JLabel自行更改

Question

I've been working on what should be a relatively simple game, Mormon Sim. 我一直在研究应该是一个相对简单的游戏，Mormon Sim。 The goal is to hold a successful conversation while going door to door. 目的是在门到门的同时进行成功的对话。 It's pretty simple, on the click of a button, it changes a JLabel's text according to the button and method called. 这非常简单，只需单击一个按钮，它就会根据所调用的按钮和方法来更改JLabel的文本。 For example, using the Knock button will activate the method knockResponse, which will calculate if someone will come to the door or not. 例如，使用“敲门”按钮将激活方法tickResponse，该方法将计算是否有人来门。 Based on the result of the calculation, someone will answer the door or you will be turned away. 根据计算结果，有人会回答门，否则您将被拒之门外。 The problem is, after a few clicks, usually once the player gets past the knock check, the JLabel begins to revert itself back to other text, and back and forth between a few different things, sometimes completely disregarding the swing timers on them. 问题是，单击几下后，通常在玩家通过敲门检查后，JLabel便开始将其自身还原为其他文本，并在一些不同的事物之间来回切换，有时甚至完全忽略了它们上的摆动计时器。 I really have no idea what is going on here, and I can't really find a reason that this would happen. 我真的不知道这是怎么回事，也无法找到发生这种情况的原因。 A whole week of thorough googling has yielded no similar problems or solutions. 整个星期的全面谷歌搜索没有产生类似的问题或解决方案。 TL;DR Java has become self aware TL; DR Java已经变得自我意识

Thanks for any help, I'm terrible at asking questions. 感谢您的帮助，我很想问问题。

Answer 1

A Timer starts out repeating , by default. 默认情况下， Timer 开始重复。 So, your timers are all firing every second, forever. 因此，您的计时器永远每秒都在触发。

You ought to call setRepeats(false) : 您应该调用setRepeats(false) ：

void doLater(ActionListener action, int delay) {
   Timer timer = new Timer(delay, action);
   timer.setRepeats(false);
   timer.start();
}
