Hi i have a video game shield; Video Game Shield | Wayne and Layne. And am using it with the libraries on that web site. Now I took the example snakes modified it but what ever i did i could not get the maps to work, it would just automatically, no matter what I chose, run the regular map.

Please help,

Why does your code start with an opening block comment? Does that even compile?

oh sorry that was a fluke it shouldn't be there

hadjisra:
oh sorry that was a fluke it shouldn't be there

So, you going to post the code you're actually compiling and running? What does 'map' mean in this context? I don't see any mention of maps in your code.

ok well for the original demo it statrs by saying snakes on a surface connect p1 and p2; p1 ready, p2 ready. press c to start i press c then it says; Available maps; plane, sphere, torus. Now no matter which I chose the map is always plane
