系統開發-05介面調整

先來修改莊家部分，發完牌後，莊家第一章牌應該是蓋起來的，所以我們來調整一下UpdateUI()即可

protected void UpdateUI()
{
    
    //......以上省略....

    dealer = (Player)Session["Dealer"];

    //顯示莊家手牌
    for (int i = 0; i < dealer.cards.Count; i++)
    {
    		 //**新增**
        if (i == 0)	//顯示的第一張牌改為蓋幾來的圖片
        {
            lab_dealer.Text += $"<img src='./images/BACK.png'>";
        }
        else
        {
            lab_dealer.Text += $"<img src='./images/{dealer.cards[i].Rank}-{dealer.cards[i].Suit}.png'>";
        }
    }
}

執行結果：

但以上有個問題，就是牌局結束後，莊家的蓋牌並不會顯示，所以再來修改一下

新增遊戲狀態(status)，分為遊戲中(status=0)和遊戲結束(status=1)兩個狀態，除了遊戲初始化設定(status=0)以外將所有的會結束牌局的地方(玩家爆牌與停牌)加入遊戲結束(status=1)

protected void ResetGame() {        //初始化遊戲參數與動作(初始發牌)
    //將資料存到Session
    Session["Deck"] = new Deck();
    Session["Dealer"] = new Player();
    Session["Player"] = new Player();

    //**新增**
    status = 0;
    Session["Status"] = status;

    //初始發牌
    DrawForPlayer();
    DrawForDealer();
    DrawForPlayer();
    DrawForDealer();

    //清空label內容
    lab_deck.Text = "";
    lab_dealer.Text = "";
    lab_player.Text = "";
    lab_msg.Text = "";

    btn_hit.Enabled = true;
    btn_stand.Enabled = true;
    btn_newgame.Enabled = false;
}

protected void UpdateUI()
{
    deck = (Deck)Session["Deck"];
    lab_deck.Text = deck.ShowCards();

    //Label顯示前先清空內容
    lab_player.Text = "";
    lab_dealer.Text = "";

    player = (Player)Session["Player"];

    //顯示玩家手牌
    for (int i = 0; i < player.cards.Count; i++)
    {
        lab_player.Text += $"<img src='./images/{player.cards[i].Rank}-{player.cards[i].Suit}.png'>";
    }

    dealer = (Player)Session["Dealer"];
    //**新增 **
    status = (int)Session["Status"];			//取得status

    //顯示莊家手牌
    for (int i = 0; i < dealer.cards.Count; i++)
    {
        //**新增**
        if (i == 0 && status == 0)		//加入status判斷，遊戲結束(status=1)不顯示蓋牌
        {
            lab_dealer.Text += $"<img src='./images/BACK.png'>";
        }
        else
        {
            lab_dealer.Text += $"<img src='./images/{dealer.cards[i].Rank}-{dealer.cards[i].Suit}.png'>";
        }
    }
}

protected void btn_hit_Click(object sender, EventArgs e)
{
    DrawForPlayer();

    if (player.IsBusted())
    {
        lab_msg.Text = $"{player.CalculatePoints()}點，你爆掉了! 莊家贏!";

        //**新增**
        status = 1;
        Session["Status"] = status;

        //牌局結束，不能再按發牌和停牌
        btn_hit.Enabled = false;
        btn_stand.Enabled = false;
        btn_newgame.Enabled = true;
    }

    UpdateUI();
}

protected void btn_stand_Click(object sender, EventArgs e)
{
    player = (Player)Session["Player"];
    dealer = (Player)Session["Dealer"];

    //小於18點持續要牌
    while (dealer.CalculatePoints() < 18)
    {
        DrawForDealer();
    }

    //如果莊家沒有爆牌，比較莊家和玩家的點數
    int playerScore = player.CalculatePoints();
    int dealerScore = dealer.CalculatePoints();

    if (dealer.IsBusted() || playerScore > dealerScore)
    {
        //玩家贏
        if (dealer.IsBusted())
        {
            lab_msg.Text = $"莊家 {dealer.CalculatePoints()}點，玩家 {player.CalculatePoints()}點! 莊家爆掉了! 玩家贏!";
        }
        else
        {
            lab_msg.Text = $"莊家 {dealer.CalculatePoints()}點，玩家 {player.CalculatePoints()}點! 玩家贏!";
        }
    }
    else if (playerScore < dealerScore)
    {
        //莊家贏
        lab_msg.Text = $"莊家 {dealer.CalculatePoints()}點，玩家 {player.CalculatePoints()}點! 莊家贏!";
    }
    else
    {
        //平手
        lab_msg.Text = $"莊家 {dealer.CalculatePoints()}點，玩家 {player.CalculatePoints()}點! 雙方平手!";
    }

    //**新增**
    status = 1;
    Session["Status"] = status;

    btn_hit.Enabled = false;
    btn_stand.Enabled = false;
    btn_newgame.Enabled = true;

    UpdateUI();
}

執行結果：

以上已調整好遊戲的介面，算是一個完整的遊戲了。

後續再新增一下遊戲的回和數，與玩家輸贏次數。
