Simple Tiled Implementation

If you like STI, consider tossing me a few monies via PayPal.

Simple Tiled Implementation is a Tiled map loader and renderer designed for the awesome LÖVE framework. Please read the documentation to learn how it works, or check out this handy tutorial I wrote! The tutorial might be a bit out of date so be sure to check the documentation if there are any issues.

Quick Example

-- This example uses the included Box2D (love.physics) plugin!!

local sti = require "sti"

function love.load()
	-- Grab window size
	windowWidth  = love.graphics.getWidth()
	windowHeight = love.graphics.getHeight()

	-- Set world meter size (in pixels)
	love.physics.setMeter(32)

	-- Load a map exported to Lua from Tiled
	map = sti("assets/maps/map01.lua", { "box2d" })

	-- Prepare physics world with horizontal and vertical gravity
	world = love.physics.newWorld(0, 0)

	-- Prepare collision objects
	map:box2d_init(world)

	-- Create a Custom Layer
	map:addCustomLayer("Sprite Layer", 3)

	-- Add data to Custom Layer
	local spriteLayer = map.layers["Sprite Layer"]
	spriteLayer.sprites = {
		player = {
			image = love.graphics.newImage("assets/sprites/player.png"),
			x = 64,
			y = 64,
			r = 0,
		}
	}

	-- Update callback for Custom Layer
	function spriteLayer:update(dt)
		for _, sprite in pairs(self.sprites) do
			sprite.r = sprite.r + math.rad(90 * dt)
		end
	end

	-- Draw callback for Custom Layer
	function spriteLayer:draw()
		for _, sprite in pairs(self.sprites) do
			local x = math.floor(sprite.x)
			local y = math.floor(sprite.y)
			local r = sprite.r
			love.graphics.draw(sprite.image, x, y, r)
		end
	end
end

function love.update(dt)
	map:update(dt)
end

function love.draw()
	-- Draw the map and all objects within
	love.graphics.setColor(255, 255, 255)
	map:draw()

	-- Draw Collision Map (useful for debugging)
	love.graphics.setColor(255, 0, 0)
	map:box2d_draw()

	-- Please note that map:draw, map:box2d_draw, and map:bump_draw take
	-- translate and scale arguments (tx, ty, sx, sy) for when you want to
	-- grow, shrink, or reposition your map on screen.
end

Requirements

This library recommends LÖVE 11.0 and Tiled 0.18. If you are updating from an older version of Tiled, please re-export your Lua map files.
