How about using numeric to calculate the coordinates
for each tile? I think that is one of the slow bits.
So a move right by ten pixels would be something like
tile_positions + (10,0). Then pass slices of the
array to a c drawing function. The slice would only
be of the tiles which are to be drawn.
If you have a massive map( 1000's of tiles accross ),
then you'd want to only update the positions of the
viewable tiles(again by using a slice of the visible
tiles). So you'd have a visible matrix of tile x,y
positions, and a full map matrix which consists of the
type of tile to be drawn(an index into a list of
A similar method should also be useful for drawing
lots of sprites or particles, as you don't have the
python object overhead for each sprite.
I don't have the time to implement it now though :(
Someone else who thinks it'll work wanna do it for us?
