graphics - How to restart screen in openGL? -


i have developed simple program in opengl. @ first when click on ball goes above want when press 's' in keyboard ball should in initial state.i want reset tx,ty values. otherwise program changes don't come previous state. it's restart new game.

hard tell more without seeing code.
