A value assigned and read by GameplayKit to rate the desirability of a move in your game.
- iOS 9.0+
- macOS 10.11+
- tvOS 9.0+
Your game does not assign to or read from this property directly. Instead, when you adopt the
GKGame protocol, you simply provide a read/write implementation of this property. When you use the
GKMinmax class to select optimal moves during gameplay, GameplayKit assigns values to this property in order to rate the desirability of each move to a given player.
