FLASH: Endless Loop w/two MC's (action script)

Eric,

I don't want to do that (considered it), because I don't want to

'hardwire' this movie clip like that.  In other words, I don't always

want frame 22 to back up and look for another target.  I want it more

re-useable than that.  After all, that's part of the appeal of

Flash...the re-usability of symbols.  If I hard code a frame action

like that, I lose that.  I've done it in other instances like you

suggest, but I don't want that here.


Mark,

started to

>tell target the other clip?


See above...

>   Play


That's what I also thought of doing and will most likely do.  It's

the programmer in me that asks why this doesn't work.  From a logical

standpoint I still don't see why it shouldn't...That would lead me to

ask then...(and maybe someone from MM can best answer this), where

when and how would the 'loop while' be best used if not in watching

frames increment on a target movie clip? 


I once used while to wait for a value to return from a

cgi/authentication script.  I cleared a variable or preset it to

something obfuscated and then loaded variables into location.  While

that value was blank/obfuscated..the script just sat there and waited

in a while loop.  When a value was returned from the cgi (success or

failure), it hit an if and forked off accordingly.  Don't know why

this doesn't work now.  Wish I had that sample in front of me (on my

computer which is currently in storage).  Anyway...


Thanks guys,


Jason
