java - 在处理(java)编码中使用数组或类的数字网格

Question

使用处理我正在尝试重新创建蛇和梯子游戏。网格完成了，“骰子”也完成了。

我想像实际的蛇梯子游戏一样对网格进行编号。并且还添加一种方式，当我移动棋子时，“骰子”(显示在屏幕底部的数字)和棋子将移动的盒子数量之间会有一个链接。

我尝试尽可能少地更改您的代码。至于运动和骰子，那是一个不同的主题，你没有代码可以做到这一点...我建议先尝试一些事情，如果你不能得到它问另一个问题!

对于贪吃蛇游戏中的数字，您需要先填充行，从下面开始，每行交换检查矩形的x:

// Class that displays a single cell of a checker board
class GameBoard {
  /*-----------------------properties------------------*/
  float x;
  float y;
  int rVal;
  int gVal;
  int bVal;
  color squareColor; //color of cell fill
  int ccSize; //size of cell
  int index;


  /*-----------------------methods---------------------*/
  // constructor method
  public GameBoard(int tempX, int tempY, color tempColor, int tempSize, int i) {
    x = tempX;
    y = tempY;
    squareColor = tempColor; 
    ccSize = tempSize;
    index = i;
  }

  // draws    ccColor = tempColor; the cell. This is public because other objects will need to 
  // be able to tell the object to draw itself.
  public void display() {
    fill(squareColor);
    noStroke();
    rectMode(CORNER);
    rect(x, y, ccSize, ccSize);
    fill(255);
    text(String.valueOf(index), x-ccSize*0.5, y-ccSize*0.5, 200, 200);
  }
}

class Dice {  
  float xDice;
  float yDice;
  float diceSize;
  String randomNumber = "";

  public Dice (float xNewDice, float yNewDice, float newDiceSize) {
    xDice = xNewDice;
    yDice = yNewDice;
    diceSize = newDiceSize;
    randomNumber = "4";
  }
  public void displayDice() {
    stroke(0);

    if (referenceNumber == 1) {
