2D area for detection and physics and audio influence.
2D area that detects [CollisionObject2D] nodes overlapping, entering, or exiting. Can also alter or override local physics parameters (gravity, damping) and route audio to a custom audio bus. To give the area its shape, add a [CollisionShape2D] or a [CollisionPolygon2D] node as a [i]direct[/i] child (or add multiple such nodes as direct children) of the area. [b]Warning:[/b] See [ConcavePolygonShape2D] for a warning about possibly unexpected behavior when using that shape for an area.

Returns a list of intersecting [Area2D]s. The overlapping area's [member CollisionObject2D.collision_layer] must be part of this area's [member CollisionObject2D.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 [PhysicsBody2D]s. The overlapping body's [member CollisionObject2D.collision_layer] must be part of this area's [member CollisionObject2D.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.
If [code]true[/code], the given area overlaps the Area2D. [b]Note:[/b] The result of this test is not immediate after moving objects. For performance, the list of overlaps is updated once per frame and before the physics step. Consider using signals instead.
If [code]true[/code], the given physics body overlaps the Area2D. [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 [code]body[/code] argument can either be a [PhysicsBody2D] or a [TileMap] instance (while TileMaps are not physics bodies themselves, they register their tiles with collision shapes as a virtual physics body).
- The rate at which objects stop spinning in this area. Represents the angular velocity lost per second. See [member ProjectSettings.physics/2d/default_angular_damp] for more details about damping.
- The name of the area's audio bus.
- If [code]true[/code], the area's audio bus overrides the default audio bus.
- The area's gravity intensity (in pixels per second squared). This value multiplies the gravity vector. This is useful to alter the force of gravity without altering its direction.
- The falloff factor for point gravity. The greater the value, the faster gravity decreases with distance.
- If [code]true[/code], gravity is calculated from a point (set via [member gravity_vec]). See also [member space_override].
- The area's gravity vector (not normalized). If gravity is a point (see [member gravity_point]), this will be the point of attraction.
- The rate at which objects stop moving in this area. Represents the linear velocity lost per second. See [member ProjectSettings.physics/2d/default_linear_damp] for more details about damping.
- If [code]true[/code], other monitoring areas can detect this area.
- If [code]true[/code], the area detects bodies or areas entering and exiting it.
- The area's priority. Higher priority areas are processed first.
- Override mode for gravity and damping calculations within this area. See [enum SpaceOverride] for possible values.
