First of all I'm really new to this scene. I know Java, but hardly know OpenGL / Game Development.
Today I spent a lot of time reading several tutorials about libgdx.
Now I wanted to create an effect that looks like this:
I got 2 players and a simple background image.
Now I want to use these players as alpha map for my background.
So the players could move, but the background does not move.
Like an "inverted" world.
Do I have to use the stencil buffer for this?
Or may be there better options?
Is it just a simple (combined) alpha map?
Hope you can help me!
