it's the only way to approximate them. as jd said, there are no real globals

in flash. there really aren't any locals either in the normal sense of a

variable that's only defined for the duration of a function.

>from setting up temp text fields to write to?

several methods:

1) use control>>list variables at any time during test movie mode

2) use control>>list objects also during test movie mode

3) use the trace action. trace will send the results of an expression or

string to the output window during playback in test movie mode. in a movie if

you want to know that frame 5 had been reached, you could put a trace action

on that frame with a string literal value of "hi there". then "hi there"

would be displayed in the output window in test movie mode when frame 5 was

hit. apply trace as necesarry to output the value of a variable or message.

note though that it must be set to expression (the two lines under the abc

button) if you want to send the interpreted value of a variable. to send both

a message and a variable, set to expression, then use something like this:

trace("number of objects is currently: " &numObj)

yup. it also has to be named.


> And is the root still referred to as _level0?

yup again. note that a variable stored on the main timeline called "foo"

would be referred to like this:


/:foo


a bit odd, but logical.


cheers,
