■ Is each footstep a left or right footstep?
Planning for Footstep Timing
■ What is the support relationship between left and right footsteps? In other
words, does the timing of the footsteps resemble a walk, run or jump
pattern? A character doing a foxtrot or waltz, for example, is actually
moving with “walk” timing – the character shifts weight from one foot to
the other.
■ How long, in frames, should each footstep be? How long are the biped's
airborne periods?
■ Are there any periods of time where the biped is standing on two feet for
a while?
Choosing a Gait
A gait is a method or pattern of moving on foot.
When you create new footsteps, the timing is determined by
the gait you have chosen (Walk, Run, or Jump) and the parameters for that
gait. You must choose the gait before parameters can be set.
Choose the gait that most closely approximates the type of movement you
want to create. You can alter or adjust the gait after footsteps have been created.
Walk Gait
In a walk, at least one foot is always in contact with the ground. A period
where one or both feet are in contact with the ground is called a support period.
If both feet are on the ground, this is known as a double support period.
Turn on Walk before creating footsteps to create this type of gait.
The gait parameters of a walk are:
Walk Footstep The number of frames that each footstep remains on the
ground.
Double Support The number of frames in a double support period, that is,
when both feet are on the ground.
