Tiled Map Editor

Here you will find various resources to help you create games and apps in Gideros Studio.
note: you may have to provide your own assets (fonts, gfx, …)

Description

On this page you will find various classes to help using Tiled Map Editor in Gideros. Enjoy :-)

Tiled Map Editor

LOAD YOUR MAP

Here is a class to load your Tiled map in Gideros.
note: world is used for Box2D (LiquidFun) or CBUMP but you can remove it and adpat to your needs

LevelX = Core.class(Sprite)

function LevelX:init()
	application:setBackgroundColor(0x0)
	-- the tiled world
	self.tiled_level = Tiled_Levels.new(self.world, "tiled/levels/level01.lua")
	self:addChild(self.tiled_level)
end

Below is the Tiled_Levels class.

BUILD YOUR MAP

Here is the class to import the levels your created in Tiled and draw them in Gideros using the RECTANGLES, POLYGONS, ELLIPSES classes you will find further below on this page.
note: don't forget to exclude from execution your level lua file (right click -> exclude from execution)
note2: those are placeholder names (bg = background layer, mg = middle ground layer...) adapt to your needs
