Merrie,
That would be setup on the horse (vehicle),
You'll have to setup a attach point as well, and either use motion blending, or a seperate set of animations for the rider.
I am also working on getting a horse & rider working, so- if I beat you to finishing this, I'll post my code in here for you
(and others) to use.. With luck someone will beat me to it though ;-) as my ability to write code, well- sucks.
However I really don't see it too much different than setting up a vehicle (planning on effectively copying the vehicle in
the adventure game, but utilizing my horse animations for it's movements, and then build in the motion blending for
attacks afterwards.
