Could you kindly add the option, perhaps via a checkbox or a simple toggle, that allows the camera to stop when the player reaches the edge of the room, preventing it from showing the empty space outside the room? I keep writing the code manually for this, but it would be extremely convenient to have this function built-in. This way, we could simply use the room settings for the camera, instead of having to manually create a custom camera or viewport for each game.

Does changing the room size increase the memory used or make the game size larger?
