AcessibilityFaceCursor

Requisitos

• iOS 13.0 +
• Funciona apenas para dispositivos com o conjunto de camera TrueDepth, Iphones da geração X e superior. (Por enquanto)

Instalação

AcessibilityFaceCursor esta disponível em CocoaPods. Para que possa intalar basta colocar a seguinte linha de comando no seu Podfile

pod 'AcessibilityFaceCursor'

Configurações iniciais para AccessibilityFaceAnchorViewController

O AccessibilityFaceAnchorViewController é uma classe herdade de UIViewcontroller,ou seja, através do polimofismo pode substituir a classe atual UIViewcontroller por ela para que possa usar os seus recursos. Esse pod utiliza três recursos do smartphone que devem ser autorizados pelo usuário. São eles:

• Privacy - Camera Usage Description
• Privacy - Microphone Usage Description
• Privacy - Speech Recognition Usage Description

O primeiro e para capturar o movimendo da cabeça do usuário, o segundo e terceiro e para quando a opção de ação for um comando de voz. Sem essas três solicitações o projeto dá error.

AccessibilityFaceAnchorViewController

Após modificar a herança da sua viewcontroller pela AccessibilityFaceAnchorViewController, e a captura da face do usuario já vai ser iniciada e ira aparecer um cursor na tela que se move de acordo com a face do usuario.

final class MenuScene: SKScene, MKMenuScene {
    var matchmaker: Matchmaker?
    
    func didAuthenticationChanged(to state: Matchmaker.AuthenticationState) {
        
    }
    
    func willStartGame() {
        //Presenting Scene example:
        view?.presentScene(GameScene(), transition: .crossFade(withDuration: 1.0))
    }
}

class GameScene: SKScene, MKGameScene {
    var multiplayerService: MultiplayerService 
    func didReceive(message: Message, from player: GKPlayer) {
        //Your Implementation
    }
    
    func didPlayerConnected() {
        //Your Implementation
    }
}

! MenuScene must be final class

In willStartGame() method present the scene:

func willStartGame() {
    view?.presentScene(GameScene(), transition: .crossFade(withDuration: 1.0))
}

To present matchmaker, call the function presentMatchmaker in MenuScene, or associate to a button action. Example:

startButton.actionBlock = presentMatchMaker

After Game Scene conforms to MKGameScene, you must associate the scene:

override func didMove(to view: SKView) {
    multiplayerService.gameScene = self
    //...
}

You can access all player in the match through multiplayerService.players. Example allocating all players in the scene:

func setupPlayers() {
    //...
    multiplayerService.players.forEach {
        let player = SpaceShip(gkPlayer: $0, texture: SKTexture(imageNamed: "ship"))
        allPlayersNode[$0] = player
        addChild(player)
    }
}

In GameViewController instantiate the Matchmaker and Menu Scene

if let skView = view as? SKView {
  let matchmaker = Matchmaker(authenticationViewController: self)
  let menuScene = MenuScene(matchmaker: matchmaker)
  skView.presentScene(menuScene)
}

Create custom messages

Create a struct that conforms to Message protocol. Example:

struct Position: Message {
    var point: CGPoint, angle: CGFloat
}

Send Messages

In your GameScene call the method send(_ message: Message) of MultiplayerService. Example:

let position = Position(point: position, angle: angle)
multiplayerService.send(position)

Receive Messages

The method didReceive(message: Message, from player: GKPlayer) in GameScene is responsable to receive all messages. Example, with Position, Attack and StartGame messages:

  func didReceive(message: Message, from player: GKPlayer) {
        guard let playerNode = allPlayersNode[player] else { return }
        switch message {
        case let position as Position:
            playerNode.changePlayer(position: position.point, angle: position.angle)
        case let startGame as StartGame:
            //Start game Logic
        case let attack as Attack:
            //Player attack Logic
        default:
            break
        }
    }
