Are there any sort of standards for encoding tile based maps. I know javanerd told me about his RIFF encoding one time, and i was wondering if there are other ''standard'' formats or if game developers usually develop their own based on each games specific needs. I guess it would depend heavily on my map object and what sort of fields and methods it has; not to mention the tile objects themselves. I guess I''m looking for a little direction as to how to structure my map ''model''. It''s standard overhead, no isometrics
