# 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()
}}}
