, I haven’t been able to put as much time into this as I want, but development is still progressing. Here is a peek at the current state of enemy AI. 
As you can see, they respond to collisions consistently and flip between states of movement and idle. I used animation callbacks from dummy properties to set the duration of the behaviors in seconds, as outlined in this thread. These guys took a few iterations to get right, but the code I used is heavily reusable and modifiable, so future enemies should be a piece of cake (hopefully). Now on to making these chums into the killing machines they were made to be! (AKA pathing and attacking).
