Show pickable tiles

[henqqq]

this is a simple HUD that shows pickables tiles
p.s: I used some functions from ShowSpecialAreas HUD.

init start

	

local worldWidth, worldHeight, x, y, z, width, height, avoidance, name, policy, areaType

	local specialAreaRect = {}

	local innerRect = {}



	function gettilepos(x, y, z)

		local tile = getobjectarea(x, y, z)



		if tile == nil then

			local xDiff, yDiff = x - $posx, y - $posy

			if math.abs($posx - x) <= 7 then

				tile = getobjectarea(x, $posy, $posz)

				xDiff = 0

			elseif math.abs($posy - y) <= 5 then

				tile = getobjectarea($posx, y, $posz)

				yDiff = 0

			else

				tile = getobjectarea($posx, $posy, $posz)

			end



			-- Some strange stuff happens when you go from 0 to -1, so I'm

			-- adding this as a precaution.

			if tile ~= nil then

				local width, height = $worldwin.width, $worldwin.height



				tile.left    = tile.left    + (width * xDiff)

	local function getAreaRect(x, y, w, h)

	end

			setfillstyle('color', 0xFF000000)
