Re: [pygame] Big Tile Maps

[Phil Hassey <philhassey@xxxxxxxxx>]

Sw,

My pgu library does pretty good for overhead games. 
There is no slowdown for very large maps.

At the very least, take a look at the code in
pgu/tilevid.py and see the update() and paint()
functions for how I do it.  I only draw on screen the
stuff that needs to be drawn.
