我为学校项目创建了自己版本的 cookie clicker，除了计时器之外，一切似乎都正常。我对计时器的概念很陌生，不确定我的公式是否正确。任何反馈都是有帮助的。我的计时器的公式是 双倍速度 = 1/每秒 * 1000； 计时器速度 = (int)Math.round(速度); 目的是每 0.1 秒添加一个 cookie 作为基线，并在您每秒升级 cookie 时 perSec();它增加了。当我的一些 friend 玩这个游戏时，他们意识到他们每秒获得更多的 cookies 。我想知道这是否是我的计时器的问题，或者我在 switch 语句中使用 addActionCommands 做了什么错误

最佳答案
每次调用 setTimer() 时，都会创建一个新计时器。因此，如果您调用 setTimer() 三次，则会创建三个新计时器，并且每个计时器都会继续创建 cookie。
