# 🃏 for Mina Bootcamp

My current problems about MINA:

1. Texas Hold'em is a long game. It's better to use multiple files to modularize the process.

   1. How to call other snapps on chain. Is there a smart contract list that we can use as tool?

   2. User and server should run different snapps can communicate with each other.

2. What should stay on-chain. How's the chain only 22KB?

3. Need more docs on `State`. It seems can only be read once?

4. How to send message to a specific account? I did Hash(`AccountPublicKey+Message`), but don't know where to post this message. Would be too many things on the chain if we do this every time dealing a card.

## Dev process

### Day 1: Find a game to make

- Considered Civ6, Quarto, Texas Hold'em.

- Decided to write a Texas Hold'em.

- Some UI for test. (didn't reach there after 3 days) I think [wallaceturner/crypto-poker](https://github.com/wallaceturner/crypto-poker) is a good. But too complicated to use. It's written with [AureliaJS](https://aurelia.io/)

- Read again[mitschabaude/snarkyjs-sudoku](https://github.com/mitschabaude/snarkyjs-sudoku)

- Tried to implement an AI: [wenkesj/holdem](https://github.com/wenkesj/holdem)

### Day 2: UI & Poker Engine

- Wrote a simple UI myself to show cards from `card_code`

- Tried to implement some extensions

  - [rundef/node-poker-odds-calculator](https://github.com/rundef/node-poker-odds-calculator)

  - [ktseng/holdem_calc](https://github.com/ktseng/holdem_calc)

- Looked for Poker engine

  - [goldfire/pokersolver](https://github.com/goldfire/pokersolver)

  - Didn't use[mjhbell/node-poker](https://github.com/mjhbell/node-poker). Out of date, no NPM.

  - Didn't use [brunoscopelliti/poker-holdem-engine](https://github.com/brunoscopelliti/poker-holdem-engine), because it's an online API and seems everyone can shuffle the deck.

- Wrote a part of my poker engine (class `OldDeck`) to encode/decode card deck shuffle deal cards. Other engines don't have a way to encode/decode.

  > encode refers is a function, which takes the card order of the deck and gives a `BigInt`, decode is its inverse.

  > It's for saving the deck so to continue later.

  > On day 3 I found it not needed: just draw a random card from the deck and deal it.

- Wrote a new deck with a function to show deck like the table below

  | Shown | Meaning          |

  | ----- | ---------------- |

  | "A♣"  | Ace of Spades    |

  | "Q♦"  | Queen of Hearts  |

  | "9♥"  | Nine of Diamonds |

  | "5♠"  | Five of Clubs    |

- Improve development environment (my tool)

- SnarkyJS

  - read [TicTacToe guide](https://o1labs.org/tictactoe)

  - debug `await this.gameStage.get();` can't use twice, where `gameStage` is a `State` (failed)

  - Came up with a new way to record the bookkeeping of the game. Charge all user with a `buyIn` then note it down to a `Map`.

### Day 3

- SnarkyJS

  - Tried(failed) to deal card, as aforementioned "4. How to send message to a specific account?"

  - Tried(failed) to make two snapps, one for user and one for server.

- Wanted to change the project to TicTacToe with UI and bet.

  - Started a new repo for TicTacToe and copied the code from [TicTacToe guide](https://o1labs.org/tictactoe).

  - Reevaluated that I cannot finish it either(in 2h).

- Git

  - Fixed detached head

  - Upload GitHub

  - Fix typo while writing this doc.

## feature goal

- Timer

- Show and use bets/buyIn/credits in USD.

### MINA questions

- Can I check now many MINA does user have? Or does user have XXX amount of MINA?

## Dev story

- Why do I want to shuffle ? ? ?? ?? ??

  Truly the status number will be much much fewer w/o shuffle.
