使用GetKeyState()和循环 [英] Using GetKeyState() and loops

问题描述

我正在尝试编写一个具有循环的脚本，其中每两秒钟按下一次向上箭头键.当我按下空格键时，必须激活该循环，而当我再次按下它时，必须将其禁用.我现在正在使用它.

I'm trying to write a script that has a loop in which the upper arrow key is pressed every two seconds. The loop must be activated when I press the spacebar and deactivated when I press it again. I'm now using this.

$Space::
if GetKeyState("Space", "P")
{
    Loop
    {
        Sleep 2000
        Send {Up}

        if GetKeyState("Space", "P")
        {
            return
        }
    }
}

由于某种原因，循环内的if条件不起作用，即我无法退出循环.我希望有人能帮助我...

For some reason, the if condition inside the loop doesn't work, i.e. I can't get out of the loop. I hope anyone can help me out...

推荐答案

您不需要第一个if GetKeyState("Space", "P")
并且当循环到达第二个循环时，您将需要保留空间
使其破裂；并且您需要将return替换为break.

You wouldn't need the first if GetKeyState("Space", "P")
and you would need to be holding space when the loop got to the second one
for it to break; and you would need to replace the return with break.

尽管我会这样写，但我同意加里:

However I agree with Gary, although I would write it like this:

; (on:=!on) reverses the value of variable 'on'
; the first press of space reverses on's value (nothing) to something (1)
; the second press reverses on's value from (1) to (0)
; when (on = 1) delay will be set to 2000, and Off when (on = 0)

space::SetTimer, Action, % (on:=!on) ? ("2000") : ("Off")

Action:
Send, {up}
Return

％开始一个表达式.

?:
三元运算符
该运算符是if-else语句的简写替代.
它评估左侧的条件以确定
它的两个分支中的哪个将成为最终结果.
例如，var:= x> y?如果x大于y，则2:3将2存储在Var中；否则x大于y.否则将存储3.

?:
Ternary operator
This operator is a shorthand replacement for the if-else statement.
It evaluates the condition on its left side to determine
which of its two branches will become the final result.
For example, var := x>y ? 2 : 3 stores 2 in Var if x is greater than y; otherwise it stores 3.
