How to use

• Add a Node2D node named "StateMachine" with the script state_machine.gd
• Initialize the states, initial state and conditions:

	$StateMachine.add_state("idle")
	$StateMachine.add_state("hurt")
	$StateMachine.add_state("dead")
	$StateMachine.set_init_state("idle")
	$StateMachine.add_transition("idle", "hurt", [], "fire")
	$StateMachine.add_transition("hurt", "dead", ["has_stuff_been_handled", "is_dead"])
	$StateMachine.add_transition("hurt", "idle", ["has_stuff_been_handled"])

• Trigger an event

	$StateMachine.trigger("fire")

• Add a condition: it's just a func returning a bool

    def has_stuff_been_handled():
        return true

• Add callbacks for state entering/update/exiting: just add the state name in on_XXXXX_state_YYYY()

    func on_idle_state_enter():
        pass

    func on_idle_state_update(delta):
        pass

    func on_idle_state_exit():
        pass

• Enabling debug mode (logs when changing states)

    $StateMachine.set_debug_enabled(true)

• Get the current state

    $StateMachine.get_current_state()

• Get the last known state (before the current one)

    $StateMachine.get_last_state()
