The animation system is done! Probably a bit more complicated than it should be but that's fine. Animations are defined using a byte-code similar to what the sound system uses for music and sound effects. However to facilitate jumping into the middle of an animation sequence each byte-code instruction has a time stamp indicating how many frames into the animation it should be executed at. Currently it can only modify an object's current sprite but it can easily be extended to modify all of an object's properties and possibly do additional things such as creating particles or spawning new objects.
And as noted on that page my next goal is probably going to be to make some actual tools for content creation. Currently I only have a small python script to convert .PNG images which works well enough, but I have some fairly complicated data formats. Putting these together by hand in a hex editor is a very time consuming and error prone process and that simply won't do if I want to actually have some decent content in time for the jam.
However one other thing I did today was package up some test builds! They aren't terribly exciting as there's nothing to actually do in them just yet, but I do need to make sure that they actually run for other people. So make sure to check them out and let me know if they have any problems.
