Hi everyone, i'm new in game developing. Recently i programmed my first game, a pong game. I used c++ with opengl. The game works very well, but now i want to improve my desing. I don' t know what is de common way to do this, but the general idea is change the quads i've made with opengl (for the ball and the rackets) by 2D sprites i designed.

 

I don't know if this kind of things can be done with opengl. I need specific libraries or toolkits? And one more question, can i make a GUI with sprites as buttons?

 

Thanks a lot! biggrin.png

sprites are nothing more than a quad with a textured drawn on top of it.  By using the alpha channel in your texture you can make objects looks like spheres or characters even though the underlining geometry is still two triangles.
