checking for the existence of a global variable, continuous play vs. single play (code included)

[Jeff]

I have a director application that I'm working on. There's a version that's
called "full play" that basically is a copy of the interactive portion, just
linear. The client wants to also have the option of "continous play".

My idea was to set a global variable when "continous play" was clicked so
that when the person clicked the button, it'd just go to the full play
frame, and go to the end, then just check at the end for the existence of
the variable, and if it was set to on.

I've got the button working fine, so that if you select "continuous" it sets
a global variable called gContinuous and sets it equal to "on". When I'm in
Full Play mode now and go to my message window, "ShowGlobals" returns my
global all nice and pretty.

Now, on the last frame of the full play, there's a bit of lingo that does
the following:

on enterFrame me
if sound(1).isBusy() then
go loop
else
go next
end if
end enterFrame

What I'd LIKE to do is change that to something like this: (my addition in
caps)

on enterFrame me
if sound(1).isBusy() then
go loop
else
IF THE CONTINUOUS GLOBAL IS "ON" THEN
go frame "full_play"
ELSE
go next
END IF
end if
end enterFrame

The error I get is that I'm trying to use the variable before it's defined,
but I'm scoping it with "global.gContinuous"....(see actual code below)

on enterFrame me
if sound(1).isBusy() then
go loop
else
if global.gContinuous = "on" then
go frame "full_play"
else
go next
end if
end if
end enterFrame

Any ideas on what I might be doing wrong?

You must declare the global at the head of the script.

You need to declare it in any and every script you want to use them by
putting a

global gContinuous

before you want to use them. Then you can just refer to it as plain old
gContinuous. Foxed me at the beginning; I thought you only needed to do a
'global gMyGlobalVariable' declaration once in a project, but no, you have
to do it in every separate script...

So...even if I declare it in the first frame of the movie, and set it = to
"off". If I want to simply check for this variable later on someplace, I
first need to declare it in the script that I'm going to check it in?

So on my script:

on enterFrame me
if sound(1).isBusy() then
go loop
else
if global.gContinuous = "on" then
go frame "full_play"
else
go next
end if
end if
end enterFrame

all I need is to change it to this?:

global gContinuous
on enterFrame me
if sound(1).isBusy() then
go loop
else
if global.gContinuous = "on" then
go frame "full_play"
else
go next
end if
end if
end enterFrame

Apparently so! Thanks for the help, worked like a charm.
