Any help to start an animation?

Hello, could someone tells me how to start a fadin animation of my background triggered from that script, changin scene with the fadin.

Get a sprite with a pure black texture. Extend this sprite to cover the screen, and ensure the sprite's Z is high enough to cover everything you want it to. Use a singleton for easy access to the fader node which changes the opacity of the black sprite over time, alternatively couple the fader with the scene changer. Animating the fade can be done in code, such as with a lerp and perhaps a timer, or it can be done with an AnimationPlayer node.

When the animation is done, emit_signal("FaderComplete"), or use the AnimationPlayer's animation_finished signal, now your scene changer knows it's OK to swap scenes.

Once that's done, emit_signal("SceneChangeComplete") Then make the opacity of the fader 0 again, using your method of choice, thus completing the fade.

You don't need a sprite to represent a solid color, just create a ColorRect node (ColorFrame in 2.1) instead :)

By the way, you should use TextureRect (TextureFrame in 2.1) instead of Sprite for GUI purposes, as Sprite inherits from Node2D whereas TextureRect inherits from Control.

Didn't know there was such a node, thanks for the heads up. Out of curiosity, what is the real difference between using a Node2D and a Control when it comes to a fullscreen fade?

Ok, it's done, thxs you all!
