Visual C＃Hangman按鈕單擊事件

Question

我試圖在Visual C＃中創建一個Hangman游戲，但是遇到字母按鈕單擊事件時遇到了麻煩。

它的工作方式如下：玩家單擊字母按鈕（AZ）。 如果該按鈕的文本在他應該猜的單詞（guessWord）中，則會顯示字母，並增加正確的Guess計數器。 如果這封信中沒有猜測字詞，那么他離開的機會就會減少，並且會抽出一名子手。 當正確的猜詞> =猜詞的長度時，玩家將贏得游戲，而當他沒有更多機會時，他將輸掉游戲（他從8開始）。

我不知道當前代碼有什么問題。 有時，當我運行它時，只需單擊一個字母按鈕，我就會得到“您迷路了”的框。 有時，當猜出正確的字母時，程序會顯示字母，然后顯示“您丟失了”框。

void LetterBtn_Click(object sender, EventArgs e)
{

    //Event hook-up
    Button b = (Button)sender;
    char letterClicked = b.Text.ToCharArray()[0];

    //Disable button after it's been clicked
    b.Enabled = false;

    string gameOverTitle1 = "Congrats!";
    string gameOverTitle2 = "Sorry!";
    string gameOverMsg1 = "You won!";
    string gameOverMsg2 = "You lost!";

    char[] guessWordChars = guessWord.ToCharArray();

    //If the character is in the word
    if ((guessWord = guessWord.ToUpper()).Contains(letterClicked))
    {

        for (int i = 0; i < guessWord.Length; i++)
        {

            if (guessWordChars[i] == letterClicked)
            {

                //Reveal the character
                lblguessWord[i].Font = new Font("Bauhaus 93", 28, FontStyle.Regular);
                lblguessWord[i].Text = letterClicked.ToString();
                lblguessWord[i].ForeColor = Color.Fuchsia;
                //Increment counter
                correctGuess += 1;

            }

        }

        //Winning condition
        if (correctGuess >= guessWordChars.Length)
        {
            return;

        }

        //Tell the player he won the game
        frmGameOverBox frmGameOverBoxInstance = new frmGameOverBox(gameOverTitle2, gameOverMsg2);
        frmGameOverBoxInstance.ShowDialog();
    }

    else
    {

        //Incorrect guess
        if (chances > 0)
        {

            chances -= 1;
        }

        //Player lost the game
        else
        {

            //Reveal the word
            for (int k = 0; k < guessWordChars.Length; k++)
            {

                lblguessWord[k].Text = guessWordChars[k].ToString();

            }

            //Tell the player he lost the game
            frmGameOverBox frmGameOverBoxInstance = new frmGameOverBox(gameOverTitle1, gameOverMsg1);
            frmGameOverBoxInstance.ShowDialog();
        }
    }
}

Answer 1

您的問題在這里：

//Tell the player he won the game
frmGameOverBox frmGameOverBoxInstance = new frmGameOverBox(gameOverTitle2, gameOverMsg2);
frmGameOverBoxInstance.ShowDialog();

您正在混淆自己的標簽。 gameOverMsg2包含您的You Lost! 串。 改為：

//Tell the player he won the game
frmGameOverBox frmGameOverBoxInstance = new frmGameOverBox(gameOverTitle1, gameOverMsg1);
frmGameOverBoxInstance.ShowDialog();

您在else子句中有相同的問題：

//Tell the player he lost the game
frmGameOverBox frmGameOverBoxInstance = new frmGameOverBox(gameOverTitle1, gameOverMsg1);
frmGameOverBoxInstance.ShowDialog();

更改為此：

//Tell the player he lost the game
frmGameOverBox frmGameOverBoxInstance = new frmGameOverBox(gameOverTitle2, gameOverMsg2);
frmGameOverBoxInstance.ShowDialog();

您應該給變量名更多描述性的標題，以避免出現這種情況，例如gameOverLostMsg代替gameOverMsg2或者gameOverWinMsg代替gameOverMsg1 。

Answer 2

您在這里遇到問題：

    //Winning condition
    if (correctGuess >= guessWordChars.Length)
    {
        return;

    }

    //Tell the player he won the game
    frmGameOverBox frmGameOverBoxInstance = new frmGameOverBox(gameOverTitle2, gameOverMsg2);
    frmGameOverBoxInstance.ShowDialog();

此代碼返回用戶是否猜中所有的字母，並為用戶提供獲勝的消息，如果他/她猜對，但還沒有取得勝利。 您可能想要執行以下操作：

        //Winning condition
        if (correctGuess >= guessWordChars.Length)
        {
            //Tell the player he won the game
            frmGameOverBox frmGameOverBoxInstance = new frmGameOverBox(gameOverTitle2, gameOverMsg2);
            frmGameOverBoxInstance.ShowDialog();
        }

除此之外，在開頭添加一些調試代碼，以確保正確初始化變量，如下所示：

    Debug.WriteLine("correctGuess: " + correctGuess.ToString());
    Debug.WriteLine("chances: " + chances.ToString());
