我一直在修改记忆匹配游戏中的代码以使用场景、声音和 2d 表格。添加场景是困难的部分。我将其设置为从我的 2d 表中随机选择项目。将它们加载到临时表中，将它们随机播放 shuffle()，然后 boardSet(); 加载他们的声音并将它们放在屏幕上。基本上游戏结束后，我希望场景重新加载或返回菜单重新开始。一遍又一遍地选择随机数据元素。{}
我已尝试返回菜单或转到重复的场景，但是我似乎无法正确卸载我的二维数组创建的对象，因为我无法正确地将每个项目添加到显示组中。我已经尝试了我能想到的一切。现在我的游戏循环设置为再次添加游戏，我想在找到一场比赛后重新开始游戏。
这个链接是我相信有关处理表格和组的信息的正确方向的开始。我仍然不知道如何循环遍历我的 2d 表以将所有内容包含在一个组中，然后正确卸载它。
