Hi all,

i have a little question.
I am working on a 2D-Engine with jogl (don’t kick me).
My problem is that i want to do levels bigger then the screen (as normal).
In 3D there is lookat(…) to set the view. Can i use glViewport(…) in 2D to change the
view to another region of the level.

I used the method to change all X,Y positions of the sprites, but this was not very efficient.
Is glViewport more efficient or is it not possible to change the view with.

can anyone give me a solution?

I think you’re looking for glTranslate() which will adjust every drawing operation afterwards by the given amount. You probably want to consider only drawing the appropriate parts of the level anyway though?
