I haven’t posted here in quite a while, so I think it’s time to catch up on the plans for twig. The main issue is that I’ll be teaching a class in the fall using Twig, so I’ve been working to make it easier for people who aren’t me to build new behaviors in the system by both refactoring codebase and building in a real scripting language (based on Scheme), along with a reimplementation of the behavior-based programming infrastructure we used to use in my lab for robot programming.
So suffice it to say that we’re close to the point where I’m ready to do a 1.0 release (we’ve been at 0.2 for a while). We have tools for authoring new motion behaviors in the scripting language, along with interactive in-game debugging. I’ll also be doing a simple behavior-tree implementation based on Chris Hecker’s BT system for Spore. Classes start in mid-september, so that will be my forcing function for putting up a 1.0 beta release, and then we’ll probably have new bug fix releases every week or so after that.
