| [OnJointThreshold2D](/engine/6000.6/script-reference/unity/u2d/physics/physicscallbacks/ijointthresholdcallback/onjointthreshold2d.md) | Called when a [PhysicsEvents.JointThresholdEvent](/engine/6000.6/script-reference/unity/u2d/physics/physicsevents/jointthresholdevent.md) for the object occurs. This will always be called on the main-thread after the simulation has finished. |
