系統開發-06優化遊戲狀態

2024/11/13閱讀時間約 33 分鐘

上一篇新增遊戲狀態的控制，這一篇預計加入遊戲回合數與玩家輸贏次數，但若是用上一篇的作法，會多存好幾個Session，控制上也比較分散，所以來優化一下作法，就是新增一個類別專門來儲存這些控制變數

新增一個Game類別

//**新增**
public class Game
{
    public int totalRound { get; set; }     //遊戲回合
    public int playerWin { get; set; }      //玩家贏的局數
    public int dealerWin { get; set; }      //玩家輸的局數
    public int tie { get; set; }            //平局的局數
    public int status { get; set; }         //遊戲狀態

    public Game()
    {
        totalRound = 1;
        playerWin = 0;
        dealerWin = 0;
        tie = 0;

        status = 0; //0-遊戲中，1-結束
    }
}

再調整原本的status的程式碼，並在牌局結束的地方統計回合與輸贏次數

最後加做一個可隱藏牌堆的Checkbox，以下是完整的程式碼
