Dude, I just found out now that Castle has multiplayer. 

Wrap area and screen loop are almost the same thing, but screen loop is simpler

For some reason, the light blue box lags when going through the top and left camera areas (black border), I don't know how to fix it

Allows for the use of extra skins (In case the game has any)

Camera (screen_loop() update) + wrapInArea() (light blue box, with wrapping points). #function_blocks
