Fog of War Demo

Hey there,
thanks for all of your hard work! I was trying this technique yesterday and got some java-script related errors after a while:.

I would be really thankfull if you would know a way to fix this. I also would try to help you as good as possible.

Edit: Also I'm trying to figure out how I can improve the black screen-size further away from the screen.

Thanks anyway! :)

Hello, how to have "square" cells and not round cells ?

For instance, to use in a tiled strategy game.

Thanks
