我想在制作迷宮游戲的同時實作回放功能

紅方：播放器圖片框；

藍色方塊：終點；

我在 PictureBox 中組織了一個迷宮。

如果玩家到達到達點，

我想實作一個重放功能，顯示他們再次找到的路徑，我該怎么辦？

  public void CreateNewMaze()
    {
        mazeTiles = new PictureBox[XTILES, YTILES];
        for (int i = 0; i < XTILES; i  )
        {
            for (int j = 0; j < YTILES; j  )
            {
                mazeTiles[i, j] = new PictureBox();
                int xPosition = (i * TILESIZE)   25;
                int yPosition = (j * TILESIZE)   10;
                mazeTiles[i, j].SetBounds(xPosition, yPosition, TILESIZE, TILESIZE);

                this.Controls.Add(mazeTiles[i, j]);
            }
        }
    }


 protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
    {
        int directionX = 0;
        int directionY = 0;
        switch (keyData)
        {
            case Keys.Left: directionX = -1;
                EndGame();
                break;

            case Keys.Right: directionX = 1;
                EndGame();
                break;

            case Keys.Up: directionY = -1;
                EndGame();
                break;

            case Keys.Down: directionY = 1;
                EndGame();
                break;

            default: return base.ProcessCmdKey(ref msg, keyData);
        }

        int x = directionX   (PlayerPictureBox.Left - 25) / TILESIZE;
        int y = directionY   (PlayerPictureBox.Top - 10) / TILESIZE;

        bool isRoad = mazeTiles[x, y].BackColor != Color.Black;
        if (isRoad)
        {
            PlayerPictureBox.Left  = directionX * TILESIZE;
            PlayerPictureBox.Top  = directionY * TILESIZE;
        }
        return true;
  
    }

uj5u.com熱心網友回復：

• 將每個步驟（或移動）添加到步驟串列中。
• 添加 Replay 方法，該方法從該串列中獲取每個步驟，執行它，然后等待一段時間。
• 在每場比賽之前清除“步驟”串列（例如在 CreateNewMaze 中）。
• 例如，按空格鍵開始播放。

因此，將此代碼添加到您的表單中：

    class Step
    {
        public int dx;
        public int dy;
    }

    List<Step> steps = new List<Step>();

    async void Replay(int delay = 50)
    {
        int firstX = 1; // Initial player position, maybe you'll have to change it
        int firstY = 1; 

        PlayerPictureBox.Left = 25   firstX * TILESIZE;
        PlayerPictureBox.Top = 10   firstY * TILESIZE;

        var copy = steps.ToArray(); // Let's make a copy of steps array, to avoid possible conflicts with working array.
        foreach (var step in copy)
        {
            PlayerPictureBox.Left  = step.dx * TILESIZE;
            PlayerPictureBox.Top  = step.dy * TILESIZE;

            await Task.Delay(delay);
        }
    }

像這樣修改 CreateNewMaze：

    public void CreateNewMaze()
    {
        // Add the following line
        steps.Clear();

        maze = new bool[XTILES, YTILES];
        //...

像這樣修改 ProcessCmdKey：

    protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
    {
        int directionX = 0;
        int directionY = 0;
        switch (keyData)
        {
            // Add the following:
            case Keys.Space:
                Replay();
                return true;
            // ...

和下面這樣：

        // ...
        if (isRoad)
        {
            // Add the following line
            steps.Add(new Step { dx = dx, dy = dy });

            PlayerPictureBox.Left  = directionX * TILESIZE;
            PlayerPictureBox.Top  = directionY * TILESIZE;
        }

我建議使用不同的 PictureBox 實體來回放這些步驟，以便用戶可以在回放運行時繼續播放。但我會把它留給你。
