我想知道如何检测用户是否已经第一次,或之后的次数发布了鼠标按钮:
伪码:
if *first* (Input.GetMouseButtonUp(0))
{
do something
}
if *second, third, fourth..etc.* (Input.GetMouseButtonUp(0))
{
do something else
}
我真的不知道如何做到这一点。我相信它很简单!

这只是一个想法,但您可以使用标志变量执行此操作,如下所示:
private static bool WasFirstTimeReleased = false;
if (Input.GetMouseButtonUp(0))
{
if (!WasFirstTimeReleased)
{
WasFirstTimeRelease = true;
//do your stuff for first time
}
else
{
//do your stuff for all other times
}
}

通常,您必须记住某个按钮被释放的次数。只需在你的课程中创建字段:
private int clicks = 0;
然后:
if (Input.GetMouseButtonUp(0))
{
if(clicks == 0)
{
// do something on first click
}
else
{
// do something on further click
}
clicks++;
}
如果每次按下鼠标按钮时都会创建存储点击计数器的对象,则使用静态字标记计数器。

跟踪鼠标点击次数
int _leftUp;
void Update()
{
var leftUp = Input.GetMouseButtonUp(0);
if (leftUp) _leftUp++;
// etc ...
}

最简单的方法是使用计数器检查用户释放按钮的次数。
private int releaseCounter = 0;
然后在if语句中:
if (Input.GetMouseButtonUp(0)) {
releaseCounter++;
//If you know on which release you want the code to be executed,
//replace the x with that number.
if (releaseCounter == x) {
//your code here
}
//If you want the code to be executed at set intervals.
//replace the x with the interval number.
if(releaseCounter%x == 0) {
//your code here
}
}
希望我帮助过。
