Isogenic Game Engine

HTML5 2D and isometric scenegraph-based game engine written entirely in JavaScript.

25th March 2023

The original engine was written over 12 years ago, and it is a testament to that work that it is still by far the most feature-rich browser-based game engine available today. There is still NO OTHER engine that supports realtime multiplayer streaming out of the box written purely in JavaScript in a 2d and isometric rendering engine.

With all that said, it's 2023 and back in 2011, ES classes, ES modules, TypeScript, webpack etc did not exist. As such, language functionality such as classes were custom-created to facilitate an inheritance-style codebase. This was great, as was the magic of using ES classes years before they even existed, but now we have native functionality in JavaScript, a rewrite of the engine needs to happen to make use of that new functionality. The changes to the engine to support native functionality is in the branch es6-typescript that has largely completed the work of converting the engine to use native ES6 classes and TypeScript for all engine features. It will soon be merged into the master branch and will be considered the production version.

Minor changes exist as well as some breaking changes (such as the removal of ClientConfig and ServerConfig files) that were ultimately made to increase functionality or update anachronistic coding patterns to more modern expectations.

The major changes are:

The built-in compiler is no longer required since import now exists in browsers natively, so it is no longer a requirement to compile using the engine's compiler to get a runnable project / game. You should code with ES modules import and export, not CommonJS require and module.exports.

The node.js server-side executable system that ran IGE on your server for multiplayer support has been removed as the isomorphic JavaScript output runs natively in Node.js - again due to the support for ES modules, ES classes and there is no need to "package" projects / games anymore! :)

The ClientConfig.js and ServerConfig.js are no longer required and can be removed everywhere. The engine simply uses ES module imports and exports now, directly in the files that need them.

Many of the examples in the examples folder have been converted to TypeScript and ES modules. You can tell which ones can be run because there will be an index.ts rather than only an index.js file.

If you are starting a new project, you should use the es6-typescript branch in order to remain compatible with changes being made there rather than using the master branch.
