UPDATE: There is a newer, better version from here. Thanks, Zach Musgrave!
So yesterday I came across a very basic loader for Tiled Maps (*.tmx) made with the Tiled Map Editor. It only supported the basics–Tileset loading and Layer rendering–so I took it upon myself to complete the loader by adding support for the rest of the features that were left out;
-added ProhibitDtd = false, so you don’t need to remove the doctype line after each time you edit the map.
-changed everything to use SortedLists for named referencing–so much easier
-added movable and resizable objects
-added object images
-added meta property support to maps, layers, object groups and objects
-added support for non-binary encoded layer data
-added layer and object group transparency
I created a simple demo to show off some of the features. You should see a partially transparent object with a resized image of Ness (Earthbound) on top of a partially transparent layer of grass with the words “Tile Maps Rule” written in rock with a pulsating opacity. Use the arrow keys to move Ness around. All objects and object groups can have their X and Y coordinates set dynamically, so you can do cool stuff like parallax clouds drifting overhead.
