How to use AddTransition in two different TStateId based by enum?

[sandsalamand]

You can't transition from one enum type to another within the same StateMachine. You're trying to transition from a MoveState to a JumpState, but moveFsm was defined as a StateMachine<PlayerStates, MoveStates, Events>, with the second T parameter, MoveStates, showing that moveFsm will only allow transitions between MoveStates. The first T there, PlayerStates, is only applicable if you're nesting the state machines.

See on the line fsm.AddState(PlayerStates.MOVE, moveFsm);
They're adding moveFsm to fsm as a nested state machine. This is possible because moveFsm had <PlayerStates> as its first parameter, meaning that you're allowed to nest it under fsm which transitions between PlayerStates.
