Well, the Iso3D World Editor is starting to shape up, after i found a stupid bug (dealing with not setting a pointer to 0 on initialization). A screenshot of the (not quite finished) world editor is attached.
MadsG also had the idea that the "walking" animations should be timed in game-units rather than screen-units (pixels, that is). This made the animation system much simpler, and actually working. So the figures are moving around the world perfectly now. So tomorrow is network coding time!
