- LADDERS README.TXT
-
- To run 'Ladders' you will need VGA video and the following files:
- LADDERS.EXE - the main program
- LADDERS.PAL - color palette for Ladders
- LASPRITE.LIB - all the sprites for ladders
- LATILE.LIB - background tiles
- MODERNFO.FNT - a font file
-
- Using a sprite maker program by Kai Rohrbacher called 'MAKES', you can
- make a personal copy of ladders with your own sprites! You will need
- SuperVGA video and these additional files:
- MAKES.EXE - the sprite maker program
- MAKES.DOC - documentation for MAKES
- UNLIB.EXE - extracts sprites from a library
- BFFFFFFF.EXE - compression/decompression program
- SVGA256.DRV - a SuperVGA driver
- You can extract the sprites in LASPRITE with:
- UNLIB LASPRITE.LIB
- This will give you 131 files, UNLIB000.COD TO UNLIB130.COD which you can
- load into MAKES and modify or replace. Starting with UNLIB041.COD you have
- 45 pair of blockers and carry items required to remove them. UNLIB041.COD
- is a door and UNLIB042.COD is a key. You may not want to change these but
- any of the follow pairs might be replaced with your own drawings. Carry
- items should be centered in a 40X16 pixel rectangle so they show up
- correctly in the carry window. Blocker items should be left justified with
- their feet 40 pixels from the top.
- When you have the pairs changed as you want them type:
- COPY /B UNLIB???.COD LASPRITE.LIB
- The 131 files will be recombined into a new library. Run LADDERS and check
- out your work. IF you want to save some space, compress the library:
- BFFFFFFF LASPRITE.LIB LASPRITE.TMP C
- Rename or delete lasprite.lib and then rename lasprite.tmp to lasprite.lib.
- You can also change tiles used to make the background by following a similar
- process with LATILE.LIB. In this case you get 18 COD files, 001 - 015 are
- the 15 background tiles for the 15 different levels. COD files for tiles
- have to remain at 16X16 pixels.
-
- I've include the source code in case you want to see it or modify it. To
- recompile you will need Turbo Pascal 6.0 or higher and the TPU units
- ANIVGA.TPU and MUSIC.TPU. These are available in the ANI-VGA package by
- Kai Rohrbacher. It can be found on a Simtel20 mirror as ANIVGA12.ZIP.
- I got it from oak.oakland.edu /pub/simtel/msdos/turbopas. Note that the
- music.pas file (by J.C. Kessels) has been modified for the game included
- with ANI-VGA. The numbers changed appear in 'PlayMusic' and 'Initialize'
- with the original numbers, (correct), in braces.
