Thats exactly what I am doing. There is a central login point where coordinates are emitted to all clients. But some funny reasons I can't explain they won't just align. A simple test was to move one of the players directly over the other and left it there. It appears so on the first screen, but on the second, it was few pixels away from it.
I am working on a multiplayer space shooter game. This works fine, but when the players are on different screens, their respective positions differ from each other in few pixels. How do I ensure the objects align across players/screens.
