游戏使用二维数组制作，加载了12张图片；准确地说是6对。当一个图块被点击时，它会被添加 1，从而使其成为 2，从而显示它。当显示 2 个图块并单击第三个图块时，前 2 个图块被隐藏。

我的问题：如何检查两个显示的图块是否显示相同的图像？如果它们显示相同的图像，我如何确保它们保持不变并且不会在单击第三个图块时被隐藏？

我尝试制作某种与数组对应的计数器，但根本不起作用。也没有检查一个数组是否等于另一个。

任何帮助，将不胜感激。非常非常感谢你。

这是我的参考代码：

    // Number of columns and rows in the grid
int cols;
int rows;
int counter = 0; //counts how many are shown
boolean[] tracker = new boolean[12];

PImage [][] img = new PImage[4][3]; // load images

int[][] grid;

void setup() {
  size(600, 600);
  cols = height/4; //I want 4
  rows = width/3; //I want 3
  for (int m =0; m<tracker.length;m++){
        tracker[m]=false; //To laod array as false. Will be used to track numbers given out to make sure each every image is only put out once (but in reality I have pairs)
  }
  for (int i =0; i<img.length; i++) {
    for (int j=0; j<img[i].length;j++) {
      //int k = (j * 4 + i)%6;//2D array to 1D
      int k = (int)random(0,12);
      while(tracker[k]) //While it's true, pick 0-11 corepsonding to an image
      {
        k = (int)random(0,12);
      }
      tracker[k]=true; //Make it true, therefore can't be picked again
      img[i][j] = loadImage("img" + k + ".jpeg"); //Load the images
    }
  }
  grid = new int[cols][rows]; //To make the 2D array of 30 and 30
  for (int i=0; i<cols; i++) {
    for (int j=0; j<rows; j++) {
      grid[i][j] = 1; //If mouse clicked, will by multiplied by -1 to change if black or white
    }
  }
}

void draw() {
  rects(); //Calls the function to display rectangles
}

void rects() {
  for (int i=0; i<cols; i++) {
    for (int j=0; j<rows; j++) {
      if (grid[i][j]== 1) { //if grid at i,j is 1, change white
        fill(255); //white
        rect(cols*i, rows*j, cols, rows);
      }
      if (grid[i][j]== 2) { //if grid at i,j is -1, change black
        image(img[i][j], cols*i, rows*j);
        //rect(cols*0, rows*0, cols, rows);
      }
    }
  }
}

void mouseClicked() {
  for (int i=0; i<cols; i++) {
    for (int j=0; j<rows; j++) {
      if (mouseX<(i*cols)+cols && mouseX >= i*cols && mouseY<((j)*rows+rows) && mouseY >= (j)*rows) { // find square that is clicked then change color
        counter++;
        if (counter == 3) {
          for (int k=0; k<cols; k++) {
            for (int l=0; l<rows; l++) {
              grid[k][l]=1; //Making it 1 again, thus white
            }
          }
          counter =1;
        }
        grid[i][j] +=1; //By adding one, we make it show the imahe
      }
    }
  }
}

您不想尝试比较 PImage，因为它很慢且并不总是准确的。

您不想存储比您需要的更多的图像，因为这会浪费内存。仅存储唯一图像。

您想将模型与视图分开。你永远不需要操纵你的图像。您只需要知道它们应该显示在哪里以及搜索匹配项的过程。您存储图像的方式应该与该逻辑分开。

我建议您创建一个包含 6 个独特图像的“PImage”数组。然后，创建一个“int”数组，其大小是唯一图像数量的两倍（因为您想要成对）。最后，创建一个与“int”数组长度相同的“布尔”数组。

因此，在设置时，您将使用 6 个图像填充图像数组（“PImage”数组），使用图像数组的键（0 到 5 重复，即 {0,1）填充标签数组（“int”数组） ,2,3,4,5,0,1,2,3,4,5)，打乱标签数组，并用“false”值填充显示数组（“布尔”数组）。

当用户单击一个磁贴时，您将确定磁贴编号（0 到 11），将该磁贴编号的显示设置为 true，并将该磁贴编号存储为第一次单击。当用户单击另一个磁贴时，首先检查它是否与第一次单击的磁贴编号不同，然后将显示设置为 true，并将磁贴编号存储为第二次单击。现在已经单击了两个，检查每个图块编号的标签数组，看看它们是否相等。如果是，则您有一个匹配项，如果没有，则没有匹配项，第一次和第二次单击将被重置，并且这些图块编号的显示再次设置为 false。

在下面我创建的示例中，有两个 pde 文件，match 和 colors。match.pde 文件包含了解标签匹配方法所需的所有内容。colors.pde 仅作为生成随机颜色的方法包含在内，您无需担心。重点是使用颜色向您展示逻辑，以便您可以使用图像来实现它。

顺便说一句，您不必使用 Java shuffle 方法，特别是如果您想避免使用 Java 库并只使用处理。一种流行的方法是 Fisher-Yates Shuffle。 http://en.wikipedia.org/wiki/Fisher%E2%80%93Yates_shuffle
