Dear All
Please forgive yet another newbie question.
I have stack which plays a sound file played through a
playerobject. Its path is identified in the player's "Source"
property. Let's say it is C:/sounds/apl.wav.
The file plays perfectly well in the development environment and on
my computer.
I now make a standalone application - and it is produced ok.
However, my sound file can no longer be heard. Either it has not
been automatically packaged into the application or there is a path
problem.
I have tried to include the relevant file in the package by using
the "Copy Files" setting of the "Standalone application settings"
but that seems to make no difference. Is there some legible
documentation somewhere of how to prepare the files so that the
whole package gets produced correctly with the correct paths? DO I
have to respect the original paths and recreate them on any
computer which tries to run the standalone?
Andrew,
Most often it's easiest to leave the external media files in a place
relative to the defaultFolder. The problem is the default value of
the defaultFolder changes when running as a standalone vs. in the
development environment. In the IDE, the defaultFolder is the folder
containing the Revolution executable. In the standalone environment,
the stack in essence becomes the executable, so the defaultFolder is
the folder containing the standalone. If you don't explicitly set the
defaultFolder to another place on the disk, it will work if you set
the filename ("source") property of the player to 'sounds/apl.wav',
and then making sure the sounds folder is in the same folder as the
standalone. To deal with the difference between the IDE and
standalone, I often include the scripting similar to this in my
mainstack's stack script:
on preOpenStack
# set the root folder for all resources
if the environment is "development" then
set the defaultFolder to enclosingFolder(the name of me)
end if
## Do this for local data and media files.
set the baseDir of me to the defaultFolder & "/" & "resources"
end preOpenStack
function enclosingFolder pStName
get the filename of pStName
set the itemDelimiter to "/"
return item 1 to -2 of it
end enclosingFolder
The situation for Mac OS X is slighter more complicated, but easy
enough to understand, if you're interested.
One last thing... I never use the "copy files" part of the standalone
builder. I find it easiest just to build my standalone then move the
needed files or stacks into the appropriate folder.
