试图阻止随机生成的图片框不相互交叉

Question

我正在开发一个 windows 形式的程序，可以生成随机坐标点来画鱼。我需要鱼停止相互交叉，但我编写的代码不起作用。生成的坐标应放入矩形中，然后对照所有其他点矩形进行检查。鱼不断相交。知道为什么吗？ Code I wrote to stop the intersection.

for (int i = 0; i < fishNumber; i++)
{
    // Checks for overlapping
    fishX = x.Next(200, 3100);
    fishY = y.Next(100, 1620);

    fishPoints.Add(new Point(fishX, fishY));
    for (int j = 0; j < i; j++)
    {
        while (i != 0 && new Rectangle(fishPoints[i], new Size(200, 134)).IntersectsWith(new Rectangle(fishPoints[j], new Size(200, 134))))
        {
            fishPoints.RemoveAt(i);
            fishX = x.Next(200, 3100);
            fishY = y.Next(100, 1620);
            fishPoints.Add(new Point(fishX, fishY));
        }
    }
}

Answer 1

尝试更像下面的东西。它只会在确定它不与任何其他鱼相交后添加点：

Size fishSize = new Size(200, 134);
for (int i = 0; i < fishNumber;i++)
{
    Point pt;
    bool collided;
    do
    {
        collided = false;
        pt = new Point(x.Next(200, 3100), y.Next(100, 1620));
        Rectangle rcNewFish = new Rectangle(pt, fishSize);
        foreach(Point otherPt in fishPoints)
        {
            if (rcNewFish.IntersectsWith(new Rectangle(otherPt, fishSize)))
            {
                collided = true;
                break;
            }
        }
    } while (collided);
    fishPoints.Add(pt);
}
