Meanwhile, back on my main project, I'm having much trouble with just trying to get a simple "chase player" behaviour. Pathfinding (with A*) wasn't too hard but there's lots of icky low-level details for moving a character around the environment which are creaping into my behaviour and generally cluttering it up. And due to the highly temporary nature of behaviours stopping and restarting a behaviour (such as repathing when the player moves far enough to invalidate the current behaviour) tends to lead to unpleasant animation jittering as it rapidly switches between idle and running animations.
So I'm trying to pull out some of the low-level movement and animation into a "locomotion" layer.
