- Why use this? Well, it's Mac-only, but it'll allow a few Good Things to happen:
- ΓÇó We get the System Folder for placing a Prefs file..
- ΓÇó We can determine whether the game is currently being run from the CD or not,
- suggesting that the user copy one or more files to the HD (doing it from
- within the Projector, and keeping track of what goes where)
- ΓÇó Setting the current fileIO path wherever we like, for checking out which files
- end up where.. including game assets AND user's saved games
-
- set util = MovieUtilities( mNew ) --creates the object...
-
- put util( mGetVolName, the pathName ) --tells you which volume the Projector is playing from..
- -- "xxJumbo:"
-
- put util( mGetSystemPath ) --gives the "blessed" system folder; put Prefs in the "Preferences" folder if
- -- "Pluto:System Folder:" -- it exists (see error msg below), or directly in the System folder if it doesn't...
-
- put util( mSetDefaultPath, util( mGetSystemPath ) ) --this sets the default fileIO path to the current system path..
- -- 0
-
- put testio = fileIO( mNew, "?read","") --This is standard means of popping up a fileIO dialog box.. confirms that above works!
- -- 0
-
- --OK, so this will try to set the path to the "Preferences" folder; if that doesn't
- -- exist, it'll fall back to the 'sure thing': the System Folder itself.
- if util( mSetDefaultPath, util( mGetSystemPath )&"Preferences:" ) = -43 then ¬
- util( mSetDefaultPath, util( mGetSystemPath ) )
-
- --Similarly, when we try to open an existing Prefs file, we should first check the System folder, then the Preferences folder..
-
- -- extract volume name from a given path name string:
-
- on getVolName
-
- global utilObj
-
- if objectP( utilObj ) then
- put utilObj( mGetVolName, the pathName ) into field "displayPath"
- else
- alert "Sorry...no object has been created"
- end if
-
- end getVolName
-
- -- returns complete volume and pathName of currently active System folder
- -- as a string...useful for creating/opening Prefs:
-
- on getSysPath
-
- global utilObj
-
- if objectP( utilObj ) then
- put utilObj( mGetSystemPath ) into field "displayPath"
- else
- alert "Sorry...no object has been created"
- end if
-
- end getSysPath
-
- -- Set the default pathName of "volume:folder(s):" so that
- -- with FileIO "?read" permission, the SFGet() Dialog opens to the
- -- specified folder. This does not affect the Lingo pathName property.
- -- Only tested on System 7.x.

- else if result = -43 then
- alert "No such folder exists. Please try again..."
- else if result < 0 then
