that scrolling can be modified to be more like zelda scrolling. when you get to the edge of the screen, instead of going directly to the new screen center, you can stop everything else, scroll the center of the screen to the new one then release everything again.
a bit more complex and requires you to activate and deactivate groups. also recommended you not use any built in movements. otherwise youd have to stop all movements as well. then start them again appropriately.
yeah im always afraid to use that cause of the division. ive done things like that before (snap to grid) and it didnt quite work for some reason. i hate how mmf utilizes floats. i dont even bother anymore.
