Question

我正在开发Connect Four项目，但我正在努力获胜。我认为这与我如何循环网格有关。它水平工作但不垂直工作，它有点对角工作。

        declare @FullName varchar;
        declare @InvoiceID int;
        declare @CustomerID int;
        declare @DeliveryInstructions varchar;
        declare Salescur cursor for
        --select---
            select p.FullName, InvoiceID,CustomerID,DeliveryInstructions
            from Sales.Invoices s 
            inner join Application.People p
            on s.SalespersonPersonID = p.PersonID
            where InvoiceDate = '2016-05-31'
            and s.SalespersonPersonID = 8;

        open Salescur;
        fetch next from Salescur into @FullName,@InvoiceID,@CustomerID,
        @DeliveryInstructions;
        while @@FETCH_STATUS = 0
        begin 
            --print @InvoiceID + CHAR(13);
            print @FullName + 'has delivery instructions to these addresses: ' + @DeliveryInstructions
            fetch next from Salescur into @FullName,@InvoiceID,@CustomerID,
        @DeliveryInstructions;
        end
        close Salescur;
        deallocate Salescur;
    end;

我认为这只会检查非空的最后一行。

Java并不关心缩进，因此如果没有大括号，if和for只会使用它后面的语句。这意味着您的if (checkColumn...只运行一次，而不是每列运行一次。

您可能想尝试类似

的内容

public boolean gameStatus(MyBoard gameBoard, int columnPosition, CellState gameToken) { 
    int rowPosition = 0;
    for (int i = 0; i < gameBoard.getWidth(); i++) {
        for (int j = 0; j < gameBoard.getHeight(); j++) {
            if (gameBoard.get(i, columnPosition) != CellState.FREE) {
                rowPosition = i;
            }
        }
        if (checkColumn(gameBoard, columnPosition, gameToken, rowPosition)) {
            return true;
        }
    }

总的来说。我建议不要在没有大括号的情况下撰写if，for和while语句。它保存的两个字符不值得你不小心引入的错误

通过连接四个网格循环
