Hi guys from conitec,

My game is ready and I have a lot of .AVI movies to play within the game.

I would like to let them on CD-ROM to avoid a lot of data on hard disk.

I'm using Install Shield to create the install CD.

I know how to do to install the game without the AVIs.

The problem is:
How can I say to the engine to seek these AVIs on cd rom, since every machine has a different letter to represent the drive?

When the player start the game, how can I do to verify if the CD is inserted into the drive?

Thanks,

This is useful topic. Could you tell me when you get some usefull replies? Thanks.

Although it's not automatic (less professional?) you could display a panel asking the user for their CDROM drive letter.
Then prepend their response to a string var that you use to play the AVIs.

Just a rough idea:

String AVImovie = " "; // 32 spaces.
String DriveLetter =" "; // A single space
String AVI01 = "://AviDir//Intro1.avi"
<Get user input to DriveLetter>
str_copy(AVImovie, ""); // set to null
str_cat(AVImovie,DriveLetter); // add the drive letter
str_cat(AVImovie, AVI01); add the path & filename.

play_moviefile(AVImovie);

I don't know if this will work....

But there has to be a better way...

Hi, A better way would be to use the new file I/O functions, to scan the drives for a dummy file in your AVI Directory structure, once you've found the file, you know where to play the AVI's from.
The handle to the file is 0, if it can't be openned.

I think Michael may already have this wrapped up for you, but, I believe most applications either write to the registry or an Ini file during the installation as to where it is being installed FROM .. this is how they get the path to these files.
