function GetRelativePointVelocity (relativePoint : Vector3) : Vector3
Description描述
The velocity relative to the rigidbody at the point relativePoint.
相对于刚体在relativePoint点的速度。
GetRelativePointVelocity will take the angularVelocity of the rigidbody into account when calculating the velocity.
GetRelativePointVelocity在计算速度的时候将考虑刚体的角速度angularVelocity。
