I decided I was far enough along on Chum to put it up on github:

http://github.com/jslade/chum

It’s far from complete — I’m really just working on the proof of concept now: will it be reasonably easy to use to build a full game, and will it perform decently for some relatively simple stuff out of the box?

But so far, I am pleased with how it’s coming together.  I have liked several things about using the tree of GameNodes for everything, with GameEvents to manage communications between nodes.  I recently added GameSequence, which makes use of both.  It’s intended to be the basis for managing animations and such — I already used it to implement several text animations, as shown in the AnimatedTextExample:

                // Shake side to side
                animation = new GameSequence.Series();
                int offset = FP.intToFP(30);
                to.set(center);
                from.set(center);
                to.x = center.x - offset;
                animation.addNode(textNode.animatePosition(from,to,50));
                from.set(to);
                to.x = center.x + offset;
                animation.addNode(textNode.animatePosition(from,to,70));
                from.set(to);
                to.x = center.x - offset;
                animation.addNode(textNode.animatePosition(from,to,70));
                from.set(to);
                to.x = center.x + offset;
                animation.addNode(textNode.animatePosition(from,to,70));

xI hope to be working on a couple of actual games using Chum in the near future — a 2D game called ‘Misma‘ ported from the iPhone, and a simple 3D action game along the lines of ‘3D Cube Race‘,  but with a lot more to it.  And I’ll be at Google I/O in a couple of weeks, and would be more than happy to talk about Chum, game engines, games in general, or whatever…
