Disable signal animation after first occurence

silly-little-kee

Hi there,

I recently started messing around with Godot and decided to learn it in order to make a simple 2D plateformer.

In short, I'm very nooby at it at the moment so don't bite me!

I have a very simple signal setup where a static body move upward a bit when the player enters an Area2D collision. (Thanks to an AnimationPlayer node attached to the static object).

It works well but everytime the player enters the Area2D, it repeats the animation.

Is there a way to disable the signal once triggered?

I guess there's a better way to achieve this than using the AnimationPlayer node?

My noobish code is as follow:

extends AnimationPlayer

func _on_Area2D_body_entered(body):
	play("Lift")

Regards :)

One possibility is to add a handler function for the "animation_finished" signal, and in that handler call remove_animation("Lift"). Check that has_animation("Lift") is true before calling play("Lift").

This is theoretical. I haven't tried it.

When connecting a signal (in the Connect a Signal to a Method window) there is Advanced toggle switch. Turn it on and enable Oneshot checbox that showed up. This will ensure the signal is automatically disconnected after it has been called once.

Amazing, thank you :)
