Question

我做了一个鼹鼠风格的游戏，我正在使用mousePressed（）方法来敲击鼹鼠。代码工作正常，唯一的问题是有一种破坏游戏的漏洞利用，只需按住鼠标即可完成。基本上不是每次点击鼠标而只是按住它来获得每个痣。为了尝试解决这个问题，我使用了mouseClicked（） - 相同的问题。这可能是由于我在mousePressed（）中的布尔值，但我不知道，因为我在另一个游戏中有类似的问题，我编码的地方没有布尔变量。我希望游戏能让你每次想要敲击鼹鼠，任何解决方案都要点击吗？我考虑使用计时器而不是故障排除，我刚刚来到这里3个小时。谢谢 - 这是代码：

Answer 1

MouseReleased具有longPress的优势。由于发布事件将是鼠标单击的最后一个事件（按住，释放）。你必须使用

 mouseReleased(MouseEvent e)

代替。这适合您的情况。

https://docs.oracle.com/javase/7/docs/api/java/awt/event/MouseListener.html#mouseReleased(java.awt.event.MouseEvent)

Answer 2

mousePressed每次按下后调用一次，mouseRelease在每次发布后调用一次。如果在mousePressed上设置布尔值为true而在mouseReleased上设置为false当然，操作取决于您的mouseP变量将触发多次，直到您释放按钮为止。

如果您希望每次按下调用一次操作，为什么不使用：

mousePressed() {
    if(someKeyIsPressed) {
        // fire hit or whatever you want
    }
}

像这样的事情。 mousePressed中的操作每次按下只会执行一次。压缩释放后调用mouseClicked。它也可以工作，所以Gaurava Agarwal所提到的产品也是如此，但是当你释放按钮时做游戏的游戏很奇怪并不常见。想象一下fps游戏，你可以在按钮释放时进行拍摄。

处理：mousePressed（）/ mouseClicked（）经常打勾
