随机生成麻烦,还是脚本麻烦?

理想情况下,它必须在棋盘区域的随机位置上给我5个黑色方块。但实际上它给我的不到黑色方块。

我真的坚持这个,因为我真的找不到答案。

您的小应用程序的问题在于fieldcheck功能。您遇到的问题是,正如The_asMan所说,检查中发生的错误是它正在运行。问题是,当你在做一些边界检查时:

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

当您对iRow和iColumn值执行某些操作以查看相邻方块中是否包含项目时,这不包括在内。我将fieldcheck操作更改为以下内容,似乎可以解决这个问题:

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,请考虑更改以下行:

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

致:

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

这可以为数字提供更好的结果,因为数组是0索引的,而你生成的数字是5-20而不是4-19。 (我假设0-3的缓冲点是有意的)。
