練習筆記50 : 猜拳遊戲 App

這個作業是參考Apple官方的剪刀石頭布(RPS)範例 製作猜拳遊戲App

並練習使用enum~

這次做的猜拳遊戲是 左一拳,右一拳,大家一起收一拳～～

先在File裡建立enum~

//剪刀石頭布
enum Sign:String{
    case rock = "✊🏻"
    case paper = "🖐🏻"
    case scissor = "✌🏻"
}

//遊戲結果
enum GameState:String{
    case leftHand = "左一拳"
    case rightHand = "右一拳"
    case oneHand = "大家一起收一拳"
    case win = "你贏了"
    case lose = "你輸了"
    case draw = "平手"
}

建立畫面及宣告各個需要用到的東西～～

 //玩家剪刀石頭布判斷
    var sign : Sign!
    //玩家出左右拳判斷
    var count = 0
    //建立遊戲狀態的array
    let gameState = [GameState.leftHand,GameState.rightHand,GameState.oneHand]
    //講話功能
    let synthesizer = AVSpeechSynthesizer()

    
    //顯示電腦出拳emoji的Label
    @IBOutlet var computerSignLabel: [UILabel]!
    //顯示玩家出拳emoji的Label
    @IBOutlet var playerSignLabel: [UILabel] = []
    //顯示目前遊戲狀態的Label
    @IBOutlet weak var gameStateLabel: UILabel!
    //出拳Button
    @IBOutlet weak var rockButton: UIButton!
    @IBOutlet weak var scissorButton: UIButton!
    @IBOutlet weak var paperButton: UIButton!

開始做功能

    //電腦出拳
    func play(){
        let computerSign = randomSign()
        //用count判斷這次電腦出拳是左手還右手
        computerSignLabel[count-1].text = computerSign.rawValue
        
    }

    //唸出遊戲狀態
    func speak(){
        
        let speechUtterance = AVSpeechUtterance(string: gameStateLabel.text!)
         speechUtterance.voice = AVSpeechSynthesisVoice(language: "zh-TW")
         synthesizer.speak(speechUtterance)
      
    }
   //玩家出拳
    @IBAction func chooseSign(_ sender: UIButton) {
        //計算出拳次數 判斷遊戲階段
        count += 1
        if count < 3{
            //判斷玩家出什麼拳
            switch sender.tag{
            case 0: sign = .rock
            case 1: sign = .scissor
            case 2: sign = .paper
            default: break
            }
            //用count判斷這次玩家出拳是左手還右手
            playerSignLabel[count-1].text = sign.rawValue
            //判斷遊戲狀態要顯示的文字
            gameStateLabel.text = gameState[count].rawValue
            //唸出遊戲狀態
            speak()
            
            //玩家出拳後電腦也隨機出拳
            play()
            
            //設定button可否點選
            if count == 2{
                rockButton.isEnabled = false
                scissorButton.isEnabled = false
                paperButton.isEnabled = false
                playerSignLabel[0].backgroundColor = .tintColor
                playerSignLabel[1].backgroundColor = .tintColor
                
            }
        }
}

     //大家一起收一拳
    @IBAction func selectOneHand(_ sender: UIButton) {
        //畫面設定
        gameStateLabel.text = " "
        gameStateLabel.backgroundColor = .systemCyan
        playerSignLabel[0].backgroundColor = .systemGray5
        playerSignLabel[1].backgroundColor = .systemGray5
        //電腦隨機收拳及玩家收拳
        let randomNumber = Int.random(in: 0...1)
        playerSignLabel[sender.tag].text = " "
        computerSignLabel[randomNumber].text = " "
        
        //判斷輸贏
        let player = playerSignLabel[1 - sender.tag].text
        let computer = computerSignLabel[1-randomNumber].text
        
        if player != computer{
            switch player{
            case Sign.rock.rawValue:
                if computer == Sign.scissor.rawValue{
                    gameStateLabel.text = GameState.win.rawValue
                    
                }else{
                    gameStateLabel.text = GameState.lose.rawValue
                }
            case Sign.paper.rawValue:
                if computer == Sign.rock.rawValue{
                    gameStateLabel.text = GameState.win.rawValue
                }else{
                    gameStateLabel.text = GameState.lose.rawValue
                }
            case Sign.scissor.rawValue:
                if computer == Sign.paper.rawValue{
                    gameStateLabel.text = GameState.win.rawValue
                }else{
                    gameStateLabel.text = GameState.lose.rawValue
                }
            default:break
            }
            
        }
        else{
            gameStateLabel.text = GameState.draw.rawValue
        }
    }

      //reset
    func reset(){
        count = 0
        gameStateLabel.text = gameState[0].rawValue
        gameStateLabel.backgroundColor = .clear
        speak()
        playerSignLabel[0].text = " "
        playerSignLabel[1].text = " "
        computerSignLabel[0].text = " "
        computerSignLabel[1].text = " "
        rockButton.isEnabled = true
        scissorButton.isEnabled = true
        paperButton.isEnabled = true
        playerSignLabel[0].backgroundColor = .systemGray5
        playerSignLabel[1].backgroundColor = .systemGray5
        
    }

做好的樣子～

完成～～
