Level wrapping Edit
Level wrapping causes an object moving outside the level to appear on the opposite side. A popular example of this is Pacman. This can be easily implemented by surrounding the level in some kind of
Border object and then using the following rule:
[ Border | < A | ... | | Border ] -> [ Border | | ... | A | Border ]
A object wanting to move into a
Border object will be removed and placed adjacent to the nearest
Border in the opposite direction.
