Casino

Playing around with applications to try to create a blackjack game.

Things of note:

• GameManager.Start - kicks off the main logic
  • start table and build deck + shuffle
  • start table state machine to handle game logic
  • simulate four players joining
    • start up a player gen server with a reference to the table_id
    • hack to give players each their own info
    • Fetch the player info
    • Notify the state machine that players have joined
  • Increase the uuid for the id counter for the next game
• GameManager.Table.StateMachine - handles the game state
  • player_joined
  • player_left
  • switches from waiting -> playing state
  • allows to fetch current_player
  • allows to switch to the next_player
• GameManager.Player.Player - basic player
  • allows to get_info
  • can add_player_info about a specific player (name, etc)
  • can call hit to fetch a new card
    • This will return your current deck, newest card, and total handle count
  • can call stay to change the table's state_machine to the next player
• TableManager.Table.Card - a simple card in a deck of cards
  • has a value function to return the value of a given card
  • note: returns [1, 11] for ace
• TableManager.Table.DeckBuilder - builds a deck of cards
• TableManager.Table.Hand - representation of a hand for a specific game
  • has a count function given a hand to compute the value for a given hand
  • You can pass a second argument to count to count ace as high
• TableManager.Table.Dealer - deals the cards in a deck
  • the dealer will shuffle the cards after starting up
  • hit will return the first card from the deck
  • if you ask nicely with show_deck the dealer will print the results of the deck currently
