Hello,
I tried your demo 07_tiled_tmw_with_renderer.py with another tmwa map (002-1.tmx).
It works but I can not move the avatar.
My engine derived from your demo can not show the avatar at all.
I think it depends by the layers number which is 8, and not 6 as in 001-1.tmx, but I have tried to change all the variables to manage the new layers number and something seems still to be wrong, I can not understand what.
