Really I have not looked into any project, I just toke a base from the couch knights example available on the marketplace and started thinking what I would like to do.
You just need to think on the easiest and most escalable way of doing what you want.
Handkor:
Like its an online game, Im doing it all in the event Tick on the character BP, really Im only handling it with some booleans and some “play anim montage” nodes.
So there is no real “communication”, just the variables are beign taken on the anim blueprint, nothink more (and a minor cast from the anim bp to character bp, but are just for one special case)
So finally I have 1 cast on the anim BP to take variables from the character, and another cast to character BP to call a function.
Hope it helps
