Hillmix

Hillmix is a useful tool for 2D games or other projects based on Box2D, before you get to coding. It helps easy to edit game levels and physics. Select folder with images that will be used for a project. Place images as bodies on scene. Draw bodies shape as rectangles, circles, polygons, polylines and set up physical properties of each object. Save that all to JSON format. Use saved file and any engine or programming language that fits best for your game in order to bring it all together.
