Quite a bit more progress on the Emergence engine, PhysX materials have been implemented, the map doesn't have materials yet, but that won't be that big of a deal. Skyboxes have also been implemented, at least to some degree though certainly not final. The AI systems has been significantly advanced. I have decided to create an AI system that will work with both Lua scripts and an external dll file, that way really simple items that don't require much processing power can be run with Lua scripts, and heavy AI objects can be processed with machine instructions, which will be much faster. I'm thinking simple items like doors or simple entities (that only need to play sounds, or other small matters) can be run by Lua scripts while complex AIs that follow graphs and do other intelligent things can be run by machine code. The AI system, however, will be developed so that Lua scripts can do everything that machine code can do, only slower.
