im使用unity 2018和c＃ 我想检查我的布尔值是否正确。这是 我的代码：
public class ShopButtonClick : MonoBehaviour
{
bool shopOpened = false;
public GameObject upgradeone;
public void ClickTheButton()
{
if (shopOpened)
{
shopOpened = false;
upgradeone.Setactive(false);
}
else
shopOpened = true;
upgradeone.Setactive(true);
}
}
问题是它不起作用，我将脚本添加到了按钮上，但它不起作用，在我的其他项目中它可以正常工作...但是由于某些原因，现在不行。
您缺少括号：
if (shopOpened)
{
shopOpened = false;
upgradeOne.SetActive(false);
}
// without brackets the else only applies to the first line of code after it
else
shopOpened = true;
// This is always executed
upgradeOne.SetActive(true);
您想要的可能是
if (shopOpened)
{
shopOpened = false;
upgradeOne.SetActive(false);
}
else
{
shopOpened = true;
upgradeOne.SetActive(true);
}
事实上，我宁愿简单地写为
public void ClickTheButton()
{
// invert the bool flag
shopOpened = !shopOpened;
// directly re-use its value
upgradeOne.SetActive(shopOpened);
}
在else之后您缺少大括号。
尽管您可以编写不带括号的if / else语句，但仅将else之后的第一行视为else语句的属属。
对于您而言，这意味着upgradeOne.SetActive(true);将始终被排除，因为它将被解释为。
if (shopOpened)
{
shopOpened = false;
upgradeOne.SetActive(false);
}
else
{
shopOpened = true;
}
upgradeOne.SetActive(true);
我总是会加括号以完全防止此类错误。
