Datafiles are pretty easy to use and make. With Allegro there comes a program named GRABBER.EXE wich you can find in your Allegro\tools- directory. Run it and start creating your own datafile. That's not difficult either: just press the right mouse-button on the big box, where is at the top and select from the popup-menu NEW and the type of thing (ex. bitmap or midi) you want to add. Then you have to name it. The name appears in the box. After that you can grab a sound to it pressing the right mouse-button on the name and by selecting GRAB. Bitmaps are a bit different: before you can grab a bitmap you've got to load a PCX or BMP- file in using the Get Bitmap- command in the FILE-menu. Then you can grab the same way as the other stuff. More info you can find in the Allegro documentation. Using datafiles in your programs is well explained there too, so I think you can find that there. If you can't, ask again. Datafiles are great, enjoy them! > and also > how would i retrieve the info from the file with my program? I'm sorry but I'm not sure if understood this question right, but here's what I think. So, do you mean the info about the datafile? If so, you must in the GRABBER-program add at the line HEADER at the top, a name for a header, for example test.h. When you save the datafile, grabber also makes a header wich includes the names (the names you gave them) of the stuff in the datafile as #defines. You can use those names in your program to present the bitmaps and sounds etc. in the datafile. If this wasn't what you asked, I'm sorry. But be brave and ask again. -- ---------------------------------------------------------------------------- Jarkko Laine e-mail: Jarkko DOT Laine AT ks DOT iwn DOT fi WWW: http://www.geocities.com/SiliconValley/Peaks/7734/ ---------------------------------------------------------------------------- -
