Variables 变量

jointAngle		The current joint angle with respect to the reference angle. 当前关节的角相对于参考的角
jointSpeed		The current joint speed. 当前关节的速度。
limits		Limit of angular rotation on the joint. 在关节上角旋转的限制。
limitState		Gets the state of the joint limit. 获取的关节限制的状态。
motor		Parameters for the motor force applied to the joint. 电机动力的参数应用于关节。
referenceAngle		The angle referenced between the two bodies used as the constraint for the joint. 角所参考的在两个物体之间，被用作约束关节
useLimits		Should limits be placed on the range of rotation? 限定范围应被放置在旋转范围内？
useMotor		Should the joint be rotated automatically by a motor torque? 关节应被自动地旋转，并通过一个电机转矩？
