 If you mean defaultFolder (rather than default stack), there is no
 difference: the folder, the directory, and the defaultFolder are
 synonyms.

Ahhh! I was wondering about that from reading previous posts. Thanks.

Various questions

[rand valentine]

  Hi, all. I really appreciate everyone's contributions to this list,
both those taking time to pose questions and of course those who provide
answers. I've been a HyperCard user since it was first introduced, and
have used it extensively for various linguistic-related projects. I
wrote my phd dissertation using HyperCard to organize data (a dialect
study of the North American aboriginal language Ojibwe). I am presently
teaching at the University of Wisconsin (Madison) in American Indian
Studies, seeking to help preserve the Ojibwe language (most aboriginal
languages in the world will die out in the next two generations due to
pressures of globalization). Most of my Revolution work will involve
producing stacks to help language learners. I use Mac OS9, X.1.2, and
Windows 2000. I built my first runrev language stack today, and have a
couple of questions for the group:

1. If you use a player and external sounds, is there any way to
relativize the path to the sounds? For example, I have cards that have
Ojibwe written on them, and when the user clicks on a button, my
pronunciation of the Ojibwe is heard-- via a player that finds an audio
(wav) file. But how do I generalize the paths in the players so that a
downloaded copy of the runrev stack with associated audiofiles will be
able to find the audio files without the user's having to know how to
link files? Could you use the default folder to good effect in this
case? Help!

2. How necessary is it to have external audio files? What is the size
threshold in terms of final stack size? For example, if I have a set of
say 25 audio files that are each about 50K, will it really tax a typical
Windows or Mac system to have all of these audio files embedded in a
single RunRev file (ie, overload memory to load this stack)? What
guidelines can be given as to size? This would really help novice
users.

3. To the RunRev team: We need a stack repository, where people can
upload stacks to give others ideas about developing their own materials.
This will only help Revolution thrive as a commercial product. The docs
for runrev are a great start, but they are still very limited. Stack
examples will help people with particular interests to see
implementations of projects of the sort that they themselves are
undertaking. It's funny-- runrev produces in me the same kind of
loyalty/devotion that the mac does- something about aesthetics and the
quality of life. I _love_ this program. It will help Ojibwe to survive.

Okay, enough for now. Thanks for your help, dear fellow programmers.

Re: Various questions

[yves COPPE]

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

What's the difference between setting the directory or setting the 
default stack ?
