的AutoHotkey - 递减变量每秒一次

Question

我不是一个AutoHotkey的大师，而我在与递减可变麻烦，如果是大于0每秒一次：

Loop 
{ 
If spaceFreq > 0 
    spaceFreq-- 
If returnFreq > 0 
    returnFreq-- 
Sleep, 1000 
} 

这有什么问题脚本？变量没有被减少。

Answer 1

to decrement a value and store the result back in the same variable directly, 
you must do 
ex: Var := --x instead of Var := x-- 
because --x decrements X immediately and then assigns its value to Var 
x-- increments X only after assigning the current value of X to Var consequently, 
not modifying the original variable, if no variable is specified.

例如：

#Persistent 
SetTimer, decrementlabel, 1000 ;1000 ms = 1 second 
return 

decrementlabel: 
If spaceFreq > 0 
    --spaceFreq 
If returnFreq > 0 
    --returnFreq 
return
