I got it to scroll finally. The only problem I'm having now is making
the scrolling stop so the player doesn't fall off the world :) The
player stops at the north and west edges...but continues to scroll,
walking off the world in the other 2 directions. Can anyone give me
some pointers? The relevant code is in the update() function (yes, i
know my update function is very inefficient...I'm trying to get it to
work before I rewrite it). Thanks for all the help.
