- Making a Slideshow disk
-
- This final tutorial deals with making a Slideshow disk. This is a simple
- disk that displays a sequence of pictures in order and is very common in the
- Public Domain. The first step is to make a drawer on Tutorial: called
- Pictures. You already know how to make a new drawer so do it now...
-
- ...OK? Now load DPAINT or something and create five pictures. If you
- can't draw, use some of the example pictures. Save them in the Pictures
- drawer of Tutorial with the names Pic1, Pic2 ... Pic5.
-
- ...Finished? Now copy the picture viewer Vilbm from the C drawer of
- C.L.Index to the C drawer of Tutorial. Don't forget you can use C: to
- specify the C.L.Index C drawer if you booted from that disk. And don't
- forget to copy files to RAM: first to speed up copying.
-
- ...Have you realised how much you can do on your own? So far I haven't
- given you anything to type - you've done it all yourself!
-
- Now it is time to introduce another command - Delete. You use this to
- remove files or drawers you no longer need. You are going to delete the
- file message. So type
-
- Delete Tutorial:Message
-
- and the computer will announce the file is deleted. Be careful with
- delete because you cannot get back what you delete. Now it is time to
- print or write out some instructions.
-
- ******START
-
- Use Ed to edit Tutorial's file S/Startup-sequence. you already know how to
- do this. Delete the line that is already there and type in these lines.
-
- Echo "Slideshow disk by <your name>"
- Echo "Press left mouse to go onto next picture"
- Vilbm Pictures/Pic1
- Vilbm Pictures/Pic2
- Vilbm Pictures/Pic3
- Vilbm Pictures/Pic4
- Vilbm Pictures/Pic5
- Echo "Slideshow finished... Bye!"
-
- Save the file then quit.
-
- ********END
-
- Echo is a special command used by AmigaDOS to type some text to the screen
- without having to make a file and use Type. The problem is you can only
- do one line at a time this way. Read the final checklist then try out the
- disk. Now try reading the rest of C.L.Index and see how much you can
- understand.
-
- Checklist
-
- Now you can...
-
- o Use Vilbm to show a picture
- o Make an autobooting Slideshow disk
- o Delete unwanted files
- o Use all the commands in the tutorial
-
- Now you can try making many more autobooting disks using many more CLI
- commands. How about a disk that tells you the title of each picture as it
- loads? Or how about using the Run command with a player and play some
- music? the possibilities are almost endless. Have fun!
