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.
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 a list of intersecting [PhysicsBody3D]s and [GridMap]s. The overlapping body's [member CollisionObject3D.collision_layer] must be part of this area's [member CollisionObject3D.collision_mask] in order to be detected.

Returns [code]true[/code] if intersecting any [Area3D]s, otherwise returns [code]false[/code]. The overlapping area's [member CollisionObject3D.collision_layer] must be part of this area's [member CollisionObject3D.collision_mask] in order to be detected.

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.
The area's gravity intensity (in meters per second squared). This value multiplies the gravity direction. This is useful to alter the force of gravity without altering its direction.
The [Node3D] which is used to specify the the direction and origin of an area-specific wind force. The direction is opposite to the z-axis of the [Node3D]'s local transform, and its origin is the origin of the [Node3D]'s local transform.
Emitted when a [Shape3D] of the received [param area] enters a shape of this area. Requires [member monitoring] to be set to [code]true[/code].
[param local_shape_index] and [param area_shape_index] contain indices of the interacting shapes from this area and the other area, respectively. [param area_rid] contains the [RID] of the other area. These values can be used with the [PhysicsServer3D].

var other_shape_node = area.shape_owner_get_owner(other_shape_owner)

Emitted when the received [param body] enters this area. [param body] can be a [PhysicsBody3D] or a [GridMap]. [GridMap]s are detected if their [MeshLibrary] has collision shapes configured. Requires [member monitoring] to be set to [code]true[/code].
Emitted when the received [param body] exits this area. [param body] can be a [PhysicsBody3D] or a [GridMap]. [GridMap]s are detected if their [MeshLibrary] has collision shapes configured. Requires [member monitoring] to be set to [code]true[/code].
