Since releasing the demo, we are heavily working on the REVERT3D scripting frontend. It will feature an integrated script editor which can be accessed from within the map editors. It features a simple but (hopefully) yet useful editor with syntax highlighting, function browser and complete API reference. The screenshot to the lower left features the current version, which is just working not bad to this point. To test the whole mess, we're currently translating all of the demo code into the scripting language (which is Lua, BTW). You can see some portions of the door code in the screenshot.
We also did a lot of improvements on other parts of the engine like completing the load/save menu for the map editors and adding some eyecandy to the 2D map view - It now displays the floor textures, making it easier to locate specific map regions when working in 2D.
