Help Making Toggle Loop Topic is solved

[toxicxarrow]

Hello, I'm trying to make a script in AutoHotkey that toggles "scroll lock" on and off every 750 milliseconds with the press of a key combination (ctrl+alt+i). If I press it again, it stops the loop. This is what I have so far:

Code: Select all

Ctrl-Alt-i::
Toggle := !Toggle
loop
{
    If not Toggle
        break
    scrollLock
}
return

Any help would be appreciated.

Code: Select all

#NoEnv

^!i::SetTimer, MyLoop, % (Toggle := !Toggle) ? 750 : "Off"

MyLoop:
    Send, {ScrollLock}
return

Thank you so much. That's exactly what I needed.

Hey this is a nice way to boost versatility of settimer. Its not clear in docs that u can expand the period parameter like this. Could you please comment on it?

This is nothing limited to SetTimer - you can use the ternary operator in a lot of cases to replace a simple if-else-comparison:

?: Ternary operator [v1.0.46+]. 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 should become its final result. For example, var := x>y ? 2 : 3 stores 2 in Var if x is greater than y; otherwise it stores 3. To enhance performance, only the winning branch is evaluated (see short-circuit evaluation).

But here it was combined with the possibility of forcing an expression: https://autohotkey.com/docs/Variables.htm#Expressions (at the end of the section)
