WheelCollider クラスによって取得できる、ホイールの問い合わせ先になるクラスです。
Friction for the WheelCollider is computed separately from the rest of the physics, using
a slip based tire friction model. This allows for more realistic behaviour, but makes
wheel colliders ignore standard PhysicMaterial settings.
The way to simulate different ground materials is to query WheelCollider for its collision
information (see WheelCollider.GetGroundHit). Usually, you get the other collider the wheel
is hitting, and modify the wheel's WheelCollider.forwardFriction and WheelCollider.sidewaysFriction
based on the physic material of the ground.
The other members of the WheelHit structure are usually queried for information purposes or special
effects. For example, a "slipping tire" sound can be played if forwardSlip or sidewaysSlip
exceed some threshold.
