Swift - 在井字遊戲中添加Tie和playagain功能

Question

我想添加tie功能，然後再次播放按鈕會出現。 我是Swift中的新人。

我困在領帶功能，並保持它的工作正常。

import UIKit 

class ViewController: UIViewController { 
    @IBOutlet var winnerLable: UILabel! 
    @IBOutlet var playAgainButton: UIButton! 

    @IBAction func playAgain(_ sender: Any) { 
     activeGame = true 
     activePlayer = 1 
     gameState = [0, 0, 0, 0, 0, 0, 0, 0, 0] 

     var _: UIButton 

     for i in 1..<10 { 
      if let button = view.viewWithTag(i) as? UIButton { 
       button.setImage(nil, for: []) 
      } 

      winnerLable.isHidden = true 
      playAgainButton.isHidden = true 

      winnerLable.center = CGPoint(x: winnerLable.center.x - 500, y: winnerLable.center.y) 

      playAgainButton.center = CGPoint(x: playAgainButton.center.x - 500, y: playAgainButton.center.y) 
     } 
    } 

    // 1 is nought and 2 is cross 
    var turnCount = 0 
    var activeGame = true 
    var activePlayer = 1 

    var gameState = [0, 0, 0, 0, 0, 0, 0, 0, 0] //0 is empty 

    var winnerCombination = [[0, 1, 2], [3, 4, 5], [6, 7, 8], [0, 3, 6], [1, 4, 7], [2, 5, 8], [0, 4, 8], [2, 4, 6]] 

    @IBAction func buttonPressed(_ sender: AnyObject) { 
     let activePosition = sender.tag - 1 

     if gameState[activePosition] == 0 && activeGame { 
      gameState[activePosition] = activePlayer 

      if activePlayer == 1 { 
       sender.setImage(UIImage(named: "nought.png"), for: []) 
       activePlayer = 2 
      } else { 
       sender.setImage(UIImage(named: "cross.png"), for: []) 
       activePlayer = 1 
      } 

      for combination in winnerCombination { 
       if gameState[combination[0]] != 0 && gameState[combination[0]] == gameState[combination[1]] && gameState[combination[1]] == gameState[combination[2]] { 
        // we have a winner 
        activeGame = false 
        winnerLable.isHidden = false 
        playAgainButton.isHidden = false 

        if gameState[combination[0]] == 1{ 
         winnerLable.text = "Nought has won" 
        } else { 
         winnerLable.text = "crosses has won" 
        } 
       } 

       UIView.animate(withDuration: 1, animations: { 
        self.winnerLable.center = CGPoint(x: self.winnerLable.center.x + 500, y: self.winnerLable.center.y) 

        self.playAgainButton.center = CGPoint(x: self.playAgainButton.center.x + 500, y: self.playAgainButton.center.y) 
       }) 
      } 
     } 
    } 

    override func viewDidLoad() { 
     super.viewDidLoad() 

     winnerLable.isHidden = true 
     playAgainButton.isHidden = true 

     winnerLable.center = CGPoint(x: winnerLable.center.x - 500, y: winnerLable.center.y) 

     playAgainButton.center = CGPoint(x: playAgainButton.center.x - 500, y: playAgainButton.center.y) 
    } 
} 

Answer 1

您可以添加，在buttonPressed方法的末尾，領帶測試：

else if !gameState.contains(0) { 
    winnerLable.text = "it's a tie" 
    winnerLable.isHidden = false 
    playAgainButton.isHidden = false 
} 

Answer 2

歡迎來到SO。通常情況下，我會將這種「告訴我如何實現我的應用程序」的問題標記爲不合適，但是您是新的，所以無論如何我都會回答。

你在你的buttonPressed IBAction中有邏輯來檢測獲勝狀態。

想一想，什麼是領帶？當每個廣場都滿了而沒有贏家時，就會發生聯繫，對吧？因此，如果聲明中添加了「我們有贏家」的else子句，並遍歷整個數組，尋找零單元格。如果沒有贏家，並且沒有零單元格，那就是一條平行線。

