Ok, i know C++ fairly well, and i know some openGL as well. Now, i decided to try to make a tetris clone, and im not quite sure how to do it... Does anyone know where i can find a tutorial on how to make tetris with c++ and opengl? "Google"...No i tried doing a search on google, but i didnt find anything...
