Manages the physics for a SKScene.

Remarks
Every SKScene has a PhysicsWorld property that holds a SKPhysicsWorld object that manages the physics for that scene.
The SKPhysicsWorld has several responsibilities:
- Providing global values such as Gravity.:
- Connecting SKPhysicsBodys with the AddJoint(SKPhysicsJoint) method.:
- Raising events when SKPhysicsBody begin or end contact with each other (see the ContactDelegate property and the DidBeginContact and DidEndContact methods).:
- Enumerating bodies that intersect geometry (EnumerateBodies(CGPoint, CGPoint, SKPhysicsWorldBodiesAlongRayStartEnumeratorHandler) and GetBody(CGPoint, CGPoint) methods).:
Constructors
| Name | Description |
|---|---|
| SKPhysicsWorld(NativeHandle) |
A constructor used when creating managed representations of unmanaged objects. Called by the runtime. |
| SKPhysicsWorld(NSCoder) |
A constructor that initializes the object from the data stored in the unarchiver object. |
| SKPhysicsWorld(NSObjectFlag) |
Constructor to call on derived classes to skip initialization and merely allocate the object. |
