# Help with game of life on 8*10 LED matrix

Hi,
I have made a 8*10 LED matrix and I wanted to run game of life on it.
I have tried to use the code from Direct driving of an 8x8 LED matrix by Andrew. I have done all of the needed changes for it to work, but I got stock in this part:
This is the part that deals with the 4 rules. and SIZE = 8
but I have 2 sizes 10 and 8, and I don’t know where to put what.
int neighbours(int x, int y) {
return world[(x + 1) % SIZE][y][0] +
world[(y + 1) % SIZE][0] +
world[(x + SIZE - 1) % SIZE][y][0] +
world[(y + SIZE - 1) % SIZE][0] +
world[(x + 1) % SIZE][(y + 1) % SIZE][0] +
world[(x + SIZE - 1) % SIZE][(y + 1) % SIZE][0] +
world[(x + SIZE - 1) % SIZE][(y + SIZE - 1) % SIZE][0] +
world[(x + 1) % SIZE][(y + SIZE - 1) % SIZE][0];
}

So if some one can help me with that I would be very happy.
Thanks.

Off the top of my head - define two different size constants, XSIZE and YSIZE. Then where my code is applying SIZE to “x” replace it with XSIZE and where it’s applying size to “y” replace it with YSIZE.

Be sure to post pictures/videos of it working!

OK thank you very much. I tried it and it works :D, I will post a link to a video on youtube very soon.

Thanks again for the fast reply.

So here it is working : http://www.youtube.com/watch?v=6DQAn-Rqhpw Thanks again for the help.

You've made a neat job of that, very nice. I wish my hardware skills matched my software.
