The godot documentation has a pretty good document about 2d animation, here : https://docs.godotengine.org/en/stable/tutorials/2d/2d_sprite_animation.html
It seems like if I have a sprite sheet, I can user either AnimatedSprite -OR- AnimationPlayer to work out the various animations.
If I am using Individual Images (1 image / per frame) I can use Animated Sprite.
What I am trying to do is the one case not really described here - use individual images but with animation player. Mostly, because the Animation player seems to have a lot of other cool functionality that spriteFrame do not.
Is this possible?
