Overview

Package spritekit provides a fluent Go API over the macOS SpriteKit framework.

Construction

New… functions create objects; each With… method sets one property and returns its receiver, so configuration calls chain. A <Type>FromID constructor adopts an Objective-C object obtained elsewhere.

Lifecycle

A wrapper releases its Objective-C object automatically once the garbage collector finds it unreachable. Call Release to relinquish the reference deterministically (for objects holding scarce resources); Release is idempotent, and afterwards the wrapper's methods are no-ops returning zero values.

Main-thread requirements

Methods, setters, and constructors of classes Apple isolates to the main thread run there automatically; callers never need to arrange main-thread dispatch for the generated API.

Delegates

A …Delegate interface is implemented by a plain Go value and installed with the matching With… setter; the package builds the Objective-C delegate object behind the scenes. Optional protocol methods are separate one-method …Handler interfaces — implement the ones you need on the same value and the framework calls them too.

Types

Each base type below lists the concrete types you construct and pass where the base is accepted:
