    TileMap enhancement

    edited June 2012 in Suggestions & requests
    It would be good if the top bits of a tilemap (16-bit block numbers) could be used to tell the renderer to:

    H-Flip
    V-Vlip
    Rotate by 90 degrees

    These 3 bits could be used by a proper map editor to save loads of tilespace.

      Another enhancement would be a block number that is not drawn.

      This would allow overlayed/layered maps to be more rapidly drawn.

      I think using block number 0 in tiled will give you that effect

      techdojo: Thanks, will have to check that out...

      Now it just needs the h,v and r bits. :)

      @SinisterSoft I've implemented horizontal, vertical and diagonal flips. it will be available with the next version. I'm attaching a screenshot of the test case.

      Will there be a document saying what bits do what, also could you confirm that block 0 will not be drawn.

      I'm in the process of making a map editor for my game you see.

      @atilim: Seeing as you have been playing with TileMap, have you looked into isometric maps yet :) (squeaky wheel get the oil and all that)

      With regards "block 0" not being drawn.
      It's supported by just not adding that tile to the map.

      ie. (code from @Atilim's simple Tiled map reader)
      TileMapSingle = Core.class(Sprite)
 
function TileMapSingle:init(map)
	-- local map = loadfile(filename)()
 
	local tileset = map.tilesets[1]
	tileset.sizex = math.floor((tileset.imagewidth - tileset.margin + tileset.spacing) / (tileset.tilewidth + tileset.spacing))
	tileset.sizey = math.floor((tileset.imageheight - tileset.margin + tileset.spacing) / (tileset.tileheight + tileset.spacing))	
	tileset.texture = Texture.new(tileset.image)
 
	local layer = map.layers[1]
 
	local tilemap = TileMap.new(layer.width, 
								layer.height,
								tileset.texture,
								tileset.tilewidth,
								tileset.tileheight,
								tileset.spacing,
								tileset.spacing,
								tileset.margin,
								tileset.margin,
								map.tilewidth,
								map.tileheight)
 
	for y=1,layer.height do
		for x=1,layer.width do
			local i = x + (y - 1) * layer.width
			local gid = layer.data[i]
			if gid ~= 0 then
				local tx = (gid - tileset.firstgid) % tileset.sizex + 1
				local ty = math.floor((gid - tileset.firstgid) / tileset.sizex) + 1
				tilemap:setTile(x, y, tx, ty)
			end
		end
	end
 
	self:addChild(tilemap)
end
      To erase a tile use the TileMap:clearTile(x, y) function.

      @Scouser After some tests, I understood that supporting isometric maps is easier than I expected. Adding a single function to TileMap will be enough as:
      tilemap:setOrientation(TileMap.ISOMETRIC)  --> render tile map as isometric
tilemap:setOrientation(TileMap.ORTHOGONAL)  --> default, render tile map as orthogonal
      I'll try to implement it as the next version.
