tasks

1. categorize classifiers -> DONE

• card modifiers (priority 0)
• rule modifiers (priority 1) -> changing rules
• score modifiers (priority 2) -> modifying scores
  • card scores
  • hand scores

2. data structure -> how are we storing the game state / variables
3. classifier ordering -> DONE

tasks

• from AS IS to modifier support

legends

• modifiers change card behaviour
• classifiers change rules of the system

notes

classifiers:

• every face card (jack, queen, king) gives 30 extra points
• face cards count as spades
• spades give extra 10 points
• hearts and diamonds count as the same suit, spades and clubs count as the same suit
• you can have a straight/flush with only 4 cards
• you can have gaps of 1 in your straights
• you score 20 extra points if you play fewer than 4 cards
• for every time you played this poker hand (pair, twoPair, etc.) get +2 chips
  • first time you play a pair you get +2, second time +4, third time +6, etc.
• all played cards count in scoring even though they are invalid
• make your own classifier

there are different groups of classifiers!

• e.g. by ranking or by when the action appears

classifiers = [class1, class2, class3] -> user can pick the order You can have multiple classifiers, for ex:

• hearts and diamonds count as the same suit, spades and clubs count as the same suit
• you can have a straight/flush with only 4 cards
• you can have gaps of 1 in your straights H2 D3 D5 H7 is a straight flush

ideas:

• e.g. add flush score to any card
• have a bucket that keeps track of the score
• composition (base properties and allow overwriting)
• look into design patterns, e.g. middleware - "plug"
• standardize inputs and outputs to share tests
• testing factory
• oop vs functional vs mix vs procedural

types of classifiers

• card modifiers (priority 0)
• rule modifiers (priority 1) -> changing rules
• score modifiers (priority 2) -> modifying scores
  • card scores
  • hand scores

what if multiple classifiers work in tandem

// with card modifiers
[
  // card
  "face cards count as spades",  // [8 club,null,10 spade,J spade,Q spade]
  "hearts and diamonds count as the same suit, spades and clubs count as the same suit" // [8 cs,null,10 cs,J cs,Q cs]
  // rule
  "you can have gaps of 1 in your straights", // [8 cs,null,10 cs,J cs,Q cs]
  "you can have a straight/flush with only 4 cards", // flush = true
] // returns straight flush

// combined
[
  "you can have gaps of 1 in your straights", // [8 club,JOKER,10 spade,J heart,Q diamond]
  "you can have a straight/flush with only 4 cards", // flush = true
  "face cards count as spades",  // [8 club,JOKER,10 spade,J spade,Q spade]
  "hearts and diamonds count as the same suit, spades and clubs count as the same suit" // [8 cs,JOKER,10 cs,J cs,Q cs]
] // returns straight flush

// last two swapped (combined)
[
  "you can have gaps of 1 in your straights", // [8 club,JOKER,10 spade,J heart,Q diamond]
  "you can have a straight/flush with only 4 cards", // flush = true
  "hearts and diamonds count as the same suit, spades and clubs count as the same suit" // [8 cs,JOKER,10 cs,J hd,Q hd]
  "face cards count as spades",  // [8 cs,JOKER,10 cs,J cs,Q cs]
] // returns straight flush

hand: [8 club,null,10 spade,J heart,Q diamond] -> straight flush

categorization

classifiers (these are run after the cards are already played):

• score: every face card (jack, queen, king) gives 30 extra points
• rule : face cards count as spades
• score: spades give extra 10 points
• rule : hearts and diamonds count as the same suit, spades and clubs count as the same suit
• rule : you can have a straight/flush with only 4 cards
• rule : you can have gaps of 1 in your straights
• score: you score 20 extra points if you play fewer than 4 cards
• score: for every time you played this poker hand (pair, twoPair, etc.) get +2 points
  • first time you play a pair you get +2, second time +4, third time +6, etc.
• rule : all played cards count in scoring even though they are (not part of a hand)
• xxxx : make your own classifier

there are different groups of classifiers!

• e.g. by ranking or by when the action appears

classifier groups

at this point, we already have all the card played, and we are in the calculation phase

• before you start iterating through the hand (preprocess)
  • validation
  • apply rule classifiers
• CALCULATION
• after (postprocess)
  • apply score classifiers

steps

1. play cards
2. calculate with classifiers
3. return score

we have poker functions (base rules) classifiers change the poker functions
