Member Variables
|
|
----------------
|
|
|
|
.. _class_Area_angular_damp:
|
|
|
|
- :ref:`float<class_float>` **angular_damp** - The rate at which objects stop spinning in this area. Represents the angular velocity lost per second. Values range from ``0`` (no damping) to ``1`` (full damping).
|
|
|
|
.. _class_Area_audio_bus_name:
|
|
|
|
- :ref:`String<class_string>` **audio_bus_name** - The name of the area's audio bus.
|
|
|
|
.. _class_Area_audio_bus_override:

|
|
|
|
.. _class_Area_collision_layer:
|
|
|
|
- :ref:`int<class_int>` **collision_layer** - The area's physics layer(s). Collidable objects can exist in any of 32 different layers. A contact is detected if object A is in any of the layers that object B scans, or object B is in any layers that object A scans. See also ``collision_mask``.

|
|
.. _class_Area_gravity_distance_scale:

|
|
|
.. _class_Area_gravity_vec:
|
|
|
|
- :ref:`Vector3<class_vector3>` **gravity_vec** - The area's gravity vector (not normalized). If gravity is a point (see :ref:`is_gravity_a_point<class_Area_is_gravity_a_point>`), this will be the point of attraction.

|
|
|
|
- :ref:`float<class_float>` **linear_damp** - The rate at which objects stop moving in this area. Represents the linear velocity lost per second. Values range from ``0`` (no damping) to ``1`` (full damping).
|
|
|
|
.. _class_Area_monitorable:
|

|
|
|

|
- :ref:`String<class_string>` **reverb_bus_name**
|
|
|
|
.. _class_Area_reverb_bus_uniformity:
|
|
|
|
- :ref:`float<class_float>` **reverb_bus_uniformity**
|
|
|
|
.. _class_Area_space_override:
|
|
|
|
- :ref:`int<class_int>` **space_override** - Override mode for gravity and damping calculations within this area. See the SPACE_OVERRIDE\_\* constants for values.
|
|
|
|
|
|
Numeric Constants
|
|
-----------------
|
|
|
|
- **SPACE_OVERRIDE_DISABLED** = **0** --- This area does not affect gravity/damping.
|
|
- **SPACE_OVERRIDE_COMBINE** = **1** --- This area adds its gravity/damping values to whatever has been calculated so far (in ``priority`` order).
|
|
- **SPACE_OVERRIDE_COMBINE_REPLACE** = **2** --- This area adds its gravity/damping values to whatever has been calculated so far (in ``priority`` order), ignoring any lower priority areas.
|
|
- **SPACE_OVERRIDE_REPLACE** = **3** --- This area replaces any gravity/damping, even the defaults, ignoring any lower priority areas.
|
|
- **SPACE_OVERRIDE_REPLACE_COMBINE** = **4** --- This area replaces any gravity/damping calculated so far (in ``priority`` order), but keeps calculating the rest of the areas.
