Re: [Virtools] character jumping, footref, and 'keep character on floor' woes

This is off course the way it's done in most games however  with virtools
the road is wide open for a more natural control scheme.
you could and can have a system where the movement of your character is
controlled through a dummy or frame, using a nice acceleration sytem, then
have 2 animations one running and one wlaking, both in sync. with in sync i
mean they should have their keyframes at the same spots. this in order to
create a blended animation at runtime. the speed or acceleration value from
the movement script could then be used to control the percentage of the
blended animation..  you could then even have the frame rate of the
animation be dependend on this accel/speed value..

thus no more warping between running/walking, or even walking backwards..
and it even works,, see http://www.littlechicken.nl/demo/senne/ although
rayB pointed out its not perfect yet, but the principles are there..

so there's a good alternative to animating movement  in max,, i can at least
recommend it.
