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

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.

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

The room need 5 Builds to finish.

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.
