So I have a website, and I wanted to make 2D multiplayer games for it. It's a simple concept; you have a circle and click to walk to a place (if you've ever heard of Socialmeeps you might know). I have almost all things done, but I have no idea how to make players see each other. I've read all the tutorials multiple times, and I really don't know what I'm doing. It's at the point where I'm trying random things that I know won't work.
If anyone could help me, I'd be very grateful!
