在附加到相同游戏对象的 Joint2D 断开时调用。
当 Joint2D.reactionForce 高于关节的 Joint2D.breakForce 或 Joint2D.reactionTorque 高于关节的 Joint2D.breakTorque 时,关节会断开。
当关节断开时,会调用 OnJointBreak2D 并且会传入断开的特定 Joint2D。
调用 OnJointBreak2D 之后,关节会自动从游戏对象中移除并删除。
另请参阅:Joint2D.breakForce、Joint2D.breakTorque、Joint2D.reactionForce 和 Joint2D.reactionTorque。
