记忆游戏随机颜色

Question

嘿，大家我正在创建一个使用4x4 2D阵列的记忆游戏。

我有4x4用0-7的一对整数填充，它们是随机分散的。我想为每个对分配一个颜色，所以当鼠标点击该方块时，分配的颜色将基于该整数出现，您将不得不根据其相应的匹配颜色找到另一个整数。 我一直在遇到这个setColor方法的一些问题。我将包括我的整个代码，以防其他地方混乱，这就是为什么。目前，如果我点击每个广场，一旦我使用了我分配了两次的所有8种颜色，但其中一些颜色与另一个区块上的相同整数所在的位置不匹配。同样，当我多次点击同一个瓷砖时，它会在2-3种颜色之间变化，我不确定我做错了什么。

我需要建议的部分是我已经分配的setColor方法和我的逻辑。

Answer 1

这个代码

colorIndex = board[row][column]; 
    board[row][column] = board[x1][y1]; 
    board[x1][y1] = colorIndex; 

不断从改变颜色，改变

colorIndex = board[x1][y1]; 

色彩匹配问题是因为您选择建设板两次：第一次在paint方法的第一次运行中，您可以在其中打印阵列，然后在init方法，其中板被覆盖，让你看到不同的价值观

解决这个问题，你应该在init方法搭板只有一次，并呼吁print2DArray事后检查，所以

buildBoard(4); 
print2DArray(board); //<-- add this line to verify colors 

，你可以省略firstRun标志和所有关联的代码。

评论或删除此代码：

/*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 
    {*/
