**Inherits:** :ref:`CollisionObject3D<class_CollisionObject3D>` **<** :ref:`Node3D<class_Node3D>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

A region of 3D space that detects other :ref:`CollisionObject3D<class_CollisionObject3D>`\ s entering or exiting it.

.. rst-class:: classref-introduction-group

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

**Area3D** is a region of 3D space defined by one or multiple :ref:`CollisionShape3D<class_CollisionShape3D>` or :ref:`CollisionPolygon3D<class_CollisionPolygon3D>` child nodes. It detects when other :ref:`CollisionObject3D<class_CollisionObject3D>`\ s enter or exit it, and it also keeps track of which collision objects haven't exited it yet (i.e. which one are overlapping it).

This node can also locally alter or override physics parameters (gravity, damping) and route audio to custom audio buses.

\ **Warning:** Using a :ref:`ConcavePolygonShape3D<class_ConcavePolygonShape3D>` inside a :ref:`CollisionShape3D<class_CollisionShape3D>` child of this node (created e.g. by using the **Create Trimesh Collision Sibling** option in the **Mesh** menu that appears when selecting a :ref:`MeshInstance3D<class_MeshInstance3D>` node) may give unexpected results, since this collision shape is hollow. If this is not desired, it has to be split into multiple :ref:`ConvexPolygonShape3D<class_ConvexPolygonShape3D>`\ s or primitive shapes like :ref:`BoxShape3D<class_BoxShape3D>`, or in some cases it may be replaceable by a :ref:`CollisionPolygon3D<class_CollisionPolygon3D>`.

.. _class_Area3D_property_gravity_point_unit_distance:

.. rst-class:: classref-property

:ref:`float<class_float>` **gravity_point_unit_distance** = ``0.0``

- void **set_gravity_point_unit_distance** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_gravity_point_unit_distance** **(** **)**

The distance at which the gravity strength is equal to :ref:`gravity<class_Area3D_property_gravity>`. For example, on a planet 100 meters in radius with a surface gravity of 4.0 m/s², set the :ref:`gravity<class_Area3D_property_gravity>` to 4.0 and the unit distance to 100.0. The gravity will have falloff according to the inverse square law, so in the example, at 200 meters from the center the gravity will be 1.0 m/s² (twice the distance, 1/4th the gravity), at 50 meters it will be 16.0 m/s² (half the distance, 4x the gravity), and so on.

The above is true only when the unit distance is a positive number. When this is set to 0.0, the gravity will be constant regardless of distance.

Method Descriptions
-------------------

.. _class_Area3D_method_get_overlapping_areas:

.. rst-class:: classref-method

:ref:`Area3D[]<class_Area3D>` **get_overlapping_areas** **(** **)** |const|

Returns a list of intersecting **Area3D**\ s. The overlapping area's :ref:`CollisionObject3D.collision_layer<class_CollisionObject3D_property_collision_layer>` must be part of this area's :ref:`CollisionObject3D.collision_mask<class_CollisionObject3D_property_collision_mask>` in order to be detected.

For performance reasons (collisions are all processed at the same time) this list is modified once during the physics step, not immediately after objects are moved. Consider using signals instead.

.. _class_Area3D_method_get_overlapping_bodies:

.. rst-class:: classref-method

:ref:`Node3D[]<class_Node3D>` **get_overlapping_bodies** **(** **)** |const|

Returns a list of intersecting :ref:`PhysicsBody3D<class_PhysicsBody3D>`\ s and :ref:`GridMap<class_GridMap>`\ s. The overlapping body's :ref:`CollisionObject3D.collision_layer<class_CollisionObject3D_property_collision_layer>` must be part of this area's :ref:`CollisionObject3D.collision_mask<class_CollisionObject3D_property_collision_mask>` in order to be detected.

:ref:`bool<class_bool>` **has_overlapping_areas** **(** **)** |const|

Returns ``true`` if intersecting any **Area3D**\ s, otherwise returns ``false``. The overlapping area's :ref:`CollisionObject3D.collision_layer<class_CollisionObject3D_property_collision_layer>` must be part of this area's :ref:`CollisionObject3D.collision_mask<class_CollisionObject3D_property_collision_mask>` in order to be detected.

:ref:`bool<class_bool>` **has_overlapping_bodies** **(** **)** |const|

Returns ``true`` if intersecting any :ref:`PhysicsBody3D<class_PhysicsBody3D>`\ s or :ref:`GridMap<class_GridMap>`\ s, otherwise returns ``false``. The overlapping body's :ref:`CollisionObject3D.collision_layer<class_CollisionObject3D_property_collision_layer>` must be part of this area's :ref:`CollisionObject3D.collision_mask<class_CollisionObject3D_property_collision_mask>` in order to be detected.

----

.. _class_Area3D_method_overlaps_area:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **overlaps_area** **(** :ref:`Node<class_Node>` area **)** |const|

Returns ``true`` if the given **Area3D** intersects or overlaps this **Area3D**, ``false`` otherwise.

\ **Note:** The result of this test is not immediate after moving objects. For performance, list of overlaps is updated once per frame and before the physics step. Consider using signals instead.

----

.. _class_Area3D_method_overlaps_body:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **overlaps_body** **(** :ref:`Node<class_Node>` body **)** |const|

Returns ``true`` if the given physics body intersects or overlaps this **Area3D**, ``false`` otherwise.

\ **Note:** The result of this test is not immediate after moving objects. For performance, list of overlaps is updated once per frame and before the physics step. Consider using signals instead.

The ``body`` argument can either be a :ref:`PhysicsBody3D<class_PhysicsBody3D>` or a :ref:`GridMap<class_GridMap>` instance. While GridMaps are not physics body themselves, they register their tiles with collision shapes as a virtual physics body.
