十五益智游戏

Question

我正在做一个十五的益智游戏，我希望你只能点击空框旁边的一个数字，但现在你可以点击任何地方...如何改变这个？我认为您可以为列和行创建一个 if- 语句..

   for(i=0 ; i++<100 ; x = Math.floor(Math.random()*16), y = Math.floor(Math.random()*16), currentBoard[x] = currentBoard.splice(y, 1, currentBoard[x])[0]);


      repaint(); // Redraw puzzle board

Answer 1

根据我对您代码的理解，您有 16 个按钮，每行 4 行。每次单击按钮时，该按钮的数组值和空白按钮交换。您快到了。这里最重要的细节是按钮 ID，它始终保持不变。

需要添加点击按钮ID和空白按钮ID的比较，需要条件

我不会为您提供代码，因为我不想直接给出答案。我要给你逻辑：

在您的最后一个函数中，在 if( currentBoard[i]==0 ) zeroIndex = i 之后；

**Else if** the id(clicked button) == id(blank button)-1. OR id(blank button)+1. OR
id(blank button)-4. OR id(blank button)+4 ........

Swap the elements.

Else

don't swap the elements.

祝你好运！希望这有帮助。

Answer 2

for (i = 0; i < 16; i++) {
  if (currentBoard[i] == 0) {
    if ((i - current) == 4 || (current - i) == 4 || (current - i) == 1 || (i - current) == 1) {
      zeroIndex = i;
      swapArrElems(current, zeroIndex);
      repaint();
    }
  }
}
