2D area for detection and physics and audio influence.
|
|
</brief_description>
|
|
<description>
|
|
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.

Returns a list of intersecting [Area2D]s. 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.
