我不能倒置“一个布尔值? [英] Can I 'invert' a bool?
本文介绍了我不能倒置“一个布尔值?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一些检查,看是否有画面激活。代码如下:
如果(GUI.Button(新矩形(Screen.width / 2 - 10,50,50 30),规则))//创建一个按钮
{
如果(ruleScreenActive == true)而//检查屏幕是否已经激活
ruleScreenActive = FALSE; //根据该
,否则
ruleScreenActive =真正的处理;
}
有没有什么办法 - 每当我按一下按钮 - 反转的价值 ruleScreenActive
?
(这是Unity3D C#)
<$ C $:h2_lin>解决方案
您可以通过否定布尔值摆脱你的if / else语句C> ruleScreenActive = ruleScreenActive!;
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;
}
Is there any way to - whenever I click the button - invert the value of ruleScreenActive
?
(This is C# in Unity3D)
解决方案
You can get rid of your if/else statements by negating the bool's value:
ruleScreenActive = !ruleScreenActive;
