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

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.

\ **Note:** Areas and bodies created with :ref:`PhysicsServer3D<class_PhysicsServer3D>` might not interact as expected with **Area3D**\ s, and might not emit signals or track objects correctly.

\ **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>`.

- |void| **set_gravity_point_unit_distance**\ (\ value\: :ref:`float<class_float>`\ )
- :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.
