- Please read this if you intend hacking around with !Aquarium:
- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
-
- The first problem you are likely to encounter is that of
- changing/altering the sprites:
-
- DECOMPRESSING THE SPRITES FOR EDITING WITH !Paint:
- ==================================================
- To decompress the sprites for editing in !Paint, edit
- the !RunImage, and look in PROCinitsprites for the point
- where there is a CALL command. After this, place the
- line:
- SYS "OS_SpriteOp",256+12,spr%,"$.!Aquarium.Sprites":END
- Now, run !Aquarium, and (if you have >110kB free on
- your disc) you should have the original sprite file in
- the !Aquarium.Sprites. This file can also beconverted
- back simply by running the 'PackSprite' program. See
- below.
-
- RE-COMPRESSING THE SPRITES FOR USE IN !Aquarium:
- ================================================
- In the !Aquarium directory, you will find a small BASIC
- program called 'PackSprite'. This attempts to pack the
- sprite file called '$.!Aquarium.Sprites' into a file
- called '$.!Aquarium.PackedSpr'.
- MAKE SURE YOU ONLY RUN THIS USING A BACKUP COPY OF !Aquarium!
- Then, you must alter the !RunImage program: It
- decompresses the sprites in a procedure PROCinitsprite.
- The 2 important things to check here are:
- 1) Have I got enough space reserved to hold the
- decompressed sprites?
- 2) (look for the line marked with **** in a REM) Have
- I put the correct 'Original Sprite size' value into the
- correct variable?
- You will know when you have got these wrong, 'cos the
- desktop will crash horrendously!
- Now if any errors occur, they are most likely due to
- too small a WimpSlot value. (Especially if you have
- compiled the !RunImage)
-
-
- To compile !Aquarium:
- =====================
- RiscBasic likes the !RunImage, and you only need to
- remove the 'END=END+xxxx' line near the start of the
- program for it to compile happily.
- ABC 2 doesn't like it at all! (I got it to compile,
- but it never ran)
-
-
- Yo! Keep reading!
- =================
- Also, if you make any good improvements to this
- application, have any new ideas for Aquarium-
- based animation or other animations, or write
- your own animation for use with this, PLEASE
- send me a copy to look at!
- (Ideas at present include 'Dolls House', 'Ant Farm',
- and 'Aviary' (Bird cage))

- P.S. If anyone is willing to donate a 30MHz ARM-3, I
- would really really really like to write a 30MHz (and
- 12MHz) it'll-blow-you-away version!! (hint hint)
