C# 行方向

Question

我正在研究 GUI。我有一个使用 TableLayoutPanel 显示的游戏板。它有 6 列和 7 行。正方形数字的顺序正确，并且在某些行上它们应该从右到左。 例如;

---

• 23-22-21-20-19-18
• 12-13-14-15-16-17
• 11-10-9-8-7-6
• Start-1-2-3-4-5

但在我的代码中方形数字总是从左到右。你能帮忙吗？

    private void SetupGameBoard() {
    int counter = 0;

    for (int row = NUM_OF_ROWS-1; row > -1; row--) {
        for (int column = 0; column < NUM_OF_COLUMNS; column++) {
            SquareControl squareControl = new SquareControl
                (hareAndTortoiseGame.Board.Squares[counter], hareAndTortoiseGame.Players);
            if ((row == 6 && column == 0) || (row == 0 && column == 5)){
                squareControl.BackColor = Color.BurlyWood;
            }
            GameTableLayout.Controls.Add(squareControl, column, row);
            counter++;
        }
    }
}

Answer 1

您仅在一个方向上迭代，即从左到右。您的第一个 for 循环需要在向上和向下迭代列之间交替。

您想要一个沿行呈之字形排列的游戏板。向下迭代行的逻辑很好，从最高行开始然后向下移动。现在您只需要处理列即可。您声明列中的值在立即出现时始终从左到右。也就是说，我假设它们看起来像：

• 23-22-21-20-19-18
• 17-16-15-14-13-12
• 11-10-9-8-7-6-5
• 4-3-2- 1-start

这是因为你的列值总是从 0->max，但你还没有覆盖 max->0。

一些伪代码：

for number of rows
  if row % 2 == 0 //if we are on an even row
    iterate up
  else
    iterate down

一些未经测试的实际代码：

private void SetupGameBoard() {
        int counter = 0;

        for (int row = NUM_OF_ROWS-1; row > -1; row--) {
            if(row % 2 == 0){
               for (int column = NUM_OF_COLUMNS; column > -1; column--) {
                SquareControl squareControl = new SquareControl
                    (hareAndTortoiseGame.Board.Squares[counter], hareAndTortoiseGame.Players);
                if ((row == 6 && column == 0) || (row == 0 && column == 5)){
                    squareControl.BackColor = Color.BurlyWood;
                }
                GameTableLayout.Controls.Add(squareControl, column, row);
                counter++;
               }
            }
            else{
               for (int column = 0; column < NUM_OF_COLUMNS; column++) {
                SquareControl squareControl = new SquareControl
                    (hareAndTortoiseGame.Board.Squares[counter], hareAndTortoiseGame.Players);
                if ((row == 6 && column == 0) || (row == 0 && column == 5)){
                    squareControl.BackColor = Color.BurlyWood;
                }
                GameTableLayout.Controls.Add(squareControl, column, row);
                counter++;
               }
            }
        }

您显然可以将其中一些代码分解为其他方法，因为有很多重复的东西。这个想法是，根据您位于奇数行还是偶数行来完成之字形。

Answer 2

你只需要做一些数学计算。这是循环所有单元格（按单元格编号）并获取行和列的数学运算。剩下的就交给你了。注意：我没有测试...可能是拼写错误或语法错误。

const int maxCols = 6;
const int maxRows = 4;

int numberCells = maxCols * maxRows;  // zero based in main array.

for (int cellNumber = 0; cellNumber < numberCells; cellNumber)
{
     int row;
     int col;

     row = maxRows - floor(cellNumber / maxRows);

     bool oddRow = (row % 2) == 1;

     col = oddRow ? (cellNumber % maxCols) + 1 : maxCols - (cellNumber % maxCols);

     // I believe the following is what you want to do in your proc.
     SquareControl squareControl = new SquareControl(hareAndTortoiseGame.Board.Squares[cellNumber], hareAndTortoiseGame.Players);
     if ((row == 6 && col == 0) || (row == 0 && col == 5))
     // if ((cellNumber == 0) || (cellNumber == (numberCells-1)))
     {
        squareControl.BackColor = Color.BurlyWood;
     }
     GameTableLayout.Controls.Add(squareControl, col, row);

}
