<brief_description>
|
|
3D area for detection and physics and audio influence.
|
|
</brief_description>
|
|
<description>
|
|
3D area that detects [CollisionObject3D] nodes overlapping, entering, or exiting. Can also alter or override local physics parameters (gravity, damping) and route audio to custom audio buses.
|
|
To give the area its shape, add a [CollisionShape3D] or a [CollisionPolygon3D] node as a [i]direct[/i] child (or add multiple such nodes as direct children) of the area.
|
|
[b]Warning:[/b] See [ConcavePolygonShape3D] (also called "trimesh") for a warning about possibly unexpected behavior when using that shape for an area.

<method name="get_overlapping_areas" qualifiers="const">
|

<return type="Area3D[]" />
|
|
<description>
|
|
Returns a list of intersecting [Area3D]s. The overlapping area's [member CollisionObject3D.collision_layer] must be part of this area's [member CollisionObject3D.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.

Returns [code]true[/code] if the given [Area3D] intersects or overlaps this [Area3D], [code]false[/code] otherwise.
|
|
[b]Note:[/b] 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 [param body] argument can either be a [PhysicsBody3D] or a [GridMap] instance. While GridMaps are not physics body themselves, they register their tiles with collision shapes as a virtual physics body.
