SCNNode is a part of the SceneKit Framework. An SCNNode object represents a portion of a scene graph. A node by itself has no visible content when the scene containing it is rendered—it represents only a position in space (and transformation of coordinate spaces) relative to its parent node. To construct a scene, you use a hierarchy of nodes to create its structure, then add lights, cameras, and geometry to nodes to create visible content.

How can I move an SCNNode in SceneKit, but affected by gravity?

SCNAction.move(to:SCNVector3) doesn't work. It moves the shape but the shape doesn't fall. There's some other action?
