c# - 单击时随机化的数字网格

Question

我正在制作一款游戏，该游戏涉及在网格中查找并单击一个数字（0-9），每次单击正确的数字时都会随机化。

我想得到它，以便当您单击正确的数字时，网格会再次随机化。你会怎么做？

这就是它最终的样子：

Answer 1

I assume you're rendering an array of integers in order:

for (int i = 0; i < arrayOfNumbers.Length; i++ ) {
    // rendering here
    render(arrayOfNumbers[i]);
}

If thats the case.. just randomize the array after a successful click.. somewhat like this:

var rnd = new System.Random();
var arrayOfNumbers = Enumerable.Range(1, 9).OrderBy(r => rnd.Next()).ToArray();

Then you can just re-render (or let your game loop continue to render the array). Since the array has changed, your rendering will too.

Answer 2

每次您检测到点击正确的数字时（我希望您知道如何执行此操作），您只需随机化您在网格中显示的数字数组：

//Fisher-Yates algorithm
Random generator = new System.Random();
int len = array.Length;
while (len > 1)
{
    len--;
    int k = generator.Next(len + 1);
    int temp = array[k];
    array[k] = array[len];
    array[len] = temp;
}
