**Inherits:** :ref:`Joint<class_joint>` **<** :ref:`Spatial<class_spatial>` **<** :ref:`Node<class_node>` **<** :ref:`Object<class_object>`

**Category:** Core

Brief Description
-----------------

A hinge between two 3D bodies.

Member Variables
----------------

  .. _class_HingeJoint_angular_limit/bias:

- :ref:`float<class_float>` **angular_limit/bias** - The speed with which the rotation across the axis perpendicular to the hinge gets corrected.

  .. _class_HingeJoint_angular_limit/enable:

- :ref:`bool<class_bool>` **angular_limit/enable** - If ``true`` the hinges maximum and minimum rotation, defined by :ref:`angular_limit/lower<class_HingeJoint_angular_limit/lower>` and :ref:`angular_limit/upper<class_HingeJoint_angular_limit/upper>` has effects.

  .. _class_HingeJoint_angular_limit/lower:

- :ref:`float<class_float>` **angular_limit/lower** - The minimum rotation. only active if :ref:`angular_limit/enable<class_HingeJoint_angular_limit/enable>` is ``true``.

  .. _class_HingeJoint_angular_limit/relaxation:

- :ref:`float<class_float>` **angular_limit/relaxation** - The lower this value, the more the rotation gets slowed down.

  .. _class_HingeJoint_angular_limit/softness:

- :ref:`float<class_float>` **angular_limit/softness**

  .. _class_HingeJoint_angular_limit/upper:

- :ref:`float<class_float>` **angular_limit/upper** - The maximum rotation. only active if :ref:`angular_limit/enable<class_HingeJoint_angular_limit/enable>` is ``true``.

  .. _class_HingeJoint_motor/enable:

- :ref:`bool<class_bool>` **motor/enable** - When activated, a motor turns the hinge.

  .. _class_HingeJoint_motor/max_impulse:

- :ref:`float<class_float>` **motor/max_impulse** - Maximum acceleration for the motor.

  .. _class_HingeJoint_motor/target_velocity:

- :ref:`float<class_float>` **motor/target_velocity** - Target speed for the motor.

  .. _class_HingeJoint_params/bias:

- :ref:`float<class_float>` **params/bias** - The speed with which the two bodies get pulled together when they move in different directions.


Enums
-----

  .. _enum_HingeJoint_Flag:

enum **Flag**

- **FLAG_USE_LIMIT** = **0** --- If ``true`` the hinges maximum and minimum rotation, defined by :ref:`angular_limit/lower<class_HingeJoint_angular_limit/lower>` and :ref:`angular_limit/upper<class_HingeJoint_angular_limit/upper>` has effects.
- **FLAG_ENABLE_MOTOR** = **1** --- When activated, a motor turns the hinge.
- **FLAG_MAX** = **2** --- End flag of FLAG\_\* constants, used internally.

  .. _enum_HingeJoint_Param:

enum **Param**

- **PARAM_BIAS** = **0** --- The speed with which the two bodies get pulled together when they move in different directions.
- **PARAM_LIMIT_UPPER** = **1** --- The maximum rotation. only active if :ref:`angular_limit/enable<class_HingeJoint_angular_limit/enable>` is ``true``.
- **PARAM_LIMIT_LOWER** = **2** --- The minimum rotation. only active if :ref:`angular_limit/enable<class_HingeJoint_angular_limit/enable>` is ``true``.
- **PARAM_LIMIT_BIAS** = **3** --- The speed with which the rotation across the axis perpendicular to the hinge gets corrected.
- **PARAM_LIMIT_SOFTNESS** = **4**
- **PARAM_LIMIT_RELAXATION** = **5** --- The lower this value, the more the rotation gets slowed down.
- **PARAM_MOTOR_TARGET_VELOCITY** = **6** --- Target speed for the motor.
- **PARAM_MOTOR_MAX_IMPULSE** = **7** --- Maximum acceleration for the motor.
- **PARAM_MAX** = **8** --- End flag of PARAM\_\* constants, used internally.


Description
-----------

Normally uses the z-axis of body A as the hinge axis, another axis can be specified when adding it manually though.
