我可以“反转"一个布尔值吗?

Can I #39;invert#39; a bool?(我可以“反转一个布尔值吗?)

问题描述

我有一些检查以查看屏幕是否处于活动状态.代码如下所示:

I have some checks to see if a screen is active. The code looks like this:

if (GUI.Button(new Rect(Screen.width / 2 - 10, 50, 50, 30), "Rules")) //Creates a button
    {
        if (ruleScreenActive == true) //check if the screen is already active
            ruleScreenActive = false; //handle according to that
        else 
            ruleScreenActive = true;
    }

有什么方法可以 - 每当我点击按钮时 - 反转 ruleScreenActive 的值?

Is there any way to - whenever I click the button - invert the value of ruleScreenActive?

(这是 Unity3D 中的 C#)

推荐答案

你可以通过否定布尔值来摆脱你的 if/else 语句:

You can get rid of your if/else statements by negating the bool's value:

ruleScreenActive = !ruleScreenActive;
