Bitcoin Forum

There are some computer games using crypto-currencies, like Cryptokingdom, Augur and so on.  Huntercoin is a game on blockchain launched in 2014 based on bitcoin source code. Cutting edge of the Huntercoin is human mining. In this introduction, I will introduce Monopoly like game based on Nxt 1.3.5 codebase with smart contract named FSM(Final State Machine),which is new design of AT(Automated Machine).

   Nearly all coins will be distributed by FSM , after players jump to the location of the coins in next block, they will share the coins. There are lands in the game too, so players can buy lands(Asset) to build hotel, restaurants, healthy club and weapon factory, which can be traded in asset market in the game also.

source code: github.com/btc2nxt/FSM

any suggestions are appreciated.

FSM(Finite State Machine) is new design of AT(Automated Machine). Two years past, FSM were still in the code and didn't improve. That is why i want to develop a game or a use case to push FSM to real world or  solve some problem of businesses. When i have been coding , i found many bugs that FSM need to improve.
Last week, i reached the first milestone which succeeded in aridropping coins, distributing dividend to asset holders.
Because i am not good at UI design, all tests are on http and offline. Actually I use Nxt1.3.5 NRS, and sometime the 1.3.5 UI too.

1. set nxt-default.properties file
nxt.apiServerEnforcePOST=false
nxt.isOffline=true

2. pre-distribute the coordinator(x,y)

variables means: will start run at height 12. After sleep 10 blocks, will run again at height 22.

account id of predistributeFSM  is 1, which is hardcoded in the source.
This FSM  will generate 5 coordinators for Airdrop FSM to delivery coins to the collectors.
http api: getPredistributeCoordinates  can show them.

3. Airdrop FSM
http://127.0.0.1:9776/nxt?requestType=createATProgram&secretPhrase=btc2nxtTest1&atVersion=1&name=airdropFSM&description=test&runType=SYSTEM_AT&machineCode=1e000000001f35000300000000070000000003000000070000000003000000374903110000000000000001000000261100000035000100000000020f00000000000000060f0000000400000002100000000000000006100000000500000002140000000300000026140000003448031100000014000000375203120000000f0000001000000005140000001b12000000dc021300000002000000091300000012000000010a0000000000000000000000040a0000003447030f000000100000003302041300000005120000001e12000000e42a2114000000030000000f1a6700000028&machineData=00000000000000000100000000000000005cb2ec220000000500000000000000000000000100000000000000070000000000000000000000&variables=01000000050000000a000000001500000070000000&feeNQT=200000000000&deadline=1440

account of Airdrop FSM is 2, which's balance is zero, so must send many coins to it.

4. Be a collector

landId=5..8 are hotels
landId=9..12 are restaurants

After issue assets, lands of town bind to assets.

7.Be a workder

the asset id must be the id of land's asset.

The room need 5 Builds to finish.

9. shareRedeemFSM

shareRedeemFSM will auto send shares to workers, depends on workers' works. Because the asset is not create by shareRedeemFSM, we have to transfer asset to it, which has account id 3.

hareRedeemFSM will run at height 16, and continue to run in 10 blocks.

A player's CollectPower will restore to 100 after check in, and has to sleep 4 hours. All amountNQT goes to dividendFSM's account, which id is 4.

Cool stuff as a hobby project, don't see how you'd monetize this though.

When FSM runs fine, many use cases can be implemented on it ;D.

Momopoly is the game of my childhood. I would try to play  :)

But not me. I played this game in my childhood. But I usually always lost. I did not like this game  :(

I also always lost when I played with my friends. The very process of the game was very interesting and exciting. We even played a monopoly for a few days. I guess I just was not lucky with this game.

TestNet is OK.

Are you still developing this game?
