Mahjong-seatings-rs-bundlers

Small wrapper around mahjong-seatings-rust to compile it to wasm, bundlers version.

Usage

• Install package: npm install mahjong-seatings-rs-bundlers
• Setup your webpack or other bundler to use wasm files
  • For webpack, add the following to webpack config:
  • experiments: { asyncWebAssembly: true }
• Invoke function as follows:

import {
  make_seating_shuffled,
  make_seating_interval,
  make_seating_swiss,
} from "mahjong-seatings-rs-bundlers";

console.log(
  "Shuffled seating",
  make_seating_shuffled({
    playersMap: {
      "1": 1500,
      "2": 1500,
      "3": 1500,
      "4": 1500,
      "5": 1500,
      "6": 1500,
      "7": 1500,
      "8": 1500,
    },
    previousSeatings: [
      [1, 2, 3, 4],
      [5, 6, 7, 8],
    ],
    groupsCount: 1,
    randFactor: 1234455,
    windShuffle: "random", // other options: 'balanced'
  }),
);

console.log(
  "Interval seating",
  make_seating_interval({
    playersMap: {
      "1": 1510,
      "2": 1508,
      "3": 1506,
      "4": 1504,
      "5": 1496,
      "6": 1494,
      "7": 1492,
      "8": 1490,
    },
    previousSeatings: [
      [1, 2, 3, 4],
      [5, 6, 7, 8],
    ],
    step: 2,
    randFactor: 1234455,
    windShuffle: "random", // other options: 'balanced'
  }),
);

console.log(
  "Swiss seating",
  make_seating_swiss({
    playersMap: {
      "1": 1510,
      "2": 1508,
      "3": 1506,
      "4": 1504,
      "5": 1496,
      "6": 1494,
      "7": 1492,
      "8": 1490,
    },
    previousSeatings: [
      [1, 2, 3, 4],
      [5, 6, 7, 8],
    ],
    randFactor: 1234455,
    windShuffle: "random", // other options: 'balanced'
  }),
);

Note that returned lists contain player ids and their rating. First four elements are first table, next four are second table, etc.

In case you already have the prepared seating and just want to randomize seatings by wind, you can use update_wind_placing_only function:

import { update_wind_placing_only } from "mahjong-seatings-rs-bundlers";

console.log(
  "Updated wind placing",
  update_wind_placing_only({
    playersMap: {
      "1": 1510,
      "2": 1508,
      "3": 1506,
      "4": 1504,
      "5": 1496,
      "6": 1494,
      "7": 1492,
      "8": 1490,
    },
    previousSeatings: [
      [1, 2, 3, 4],
      [5, 6, 7, 8],
    ],
    randFactor: 1234455,
    windShuffle: "random", // other options: 'balanced', 'prescripted'
  }),
);

Note that windShuffle: 'prescripted' option just returns input array as is, considering it being already shuffled manually.
