I'm not a coder so I can't really do that. I'm not sure how much you can actually do but I've noticed some things missing that would come in handy.
For example:-
It looks like there aren't any actions with check boxes for checking every frame or even defining a set amount of frames to keep checking.
there are also check actions but not change or get actions for some things like speed.
Also, is there a possibility to store combatant prefabs in an array?
This is all I can think of right now. Still having a lot of difficulty implementing a controller for a top down game and I have to wait till Gil gets back I guess :/
OK hope these help. I was thinking about them as I browsed the actions and thought it might be a good idea to tell you.
