我一直在研究应该是一款相对简单的游戏 Mormon Sim。目标是在挨家挨户进行时进行成功的对话。这非常简单，只需单击一个按钮，它就会根据调用的按钮和方法更改 JLabel 的文本。例如，使用敲门按钮将激活方法 knockResponse，该方法将计算是否有人会来敲门。根据计算结果，有人会开门，否则您将被拒之门外。问题是，在点击几下之后，通常一旦玩家通过了敲击检查，JLabel 就会开始自行恢复为其他文本，并在一些不同的事物之间来回切换，有时甚至完全无视它们上的 Swing 计时器。我真的不知道这里发生了什么，我真的找不到发生这种情况的原因。整整一周的彻底谷歌搜索没有产生类似的问题或解决方案。 TL;DR Java 已经有了 self 意识

感谢您的帮助，我不擅长提问。
最佳答案
计时器 starts out repeating ， 默认情况下。因此，您的计时器每秒都在计时，永远计时。
你应该调用setRepeats(false) :
void doLater(ActionListener action, int delay) {
Timer timer = new Timer(delay, action);
timer.setRepeats(false);
timer.start();
}
