1  Game Development / Newbie & Debugging Questions / Re: Do I need the stencil buffer for this? on: 2013-08-24 15:39:40
Thanks RobinB, I will take a closer look at the FrameBuffer.

And as soon as I add this line:
Gdx.gl20.glBlendFuncSeparate(GL20.GL_ZERO, GL20.GL_ONE, GL20.GL_SRC_COLOR, GL20.GL_ZERO);

I get a NullpointerException.

Any ideas? :/
2  Game Development / Newbie & Debugging Questions / Do I need the stencil buffer for this? on: 2013-08-23 18:32:00
Hey all!

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!
