Director Help Creating Projectors

DirectMediaXtra icons operate only under Windows 95, 98, ME, Windows NT 4 and Windows 2000. Please check our web site at http://xtras.tabuleiro.com for updated information about system requirements for different operational systems. You should create your Projectors for Windows 95 and Windows NT, and with the "Animate in Background" option checked. To prevent problems with palettes you should include with each projector a copy of the modified DIRECTOR.INI file you created following the instructions in the Getting Started section. The .ini file should be renamed to match the name of the Projector, i.e.:

Projector: myproj.exe
.INI file: myproj.ini

The Xtra is automatically included in the Projector if your first movie contains a DirectMediaXtra cast member. If you are creating a "dummy" projector that will call your .dxr movie, you can include the Xtra in the Projector using the MODIFY->MOVIE->XTRAS menu, and adding the DirectMediaXtra.x32 file.
TIP: You can also deliver the DirectMediaXtra.x32 file in a folder named XTRAS, located in the same directory of your Projector, if you do not want to embed the file into your projector. This is recommended for faster startup of your Projector, and for delivery on the NT platform.
We also recommend including a LINGO.INI file with your Projector. This file should contain the following code to prevent problems playing sounds when Intel RSX and DirectSound are installed:

on startup
set the soundkeepdevice to 0
end startup

The final structure of files should look like:
Projector - C:\myproj\proj.exe
.INI file - C:\myproj\proj.ini
Lingo.ini - C:\myproj\lingo.ini

Optional (if Xtra was not embedded into the Projector):
Xtra file - C:\myproj\Xtras\DirectMediaXtra.x32

The Xtra will automatically locate all linked Media files that are located in the same directory of the Projector. Additional directories can also be specified using the SEARCHPATHS list attached to each DirectMediaXtra castmember. This list can be edited directly from the DirectMediaXtra castmember properties dialog box and is saved with the castmember in the Director movie. Both absolute and relative directory entries may be used. Relative directories are evaluated in relation to the projector executable, while absolute directories must contain a drive letter and complete pathname information.
Examples:
Relative directory entry: media
Absolute directory entry: E:\media

When used with Director 5 and 6, the Xtra will also search all the directories listed in "the searchpaths" Lingo variable for missing Media files. The searchpaths is also evaluated before any Lingo in the current movie executes so it should be set preferably in a LINGO.INI file. The release version of Director 7 had a bug that was corrected in version 7.02, and "the searchpath" and "the searchpaths" variables were not being scanned by Director. We included special code on DirectMediaXtra to work around the searchpath bug, using a global variable named tbsearchpath. You can include the following code on your LINGO.INI file to define and add directories to the searchpath and tbsearchpath variables, specifying relative directories to hold your linked MPEG files:

DIRECTOR 5 and 6 LINGO.INI:
on startup
set the soundkeepdevice to 0
-- Added to look for files in the "media" subdirectory
append(the searchpath, the pathname & "media")
end startup


DIRECTOR 7 and 8 LINGO.INI:
on startup
set the soundkeepdevice to 0
-- Added to look for files in the "media" subdirectory
global tbsearchpath
set tbsearchpath=[]
append(tbsearchpath, the applicationPath & "media\")
append(the searchpaths, the applicationPath & "media")
end startup

You can safely put your Media files in the "media" subdirectory (C:\myproj\media in the example above) and the Xtra will automatically find them when the Projector starts.
