英文:
What is the difference between these two examples of code?
问题
以下是您要翻译的内容：
我已经在过去的一年中在各处都在使用While GetKeyState("<some key>", "p")，而没有真正思考实际发生了什么。
space::
While GetKeyState("space", "p")
{
MyVar++
Tooltip, % "MyVarIs: " MyVar
Sleep 500
}
上面的Tooltip命令是否只触发每半秒一次？
如果是这样，那么以下代码是如何工作的？因为没有Sleep 500：
space::
if GetKeyState("space", "p")
{
MyVar++
Tooltip, % "MyVarIs: " MyVar
}
我认为它应该只触发一次。要再次触发，我必须释放并再次按下Space键，但事实并非如此。Tooltip命令会持续触发，就像在While示例中一样。
感谢任何帮助。
英文:
I have been using While GetKeyState("<some key>", "p") everywhere for best part of a year without really thinking about what is actually happening.
space::
While GetKeyState("space", "p")
{
MyVar++
Tooltip, % "MyVarIs: " MyVar
Sleep 500
}
Is the above Tooltip command, essentially only triggering every half a second?
if so then how is the following working? Since Sleep 500 is absent:
space::
if GetKeyState("space", "p")
{
MyVar++
Tooltip, % "MyVarIs: " MyVar
}
I am thinking it should only fire once. To fire again I have to release and press Space again, but that is not the case. The Tooltip command continuously fires just like in the While example.
Thanks for any help.

得分: 1
第一个提示命令每半秒触发一次，因为有 Sleep 500。
第二个命令在按住键时持续触发：
space::
; if GetKeyState("space", "p") ; 多余的
; {
MyVar++
Tooltip, % "MyVarIs: " MyVar
; }
return
要使其仅在释放键时触发一次，请使用 Up 变体：
space Up::
MyVar++
Tooltip, % "MyVarIs: " MyVar
return
或者使用 KeyWait 命令。
英文:
The first Tooltip command is triggering every half a second because of Sleep 500.
The second is continuously triggering if the key is holding down:
space::
; if GetKeyState("space", "p") ; redundant
; {
MyVar++
Tooltip, % "MyVarIs: " MyVar
; }
return
To make it fire only once (by releasing), use the Up variant:
space Up::
MyVar++
Tooltip, % "MyVarIs: " MyVar
return
or the KeyWait command.
