LIGHTS_OUT_OPENGL
OpenGL version of "Lights Out"


LIGHTS_OUT_OPENGL is a C program which sets up the "Lights Out" game and allows a user to try to solve it.

The Lights Out game is played on a rectangular board of squares, each representing a light that may be on or off. Clicking the mouse on a light switches it from on to off and vice versa. However, when you switch a light, you also switch the lights to the immediate left, right, above and below. (There is no "wrap around" however, in this basic version of the game.)

You start the game by specifying the width and height of the board to be used, and the number of moves the program should make in setting up the inital board. Specifying 10 moves, for instance, means that the program, starting from a board with all lights off, will randomly switch a light and its neighbors 10 times.

Usage:

lights_out_opengl width height moves
