Self-balancing using
RotationalLimitMotors
Many games today use a blend of animations and physics to create realistic movement. For
animated characters, this revolves around balance. It could take the shape of a runner who
leans inwards through a curve to counter the centrifugal force. Creating a system like this is
not easy and requires a lot of tweaking. In this recipe, we'll look into some of the funda-
mentals of this, and we'll create a new
Control
class that will try to balance itself using
the rotational motors of
SixDofJoint
.
Note
Six Degrees of Freedom
(
SixDof
) relates to the six ways the joint can rotate: +x, -x, +y, -y,
+z, and -z. One way it differs from a
point2point
joint is that in addition, it also has
motors for each axis, which makes it possible for it to also apply force.
