Help ! ;-)
Of course you can use relative paths.
Here's how to:
Supposed you have your stacks etc in a big folder called "Dunno" ;-)
You could create a subfolder in that folder and call it e.g. "soundz"
(sic ! ;-)
Now you have to tell MC/RR to set its working directory, which is
the folder, where the engine will look into and will find all the nice
things in there, like stacks, movies, subfolders etc...
Now you should add these lines to the stack (inside folder "Dunno")
where you want to use relative paths:
on preopenstack ## so it's already set, when the stack starts...
get the effective filename of this stack
set the itemdel to "/"
delete last item of it
set the directory to it
end preopenstack
"the efective filename" returns the complete path to that stack with
HD etc... -> "C:/windoze/my_folder/your_folder/our_stack.rev"
Now we set the itemdelimiter to "/" (which is the default path delimiter in
MC/RR), delete the last item of "the eff..." and what's left is the complete
path to the folder "Dunno". ("C:/windoze/my_folder/your_folder")
NOW you can script something like:
on xxx
set the filename of player "playa" to "soundz/new.wav"
end xxx
Now you can just create new players and assign a filename to them like
above:
sounds/sound.wav

MC/RR uses to load an entire stack into memory !!!
So it is always a got idea to use referenced sound and movies...
I once read the advice to create no stack bigger than 3 to 4 mb.
Sounds reasonable to me, but depends on hardware configurations...

There is a usercontribution section on the RR-site.
But i don't know how to post stacks there.

Hope this helps in the moment and that my explanation is understandable :-)
