常数

public final int DIMENSIONS = 4;
public final int MOVE_RIGHT = 1;
public final int MOVE_LEFT = 2;
public final int MOVE_UP = 3;
public final int MOVE_DOWN = 4;

主要的

PuzzleFrame board;

void setup(){
  size(401,401);
  board = new PuzzleFrame();
  background(100);
}

void draw(){
  background(100);
  board.draw();
}

void keyPressed()
{
  if(key == CODED)
  {
    if(keyCode == RIGHT) board.moveTile(MOVE_RIGHT);
    if(keyCode == LEFT) board.moveTile(MOVE_LEFT);
    if(keyCode == UP) board.moveTile(MOVE_UP);
    if(keyCode == DOWN) board.moveTile(MOVE_DOWN);
  }
}

创建拼图框架的类

class PuzzleFrame{
  private Tile[][] puzzleFrame;
  private Tile[][] solvedPuzzleFrame;

  public PuzzleFrame()
  {
    puzzleFrame = new Tile[DIMENSIONS][DIMENSIONS];
    solvedPuzzleFrame = new Tile[DIMENSIONS][DIMENSIONS];
    int tileNumber = 1;
    for(int i = 0; i < DIMENSIONS; i++)
    {
      for(int j = 0; j < DIMENSIONS; j++)
      {
        puzzleFrame[i][j] = new Tile(tileNumber, j*100, i*100);
        solvedPuzzleFrame[i][j] = new Tile(tileNumber, j*100, i*100);
        tileNumber++;
      }
    }
  }

  public void draw()
  {
    for(int i = 0; i < DIMENSIONS; i++)
    {
      for(int j = 0; j < DIMENSIONS; j++)
      {
        puzzleFrame[i][j].draw();
      }
    }
  }

  public void moveTile(int side)
  {
    if(isMoveAllowed(side))
    {
      switch(side)
      {
        case MOVE_RIGHT:
        {
          for(int i = 0; i < DIMENSIONS; i++)
          {
            for(int j = 0; j < DIMENSIONS; j++)
            {
              if(puzzleFrame[i][j].getTileNumber() == DIMENSIONS*DIMENSIONS)
              {
                Tile tempTile = puzzleFrame[i][j];
                puzzleFrame[i][j] = puzzleFrame[i][j-1];
                puzzleFrame[i][j-1] = tempTile;
                System.out.println("right");
                break;
              }
            }
          }
          break;          
        }
      }
    }
  }

  private boolean isMoveAllowed(int side)
  {
    switch(side)
    {
      case MOVE_RIGHT:
      {
        for(int i = 0; i < DIMENSIONS; i++)
        {
          for(int j = 0; j < DIMENSIONS; j++)
          {
            if(puzzleFrame[i][j].getTileNumber() == DIMENSIONS*DIMENSIONS)
            {
              if(j > 0) return true;
            }
          }
        }
        break;
      }
    }
    return false;
  }

}

用于创建拼图框架的 tile 类

class Tile{

  private final int mTileNumber;
  private final int width = 100;
  private final int height = 100;
  private String number = "";
  private int xpos;
  private int ypos;
  private int xOffSet;
  private int yOffSet;

  public Tile(int tileNumber, int xpos, int ypos)
  {
    mTileNumber = tileNumber;
    number += tileNumber;
    textSize(64);
    this.xpos = xpos; this.ypos = ypos;
    xOffSet = 30;
    yOffSet = 70;
    if(mTileNumber >= 10)
    {
      xOffSet = 10;
    }
  }

  public void draw()
  {
    if(mTileNumber == DIMENSIONS*DIMENSIONS)
    {
    }
    else
    {
      strokeWeight(2);
      fill(255);
      rect(xpos, ypos, width, height);
      fill(0);
      text(number, xpos+xOffSet, ypos+yOffSet);
    }
  }

  public int getTileNumber()
  {
    return mTileNumber;
  }
}

我正在尝试制作 15 个益智游戏，但我遇到的问题是，当我按下箭头键 RIGHT 时，puzzleFrame 数组的内容会发生变化（我通过调试器在 Eclipse 中检查了它）但在处理绘制的图像时保持不变。现在我的代码只包含一个允许向右滑动图块的函数。老实说，我不明白为什么即使数组的内容发生了变化，图像仍然保持不变。

我知道这并不能回答您的问题，但是您如何在分配期间避免 Tile 类中的编译器错误： mTileNumber = tileNumber 您将 mTileNumber 声明为最终变量，因此您不应该将其重新分配给任何东西。
