Variables 变量

angle		The angle of the line in space. 在空间中，线路的角
jointSpeed		The current joint speed. 当前关节的速度。
jointTranslation		The current joint translation. 当前关节转化。
limits		Restrictions on how far the joint can slide in each direction along the line. 限制住关节距离，使这个关节能沿着线路的每个方向滑动多远
limitState		Gets the state of the joint limit. 获取关节极限的状态。
motor		Parameters for a motor force that is applied automatically to the Rigibody2D along the line. 参数用于一个电机力，这个力自动地沿着路线作用于二维刚体
referenceAngle		The angle referenced between the two bodies used as the constraint for the joint. 在两个物体之间的夹角，用于约束关节
useLimits		Should motion limits be used? 运动限定应使用吗？
useMotor		Should a motor force be applied automatically to the Rigidbody2D? 电机力应自动地作用于二维刚体吗？
