Adjusting Actual Stride Length automatically changes the value for Parametric
Stride Length.
Actual Stride Height Sets the rise or fall between footsteps. You can use this
parameter to create a set of footsteps going up or down a slope or a stairway.
The value for Actual Stride Height is the difference in height in units between
each of the new footsteps. Positive values step up and negative values step
down.
Stride Height=5 units
Time to Next Footstep Specifies the number of frames in each foot movement
cycle. A cycle starts with the frame that a foot touches the ground, continues
as the foot lifts and moves, and ends with the frame before the foot touches
the ground again. This parameter is only enabled if Auto Timing is on.
Speed Displays the number of units the biped will move per frame. It changes
in response to changes in the other parameters but cannot be adjusted directly.
The following two parameters are only enabled when Auto Timing is off.
You can use these parameters instead of Auto Timing to control the speed of
the forward motion over the series of footsteps. However, because these
parameters both affect the footsteps’ time in contact with the ground, using
them to slow down a walk gives the walk a hesitant, ‘stop-go’ quality.
Walk Footstep Specifies the number of frames each footstep will be on the
ground during a walk.
The higher the number, the longer each biped foot remains in contact with
the ground and, consequently, the slower the speed of the walking motion.
