The game of Hamurabi with a new coat

[Henko]

The internal mechanisms are based on my earlier text version "old school Hamurabi", with a few extentions.

Very nice! The game is much easier to play with the on-screen keyboard. So far I have not been impeached!

I have to report a wrong calculation inthe function DEF DECISIONS():

Code: Select all

def decisions()
field "inp" text "  How many bushels food for the "&(.C+.V)&" people?"
.Et=numpad(0,.SQ) ! .SQ=max(1,.SQ-.Et)
field ("stock") text "        "&.SQ
put_msg(.Et&" bushels food for the population")
field "inp" text "How many bushels as seed for new crops?"
.Zt=numpad(0,.SQ) ! .SQ=max(1,.SQ-.Zt)
field ("stock") text "        "&.SQ
put_msg(.Zt&" bushels used as seed for new crop")
.k=max(10,int(.6*.k+.4*(rnd(61))))
field "inp" text "How many bushels for buying land at "&.k&"/acre?"
Kt=numpad(0,.SQ)
if Kt>0 then
  .SQ=max(1,.SQ-Kt) ! dS=int(Kt/.k) ! .S+=dS
  put_msg(dS&" acres of land bought for "&Kt&" bushels")
  field ("stock") text "        "&.SQ
  end if
ks=.k-2-rnd(7)
field "inp" text "How many acres to sell at "&ks&" bushels/acre?"
dS=numpad(0,.S)
if dS>0 then

'y'
  dSQ=int(dS*.k) !.SQ=max(1,.SQ-dSQ) ! .S+=dS
''

  put_msg(dS&" acres of land sold for "&dSQ&" bushels")
  field ("stock") text "        "&.SQ
  end if
field "inp" text " Touch next period button to continue"
end def

In the isolated line, two signs, a plus and a minus must be changed as follows:

dSQ=int(dS*.k) !.SQ=max(1,.SQ+dSQ) ! .S-=dS

I will also edit the code in the first post

Nice "coat" for that old interesting game

Nice "coat" for that old interesting game :!:

Thanks. I merely grabbed three already existing utilities together ;)

[GeorgeMcGinn]

I like your version of Hammurabi game. It has some of the features that I'm putting into mine, plus I'm adding a lot more decision making processes.

However, in the three original source codes that I provided, plus in the one that I am currently coding, the original authors decided that you should either buy or sell land first, before deciding on how much you have to feed and plant for the next season.

I ran into a situation playing your game where I did not have enough grain to feed people, but if I was able to sell some land first I would have had enough grain not only feed my population but also to plant enough for the next season.

I think the original authors put those choices first so that you could maintain your population, i.e. not starving them, and allowed you to rebuild the amount of the land that you need for your population, which is more than 10 acres per person.

Another way to set up the order in which things are done would be to allow the selling of land first and then feeding the population, planting the harvest, and then if you have anything left over you can then purchase land.

I hope to have my version or most of it ready in a month, and it's going to be one hell of a game to play. I will be taking Hammurabi to new levels of decision-making and complexity, rivaling any strategy game on the market today.

I really like the numeric keypad that you have put in the game, and I may use a version of it, but I think also rbytes wrote a numeric keypad program as well. I plan to not scroll but put each year in a box with a button so you can look back and forth on previous years. Also my GUI Will have a continuous running total of all the numbers needed to make decisions. But we'll see how far I get with the graphics on the next version.

Well done on the game I like it, and if you're going to come up with a new version I can't wait.

George

However, in the three original source codes that I provided, plus in the one that I am currently coding, the original authors decided that you should either buy or sell land first, before deciding on how much you have to feed and plant for the next season.

Yes, i see the logic of that. I will change the order of things accordingly, although i do not persé strive to a one-to-one relationship with the original game.
I will post the next (and final) of my version, when i have implemented a graphics representation at the bottom of the screen.

You make me/us very curious about your top of the top strategy game. One month ehh..., i'll put a note in my agenda .

[Henko]

If you are interested in management-like games, i designed and coded an "oil company simulation" game in april/may 2013.

The game and the manual can be find in the program section:
viewtopic.php?f=20&t=115

Perhaps, after 6 years, i will give that game also a new "coat" and add functionality to it (transportation of crude oil and gasoline with a oil tanker fleet)

The introduction of the manual follows:


Oil company simulation game (version 2)

This simulation consists of an infinite number of rounds (periods) in which one must try to make an oil company as succesfull as possible. The game ends with bankruptcy if you make a mess of it or by simply hitting the cross in the right upper side of the window. A simulation can be saved and resumed afterwards. The program code complies with Smart Basic version 2.0.1. It does not run under previous versions of Smart Basic.

Each period (say a quarter of a year) has 3 phases:
- an exploration & acquisition phase, in which to find oil wells and acquire concessions.
- a production phase, in which to decide about production, storage and sales.
- an investment phase, in which to decide about production and storage capacities.

There are two products: crude oil from the wells and (refined) gasoline.
There are four types of production means:
- exploitation of oil wells (production of crude oil)
- storage of crude oil (tank park)
- refinery of crude oil into gasoline (plant)
- storage of gasoline (tank park)

Selling prices for each of the two products vary with a trend factor, a season factor and some arbitrary fluctuations.
The minimum price for crude oil is 60 dollars per unit, maximum is 200.
The minimum price for gasoline is 200 dollars per unit, maximum is 500.

Oil wells are scattered randomly in a 45x45 lots area. Each lot may be concessioned by you or by competitors (if there are any).
Oil fields vary in size from one single lot to large 6x6 lots, distributed as follows:
6x6 lots: 2 fields
5x5 lots: 2 fields
4x4 lots: 3 fields
3x3 lots: 5 fields
2x2 lots: 10 fields
1x1 lot : 30 fields
Large lots have more oil in the centre parts then at the outskirts.
Oil fields may (partly) overlap, other shapes than square fields are possible.
The probability that an arbitrary lot contains oil is less than 14% (less than 1 out of 7).
Oil wells are depleted as the oil is taken out by the company.

[GeorgeMcGinn]

I loaded the game, but I'm fighting a ton of syntax errors.

I first fixed all the comments that were put after a label (action: ' comment was here) and one after a THEN where the next line was a multi-statement line.

Now I'm getting Syntax errors on the BUTTON statements. I've been replacing title with text, and now I think the + and - signs in the button name and the text are causing the errors. Here is an example:

button "+exp" text "+" at 210,60  size 40,40

I am assuming that the +/- signs are important as far as telling me I'm either adding or subtracting something in the game.

I will do a walk through on the code to make sure those symbols are not used to build mathematical formula, or concatenated to the front of a string and converted using the VAL statement.

So far, I've yet to strike oil, but I'll keep drilling down the code unless you have an updated version!

Cheers, George.
