# X/Y_Movement_Of_Connection

|
#~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
#
|
|
# A X movement is how many map blocks there are to the left of one of your north/south connections.
|
|
# A Y movement is how many map blocks there are above your west/east connection.
|

# This points to the part of the current map (further up in RAM)
|
|
# that the connection strips upperleft block is placed on the current map.
