Tilesets & RPG maps

Here, this is how i have done it:

	'Draw map
	For Local layer:Int = 1 To 4
		DrawLayer(World, WorldX, WorldY, WorldZ, layer, player.x, player.y) 
	Next
	
	'Draw player
	player.Render(Int(player.x * tween + player.tx * (1.0 - tween)), Int(player.y * tween + player.ty * (1.0 - tween))) 
	
	For Local layer:Int = 6 To 7
		DrawLayer(World, WorldX, WorldY, WorldZ, layer, player.x, player.y) 
	Next

	'code goes here if player happens to be standing on a bridge (2nd level)

	For Local layer:Int = 9 To 9
		DrawLayer(World, WorldX, WorldY, WorldZ, layer, player.x, player.y) 
	Next

talking about it, i also want to add shadows. that would give me another bunch of layers :S



the problem is tough, that the trees are part of the background, so i cant render shadows dynamicly.
Anyway, i will also have movable trees, these are objects.
