It's all pen. You can drag the grid and pause. Basically the laws of this game are white squares in the grid are dead, and black squares are alive. If a black square has 2-3 neighbors, it lives. If a black square has less than 2 or more than 3 neighbors, it dies. If a dead square has three neighbors, it lives. After clicking "Pause," clicking "Next" will just run the very next frame instead of just running the whole thing. P.S. The squares were not harmed and are all living a happy life. This is just a simulation. ;) ------le credits------ Text engine from @caders_117 @xamuil2 for most code ------le credits are done------ BYE! See you next time.
