- Readme for Map Creator:
-
-
- This is a brief guide to using Map Creator, a demonstration of the Midwinter
- mapping technique described in ACE Magazine, Issue 37.
-
- Requirements:
-
- Amiga (No!)
- AMOS or AMOS Pro (I don't have Easy AMOS so I don't know if this will work)
-
- Place the MapCreator.AMOS and MapCreatePalette.ABK files in the same directory.
- Then load and run MapCreator.AMOS from your AMOS interpreter.
-
-
- Upon running the program you should see a black screen with a prompt for a
- seed value. The more observant may notice that the prompt moves up and down
- as you move the mouse. Gee, the wonders of multiple screens!. Basically the
- prompt is on a small hires screen overlaid on the background lowres screen,
- but since both are currently cleared to black you can't make this out.
-
- Enter a seed value, or just hit return to use the current seed shown.
-
- Sit back and wait for the program to finish generating the map. The current
- operation is shown at all times on the status screen, and when the map is
- finished, the time taken for each operation, in minutes and seconds, is
- displayed.
-
- For your information:
-
- Running on a A4000/030/882 25MHz, the timings for the default seed are:
-
- AMOS 1.36: AMOS Pro 1.12:
- Build Map : 0.29 Build Map : 0.31
- Smooth Map : 0.11 Smooth Map : 0.12
- Layer Map : 0.09 Layer Map : 0.09
- Shadow Map : 0.14 Shadow Map : 0.14
- TOTAL : 1.04 TOTAL : 1.07
-
-
- Note that the programs uses integer maths throughout, with the exception of
- the seed value and the timer recordings. Since I don't know how much AMOS
- itself uses floating point maths behind the scenes, I can only assume that,
- since before I fitted the co-pro the times were virtually identical, the
- inclusion of a co-pro makes no difference to the program speed.
- The slight difference between AMOS 1.36 and AMOS Pro 1.12 is not a surprise,
- since I have found that, on the whole, AMOS Pro is slightly slower than AMOS,
- even if some commands are faster.
-
-
- To do another map, click the mouse once the timings are displayed.
- To quit, use the Ctrl-C combination.
-
-
-
- The results obtained from this program are a bit rough, since the routines do
- not buffer the map data in any way. Thus, what you see on screen is what the
- program uses as data. Since the main screen is 32 colour, this means there
- are effectively only 31 different heights available (since the background
- colour is not used in the maps). This makes for rather grainy maps, especially
- when adding the random deviation. Ideally I would use a 16 bit/pixel buffer,
- allowing 65000+ different levels, and then quantise the results down for
- display, with options for showing different contour levels.
-
- Eventually I hope to do this, and also add a rudimentary 3D output, probably
- isometric since my perspective 3D is somewhat pathetic, and the Voodoo 3D
- extension is not flexible enough (I know, I've tried using it for this sort of
- work, and it just doesn't deliver the goods).
- If only someone would write a decent 3D extension that provided a complete
- set of commands for 3D work, I'd get it as soon as it was released.
-
-
- Well, that about wraps it up for this readme file. I'd just like to thank the
- producer, the script writers and the director, but most of all you, for being
- there.
-
- This has been a readme file, you've been the audience. Goodnight.

-
- PC/Mac enthusiasts should stop reading now, turn away, exit this readme. Under
- no circumstances should you read on. Your primitive humour programming may
- well cause a General Protection Fault in your cerebral cortex should it come
- into contact with the humour contained below (assuming you understand it in
- the first place......)
-
- Amiga fans may of course proceed, your sense of humour is well developed
- enough to appreciate the remainder of the readme file.
-
-
-
- In order to fund the development of this readme file, I have had to resort to
- allowing advertisements to be placed. I'm truly sorry about this, but I had
- no option.

- If your memory leaks, why not try the all new Microsoft(TM) Windows(TM) sponge.
- YES! with just one application the Windows(TM) sponge will soak up all your
- leaky memory, and as a bonus will also mop up any other memory in your
- machine, leaving it competely free of emptiness.
-
- Buy a Microsoft(TM) Windows(TM) memory sponge today, and watch your computer
- choke...
-
- Also available for Macintosh(TM), under the brand name Apple(TM) System7.
-
-
-
- Does the thought of doing more than one thing at a time fill you with dread?
- Does the concept of working one multiple tasks simultaneously shake you to
- the core?
-
- NEVER MIND!!!! We've just the product for YOU!
-
- Buy Microsoft(TM) Windows(TM) right now and say goodbye to all that
- multitaskingefficientkernelslickinterfacenostupidfilenamerestrictiondraggable
- screenfastwindowsandmenus stuff you have grown to hate on greater machines.
-
- Features of Windows(TM):
-
- 1. Everything, and we mean EVERYTHING! is a trademark(TM) of Microsoft(TM),
- so your user manuals are twice as thick as any other in order to fit all the
- (TM)s in.
-
- 2. Only requires half as much disk space as the next version of Windows(TM).
-
- 3. Comes complete with a free! memory sponge, for all those annoying bits and
- bytes left running around freely.
-
- 4. You'll never have to buy any other software after Windows(TM), since you
- won't have enough drive space/memory/processor cycles left to run it anyway.
-
- 5. Comes complete with a stylish carry case *
-
- 6. Hand delivered by the ever so lovely Gates #
-
-
- * When installed on portable PCs
-
- # Unfortunately, we mean Bill Gates, as opposed to Gates McFadden....sigh
