IJointUtilsResetJoint Method

void ResetJoint(
	ConfigurableJoint joint
)

Parameters

joint

Type: UnityEngineConfigurableJoint
Joint to reset.

It's not the same as creating a default joint. The state is consistent but different from the default:

• All linear and angular drive modes set to Locked.
• All drives, springs and limits are zeroed.
• The coordinate system is reset to local. Y looks up, and X looks right.
• The connected body is not touched. Connection, if any, won't be broken on the reset.
• Any state accumulated so far (e.g. relative rotation or position) will be lost, and the joint will remember the new relative rotation/position of the connected objects.

Use this method before setting up a new or existing joint. By resetting the joint, you ensure it's in a consistent state, and the further adjustments will always give the same result regardless to how the joint was created and what components were affecting it.
