之前我曾问过类似的问题，但我需要一些帮助来清理它。我的图像像拼字游戏瓷砖，我可以拖放到我的容器中，但我复制了很多代码。我还想知道如何能够将瓷砖放在任意数量的容器中而不是一个特定的容器中。这是代码的片段。有人可以请求帮助，因为我想避免重复代码，我需要弄清楚如何在多个容器上放置一个磁贴。 编辑希望每个容器都能读取该字母并组合成一个完整的单词

答案 0 :(得分：1)
我会考虑使用表格。您需要在表格中放置所有瓷砖，因此您正在使用 myObject的[1] myObject的[2]
等。然后你可以使用单个触摸功能，其中event.target是被触摸的对象（即，如果有人触摸了myObject [2]，将在你的函数中作为event.target引用。那么如果你的容器也在一个表中：< / p>
container[1]
container[2]
然后在你的触摸处理程序中，你可以做一个循环：
for i = 1, #container do
-- do your code to check to see if your object is in your container
end
你应该能够通过使用event.target是你的磁贴和循环容器这一事实的组合来逃避单个触摸处理函数，这样你就可以对所有这些进行测试。
