dynamic()
Creates a physics body that can be affected by forces and collisions.
Declaration
class func dynamic() -> SelfReturn Value
A new physics body object.
Discussion
Use dynamic bodies for the elements of your scene that are moved by the physics simulation.
For the body to participate in collision detection or respond to forces, you must attach it to the physicsBody property of an SCNNode object in a scene.
SceneKit automatically creates a physics shape for the body when you attach it to a node, based on that node’s geometry property. To create a physics shape that’s based on the geometries of a node and its hierarchy of children, or to control the level of detail in a physics shape, create the physics shape manually using an SCNPhysicsShape class method.
