It's a simple project which you can use for multiplayergames. The red point are you, the blue points are the others.There are three cloud lists: x-positions, y-positions, and usernames. If there aren't enough users online, you won't see any blue points.
The basic is the cloud-list project of relrel(scratch.mit.edu/users/relrel). You always can use it, but please tell the public in the "Thanks" and give me a like. ;-)
