- WA-TOR FOR WINDOWS
- ------
- Copyright (C) 1993, WARREN L. KOVACH
-
- Welcome to Wa-Tor, the sharks and fish game for Microsoft
- Windows. This program allows you to create your own world,
- populated with tasty fish and hungry sharks, and watch how the
- population changes through time.
-
- You can change parameters that determine how often the sharks and
- fish breed and how soon the sharks will starve if they can't eat
- a fish. If you get the settings right, the populations will live
- for a long time. Get them wrong, however, and the sharks might
- eat up all the fish, then starve to death. They might also all
- die off before finding any fish to feed on.
-
- It is fun to cheer on the sharks and fish as they battle it out,
- but this game is also a simulation of some ideas from population
- ecology, although it is a very simplistic model.
-
- The idea for this game comes from A.K. Dewdney's "Computer
- Recreations" column in the December 1984 issue of Scientific
- American.
-
- INSTALLATION
-
- The Wa-Tor program consists of two files, WATORW.EXE and
- WATORW.HLP. To install Wa-Tor, simply copy these two files onto
- your hard disk in any directory you desire. You can then create
- an icon for it in the Program Manager (PM) by either using the
- "File/New" option in PM, or by dragging the file from the File
- Manager directly to a PM group.
-
- STARTING WA-TOR
-
- When you first start Wa-Tor, you will see the blank game board
- and the population graph. You can first change the initial
- parameters through the Options menu, then start or stop the
- simulation through the Game menu. You can view other types of
- graphs through the Graphs menu.
-
- The game board can be cleared and a new game started by choosing
- "New" from the Game menu. Changes made to the parameters in the
- middle of a run take effect immediately.
-
- GAME BOARD
-
- Wa-Tor is a toroidal (doughnut-shaped) planet completely covered
- by an ocean. The game board shows a map of the planet flattened
- out into a square. If a fish or shark moves off one edge of the
- map, it will reappear on the other side.
-
- At the start of the game, fish and sharks are placed randomly
- around the board. You control how many are there at the start
- through the options menu. When the game starts, each fish and
- shark moves once during a chronon (time unit). Fish move onto
- the next adjacent space, chosen randomly. Sharks will first look
- around to see if a fish is within snapping distance; if not it
- too will move onto an unoccupied space.
-
- After all fish and sharks have moved once, the scoreboard will be
- updated to show the current population. The movements for the
- next chronon will then begin.
-
- Wa-Tor has a full on-line help system that gives more details
- about using the menuing system. There is also information about
- the different graph types and a brief introduction to population
- ecology.
-
- COMMENTS, COMPLAINTS, COMPLIMENTS AND BUGS
- These should be addressed to me at the address below. There are
- numerous improvements that could be made in this game, both in
- the presentation and in the actual mechanics and assumptions.
- For instance, adding a requirement for sexual reproduction could
- have interesting results in the population dynamics. If you have
- any suggestions please let me know. Thank you!
-
- REGISTRATION
-
- Wa-Tor is a shareware game. This means that you can freely copy
- it and give it to friends and colleagues. A charge may be made
