What's the physical moving of wrapping should be?
For example, I could set logical position wrapped from (0,9) -> (0,0) in 10x10 board.
But what is the physical moving in this case?
step1. move from (0,9) to boundary of (0,9) and (0, 10)
step2. set position to boundary (0,-1) and (0,0)
step3. move to (0,0)