看看你是否可以實現該邏輯。如果沒有，請編輯您的問題以顯示底部的新代碼，告訴我們它有什麼問題，我們會幫您解決這個問題。

Answer 3

這裏是獲取如果領帶代碼....只是把這個代碼在主控制器和你做......

activeGame =假

  for i in gameState { 


       if i == 0 { 

        activeGame = true 
        break 



       } 
      } 

      if activeGame == false { 

       winnerLable.text = "its a tie" 
       winnerLable.isHidden = false 
       playAgainButton.isHidden = false 


      } 

Answer 4

所以，這裏是我的完整的工作代碼...

進口的UIKit

類的ViewController：UIViewController的{

@IBOutlet var winnerLable: UILabel! 


@IBOutlet var playAgainButton: UIButton! 



@IBAction func playAgain(_ sender: Any) { 

    activeGame = true 

    activePlayer = 1 

    gameState = [0, 0, 0, 0, 0, 0, 0, 0, 0] 

    var _: UIButton 

    for i in 1..<10 { 

     if let button = view.viewWithTag(i) as? UIButton { 

     button.setImage(nil, for: []) 


     } 

     winnerLable.isHidden = true 

     playAgainButton.isHidden = true 

     winnerLable.center = CGPoint(x: winnerLable.center.x - 500, y: winnerLable.center.y) 

     playAgainButton.center = CGPoint(x: playAgainButton.center.x - 500, y: playAgainButton.center.y) 



    } 



} 
// 1 is nought and 2 is cross 

var activeGame = true 

var activePlayer = 1 

var gameState = [0, 0, 0, 0, 0, 0, 0, 0, 0] //0 is empty 

var winnerCombination = [[0, 1, 2], [3, 4, 5], [6, 7, 8], [0, 3, 6], [1, 4, 7], [2, 5, 8], [0, 4, 8], [2, 4, 6]] 


@IBAction func buttonPressed(_ sender: AnyObject) { 

    let activePosition = sender.tag - 1 

    if gameState[activePosition] == 0 && activeGame { 

     gameState[activePosition] = activePlayer 


     if activePlayer == 1 { 

      sender.setImage(UIImage(named: "nought.png"), for: []) 
      activePlayer = 2 

     } else { 

      sender.setImage(UIImage(named: "cross.png"), for: []) 
      activePlayer = 1 
      } 

     for combination in winnerCombination { 


      if gameState[combination[0]] != 0 && gameState[combination[0]] == gameState[combination[1]] && gameState[combination[1]] == gameState[combination[2]] {

       activeGame = false 


       winnerLable.isHidden = false 
       playAgainButton.isHidden = false 

       if gameState[combination[0]] == 1{

      activeGame = false 

      for i in gameState { 


       if i == 0 { 

        activeGame = true 
        break 



       } 
      } 

      if activeGame == false { 

       winnerLable.text = "its a tie" 
       winnerLable.isHidden = false 
       playAgainButton.isHidden = false 


      } 

       UIView.animate(withDuration: 1, animations: { 

       self.winnerLable.center = CGPoint(x: self.winnerLable.center.x + 500, y: self.winnerLable.center.y) 

       self.playAgainButton.center = CGPoint(x: self.playAgainButton.center.x + 500, y: self.playAgainButton.center.y) 

       }) 

      } 

     } 

    } 
    override func viewDidLoad() { 

    super.viewDidLoad() 
    // Do any additional setup after loading the view, typically from a nib. 



    winnerLable.isHidden = true 

    playAgainButton.isHidden = true 

    winnerLable.center = CGPoint(x: winnerLable.center.x - 500, y: winnerLable.center.y) 

    playAgainButton.center = CGPoint(x: playAgainButton.center.x - 500, y: playAgainButton.center.y)
