Look in the Library folder.
You'll see GraphXXXX.dat files.
(The XXXX is a stand in for the different names of the dats.)
You can't miss them.
Those tell you how things work.
Then check the different parts of the Sub files for StateMachine controller.
I don't remember which file at the moment but it's there somewhere.
I've not messed with them yet so that's all I can tell you at this time.
DivingDuck or Anvart could explain more but both are away at this time.
