Question

我想从使用变量的整数作为数组索引的数组接收字符串。但它不起作用。

尝试 1

; Suspended | 0 = No, 1 = Yes
global Suspended     := 0
global SuspendedMsg  := ["The script has been paused.","The script has been re-activated."]

Pause::
    Suspend
    if suspended = 0 ; If script is not suspended
    {
        TrayTip, Paused, SuspendedMsg[Suspended], 3
        Suspended++
    } else ; If it is suspended
    {
        TrayTip, Activated, SuspendedMsg[Suspended], 3
        Suspended--
    }
return

尝试 #1 只会显示字符串 "SuspendedMsg[Suspended]"，因为我不知道在哪里设置变量指示符 %。即使我将它设置为 SuspendedMsg[%Suspended%]，它也会显示 [1] 或 [0]。

尝试 2

; Suspended | 0 = No, 1 = Yes
global Suspended      := 0
global SuspendedMsg   := ["The script has been paused.","The script has been re-activated."]
global SendSuspendMsg := SuspendedMsg[Suspended]

Pause::
    Suspend
    if suspended = 0 ; If script is not suspended
    {
        TrayTip, Paused, %SendSuspendMsg%, 3
        Suspended++
    } else ; If it is suspended
    {
        TrayTip, Activated, %SendSuspendMsg%, 3
        Suspended--
    }
return

尝试 #2 效果不佳，它甚至不显示任何消息。我尝试在 global SendSuspendMsg := SuspendedMsg[Suspended] 变量中用 % 摆弄 arround 但它不会做任何事情。有人愿意帮助我吗？

Answer 1

而不是TrayTip, Paused, SuspendedMsg[Suspended], 3或TrayTip, Paused, SuspendedMsg[%Suspended%], 3，试试

TrayTip, Paused, % SuspendedMsg[Suspended], 3

。 TrayTip 要求您提供

specify the message to display

这相当于一个字符串。因此，变量名称在这里不作为变量处理，而是作为字符串处理（大多数时候在命令中）。声明 TrayTip, Paused, %SuspendedMsg[%Suspended%]%, 3 是有意义的 , 但不能嵌套变量的百分号。所以，我们必须使用百分号来强制表达式：

Force an expression: An expression can be used in a parameter that does not directly support it (except OutputVar parameters) by preceding the expression with a percent sign and a space or tab. In [v1.1.21+], this prefix can be used in the InputVar parameters of all commands except the traditional IF commands (use If (expression) instead). This technique is often used to access arrays.

关于你的第二个问题：我不认为数组可以那样声明，他们可以..？（但我不确定）。另见 this 短文。所以我猜问题出在你代码的第 3 行，因为其余部分对我来说看起来不错

Answer 2

@Blauhim 漏掉了一个重点，虽然他的回答大部分是正确的。首先像你一样创建数组中的索引，总是从 1 开始，然后继续到 2 等等......所以当你试图使用你的布尔变量来调用索引时你的代码是有缺陷的 0 索引确实不存在（更不用说你没有在那个 TrayTip 命令上强制和表达）。

; Set our variable to 1 why? Because we are going to use a Logical switch below.
Suspended     := 1
; This was correct format and I left it, although I removed Global's as they are not needed
SuspendedMsg  := ["The script has been paused.","The script has been re-activated."]

Pause::
    ; Suspend toggles each time it's called
    Suspend

    ; Here we are toggling the value of our variable using !
    ; We started with a 1 so that it would be correctly
    ;Changed to a 0 for the code below.
    suspended := !suspended

    ; Nothing changed here
    if suspended = 0 ; If script is not suspended
    {
        ; In order to pass an Array or Object or Expression to a Command you Force it
        ; using the a Percent Sign with a space on either side.
        ; Also note you were trying to use your Logical True/False 0 or 1 variable to         
        ; itterate. This didn't work because Array's always start with an Index of 1. 
        ; Below I've accounted for this by simply added a 1 to your suspended so it correctly 
        ; points to the Index in our Array.
        TrayTip, Paused, % SuspendedMsg[suspended + 1], 3

    } else ; If it is suspended
    {
        TrayTip, Activated, % SuspendedMsg[suspended + 1], 3        
    }
return
