A node that provides a [Shape3D] to a [CollisionObject3D] parent. A node that provides a [Shape3D] to a [CollisionObject3D] parent and allows to edit it. This can give a detection shape to an [Area3D] or turn a [PhysicsBody3D] into a solid object. [b]Warning:[/b] A non-uniformly scaled [CollisionShape3D] will likely not behave as expected. Make sure to keep its scale the same on all axes and adjust its [member shape] resource instead. $DOCS_URL/tutorials/physics/physics_introduction.html https://godotengine.org/asset-library/asset/126 https://godotengine.org/asset-library/asset/125 https://godotengine.org/asset-library/asset/678 Sets the collision shape's shape to the addition of all its convexed [MeshInstance3D] siblings geometry. [i]Obsoleted.[/i] Use [signal Resource.changed] instead. A disabled collision shape has no effect in the world. The actual shape owned by this collision shape.
