记忆游戏的Java

Question

可能重复：
memory game graphics java

我编码一个程序，它是一个4x4的记忆游戏。在这16个盒子里将会有一对从0到7的整数。我已经将所有这些都进行了随机化并正确编码。现在我试图弄清楚如何在每次鼠标点击盒子时将颜色与相应的整数进行配对。

这里的大部分代码。我知道这个游戏的逻辑尚未开始，但我现在更关注displayHit方法和setColor方法。只是发布整个代码，因为也许我在其他地方搞砸了。

/*Sets the background of your memory board to black*/ 
public void init() 
{ 
    setSize(400,400); 
    setBackground(Color.BLACK); 
    buildBoard(4); 

} 
/*This is main in java applets 
    You may need to add (not change) a couple things in this method 
*/ 
public void paint(Graphics canvas) 
{ 
    if(firstRun) //for the first run we need to build our random board 
    { 

     print2DArray(board); 
     buildBoard(4); 
     firstRun = false; 
    } 
    else // once our board is built we will display the game 
    { 
     displayGame(canvas); 
     if (mouseClicked) // if the mouse has been clicked 
     { 
      displayHit(canvas);//find which box the user clicked 
      mouseClicked = false; 
     } 
    } 
} 

/*

    sets x and y Mouse to the location of the mouse arrow

public boolean mouseDown(Event e, int x, int y) 
{ 
    mouseClicked = true; 
    xMouse = x; 
    yMouse = y; 
    repaint(); 
    return true; 
} 

/*DO NOT change this method 
    redraws the scene 
*/ 

public void update (Graphics g) 
{ 
    paint(g); 
}

Answer 1

它看起来像一次buildBoard是所谓的气温从未改变。这就是为什么你总是看到相同的颜色。

Answer 2

这个代码是罚款

public void setColor(Graphics g) 

{

switch(temp) 
{ 
case 0: g.setColor(Color.RED); 
break; 
case 1: g.setColor(Color.GREEN); 
break; 
case 2: g.setColor(Color.BLUE); 
break; 
case 3: g.setColor(Color.ORANGE); 
break; 
case 4: g.setColor(Color.CYAN); 
break; 
case 5: g.setColor(Color.MAGENTA); 
break; 
case 6: g.setColor(Color.PINK); 
break; 
case 7: g.setColor(Color.YELLOW); 
break; 
} 

} 

，但你是不是在代码中选择这种情况下/颜色，你要使用的任何地方设定温度。你需要改变温度，当你点击一个正方形，通过硬编码或随机产生0-7之间的数字来随机设置颜色
