| A common misconception ((Or at least, a misconception held by me, the author of this page)) is that ''HingeJoint'' constrains the ''rotation'' or ''localRotation'' of the ''Transform'' that it is attached to. This is not strictly true. **''HingeJoint'' only constrains the relative rotation between its own ''RigidBody'' and the ''Rigidbody'' in the ''ConnectedBody'' field**. | A common misconception ((Or at least, a misconception held by me, the author of this page)) is that ''HingeJoint'' constrains the ''rotation'' or ''localRotation'' of the ''Transform'' that it is attached to.

| Another common misconception ((Again, by me, the author)) is that ''HingeJoint.angle'' and ''HingJoint.axis'' represent the ''rotation'' of the ''Transform'' that it is attached to. This is also not strictly true. That is, **''Quaternion.AngleAxis(hingeJoint.angle, hingeJoint.axis)'' does not necessarily equal ''hingeJoint.transform.rotation'' or ''hingeJoint.transform.localRotation''**. | Another common misconception ((Again, by me, this author)) is that ''HingeJoint.angle'' and ''HingJoint.axis'' represent the ''rotation'' of the ''Transform'' that it is attached to.

| These two misconceptions, taken together, can make a ''HingeJoint'' behave quite differently from what you might expect. | These two misconceptions, taken together, can make a ''HingeJoint'' behave quite differently from what you might expect. |
