| So I'm trying to use variables to do some different things, but I'm having a problem with variables not updating. When I use the following code, it always notes the variables as the same thing even though I have changed the variable to a new thing.
SetVariable("thing", "1")
Note("@thing") -- shows 1
SetVariable("thing", "2")
Note("@thing") -- shows 1
then when I run that again, both notes show as 2 instead of one. How do I get the proper numbers to show? | | Top |

| Nobody should ever use the @thing notation for variables inside script code, because basically nobody understands what it actually does, what it's for, and when to not use it.
Use Note(GetVariable("thing")) instead and it will do what you expect. |

| What if I wanted to update the variable and then run an ifcheck on it right after? How would I get that to work correctly?
SetVariable("thing", "1")
if @thing == 1 then
Send("dosomething")
end
Wont this also not work correctly? | | Top |

| The expanding of variables is done at the start of
script execution. Thus, changing a variable and testing it in the same
script will always return the original variable contents.
So this won’t work:
SetVariable("thing", "1")
if @thing == 1 then
Send("dosomething")
end
This will:
SetVariable("thing", "1")
if GetVariable ("thing") == "1" then
Send("dosomething")
end
Note that variables are stored as strings, not numbers, which is why
I quoted the “1”.
What is easier anyway is to use Lua variables, if you don’t need them
to persist from one session to another, ie.
thing = 1
if thing == 1 then
Send("dosomething")
end
