GC FSM - Event-driven, hierarchical finite state machines in blueprint

[gamecentric (Alberto Barbati)]

I ended up creating a base FSM class with a nested state machine that switches between doing nothing and the “from any state” behavior (in this case, a pause menu), then using that as the parent for my main interaction modes, so that every interaction mode can be “interrupted” by the modal menu and then return to its normal operation when it exits the modal menu substate. Seems to work fine so far. Great plugin!

That is very clever. Thanks for the use case, it seems very legitimate. The best tool to address this scenario would be to add support for a feature like the “history pseudostate” in UML. I’ll add it to my todo list.
