General purpose area detection and influence for 3D physics.
General purpose area node for detection and 3D physics influence.
</brief_description>
<description>
General purpose area detection for 3D physics. Areas can be used for detection of objects that enter/exit them, as well as overriding space parameters (changing gravity, damping, etc). For this, use any space override different from AREA_SPACE_OVERRIDE_DISABLE and point gravity at the center of mass.
3D area that detects [CollisionObject] nodes overlapping, entering, or exiting. Can also alter or override local physics parameters (gravity, damping).
