The initial world space orientation of the wheels relative to the
chassis/icon is unimportant when using this option, as reactor reorients
the bodies so that their local spaces continue to match during the
simulation.
2 On the Toy Car Properties rollout, set Toy Car Orientation to Common
Local Orientation.
3 Use the radio buttons to change the Suspension and Spin directions
relative to the bodies' local spaces. By default, the Spin axes are aligned
with the wheel and chassis's local X axes, and the suspension axes with
their Z axes.
To spin the Toy Car wheels:
1 On the Toy Car Properties rollout, turn on the Spin Wheels check box.
2 Change the default Ang (Angular) Speed and Gain values as necessary.
Angular Speed is the target angular velocity that reactor attempts to
achieve for the wheels. The Gain is the maximum angular impulse that
can be applied to the wheels in order to achieve the target velocity.
