随机生成麻烦，还是脚本麻烦？

理想情况下，它必须在棋盘格的随机位置上给我 5 个黑色方块。但事实上它给了我更少的黑色方块。

我真的很坚持这个，因为我真的找不到答案。

原文

In ideal it must give me 5 black squares on random positions on checker field. But in fact it giving me less up to none black squares.

I really stuck into this because i literally can't find answer.

PS here is compiled app.

您的小应用程序的问题在于 fieldcheck 功能。正如 The_asMan 所说，您遇到的问题是在检查其运行时发生错误。问题是，当您进行一些边界检查时：

if ((iRow > 0)&&(iRow < HEIGHT))
if ((iColumn > 0) && (iColumn < WIDTH))

这并不包括您对 iRow 和 iColumn 值进行一些操作以查看相邻方块中是否有项目的情况。我将 fieldcheck 操作更改为以下内容，它似乎可以解决问题：

private function fieldcheck(iRow:int, iColumn:int):Boolean
{
    // I used looping here as it made the range checks simpler, plus you can
    // extend the range of a boxes space out pretty easily by changing the
    // - 1 and + 1 to a different number
    for(var r:int = iRow - 1; r == iRow + 1; r++) {
        if(r >= 0 && r < HEIGHT) {
            for(var c:int = iColumn - 1; c == iColumn + 1; c++) {
                if(c >= 0 && c < WIDTH) {
                    if(grid[r][c]==1) {
                        return false;
                    }
                }
            }
        }
    }
    return true;
}

此外，请考虑将以下行更改为：

clmn= (Math.random() * (WIDTH-5)) + 5;
rw = (Math.random() * (HEIGHT-5)) + 5;

To ：

clmn= (Math.random() * (WIDTH-5)) + 4;
rw = (Math.random() * (HEIGHT-5)) + 4;

这应该为您提供更好的数字结果，因为数组是 0 索引的，并且您生成的数字是从 5-20 而不是 4-19。 （我假设 0-3 的缓冲点是故意的）。

The problem with your little app lies in the fieldcheck function. The problem you are having is, as The_asMan says, an error occurring in the check that it is running. The problem is that while you are doing some bounds checking:

if ((iRow > 0)&&(iRow < HEIGHT))
if ((iColumn > 0) && (iColumn < WIDTH))

This doesn't cover when you are doing some operations on the iRow and iColumn values to see if neighboring squares have items in them. I changed the fieldcheck operation to the following and it seems to do the trick:

private function fieldcheck(iRow:int, iColumn:int):Boolean
{
    // I used looping here as it made the range checks simpler, plus you can
    // extend the range of a boxes space out pretty easily by changing the
    // - 1 and + 1 to a different number
    for(var r:int = iRow - 1; r == iRow + 1; r++) {
        if(r >= 0 && r < HEIGHT) {
            for(var c:int = iColumn - 1; c == iColumn + 1; c++) {
                if(c >= 0 && c < WIDTH) {
                    if(grid[r][c]==1) {
                        return false;
                    }
                }
            }
        }
    }
    return true;
}

Additionally, consider changing the following lines from:

clmn= (Math.random() * (WIDTH-5)) + 5;
rw = (Math.random() * (HEIGHT-5)) + 5;

To :

clmn= (Math.random() * (WIDTH-5)) + 4;
rw = (Math.random() * (HEIGHT-5)) + 4;

This should give you better results with the numbers as the arrays are 0-indexed and the numbers you were generating went from 5-20 instead of 4-19. (I'm assuming that the buffer spots of 0-3 are intentional).

这不是一个答案，而是一条评论，该评论太大而无法作为评论发布。
它工作正常，刷新几次后我看到 5 个黑色方块，我收到以下错误代码。
当这段代码弹出时，我没有得到任何方块。

This isn't an answer but a comment that is to big to post as a comment.
It was working fine and I saw 5 black squares after a few refreshes I got the following error code.
When this code popped up I got no squares.
