Im planning to develop a game which will require numerous TiledLayers (around 3 or 4) for rendering. This means that most tiles in many layers will be fully transparent (tile index 0). I suppose TiledLayer.Paint() looks something like this:
So for each TiledLayer this double loop will be executed each frame although blitTile() will only be executed a few tiles since most tiles are transparent. My question is: Will this generate a performance overhead - or is the cpu needed for the loop negliable as compared to the blit operations? If this is an overhead, could i increase performance by not using TiledLayers and instead blit a list of tiles for each layer using Sprite.paint(), Graphics.drawImage(), Graphics.copyArea(), Graphics.drawRGB() or something like that? Or is TiledLayer somehow magically optimized?
Nice forum by the way, first post for me here. Peace!
