Calculating RenderTexture fill percentage with masks

Phaser 3
1

Hi there!

There is this scratch example.
What I’d like to achieve is to tell what percentage of the masked shape is already scratched off at any given time.
How could I do this? What kind of data do I have here to work with?

Thank you for your answers in advance!

You can do this with a CanvasTexture. I would copy and scale it to a second texture and count that because the counting takes a while.

If you look at RenderTexture#snapshot you can probably copy that to a canvas as well.
