Squish

This repo contains the game library used by homegames-core and homegames-web to efficiently serialize & deserialize game data.

squish/unsquish

This is just serialization/deserialization. Conceptually similar to protobufs, squish contains schema definitions shared by the server and client that lets us transmit game data as efficiently as possible.

const { squish, unsquish, Colors, GameNode, Shapes, ShapeUtils } = require('squish-1006');
const node = new GameNode.Shape({
  shapeType: Shapes.POLYGON,
  fill: Colors.COLORS.RED,
  coordinates2d: ShapeUtils.rectangle(20, 20, 10, 10)
});

const squished = squish(node);

Game

The Game class is a base class that allows external components (eg. a Squisher) to listen to state updates. All games in Homegames extend the Game class.

Versioning

Homegames core & web use multiple versions of squish. This allows games using older versions of squish to remain compatible with newer versions of Homegames.
