Turbulenz

Turbulenz is one of the few open source game engines that have been actually used for production games.

Whilst most HTML 5 game engines are more of an experiment on the developers' part of getting around the new features of HTML 5 and testing out products for future commercial projects, Turbulenz actually went backwards in this process.

The Turbulenz team created and released lots of great HTML5, browser-based games and then decided to open source this great tool so other developers could take advantage of their experience.

The engine itself uses lots of JavaScript, C++ and TypeScript, and needs a Python compiler to get the development process started.

Turbulenz comes with a very extensive documentation and useful tutorials to help programmers get started with their first games.

What is new in this release:

• Fixed an issue in draw2D where sprites were incorrectly scaled around the origin.
• Added debug assertion for draw2D when npot textures are used with mipmaps not supported.
• Fixed missing copyright comments.
• Added viewBox transforms to svg implementation.
• Fixed the handling of gamesession create to treat 404s as if services are unavailable.
• Request handler now retries if 504 responses are encountered instead of failing immediately.
• Improved handling of non-JSON responses to API requests.
• Added support for tar files to deps.yaml and build process.
• General improvements to the soundDevice for stability and the process of incorrectly loaded files.
• Performance improvements to asset loading, especially for large files.
• Work-around fixes to support IE11 for incomplete WebGL specification.
• Added subtitles sample.
• Added FontManager support for multiple pages.
• Modified FontManager to use tri-strip instead of fan for single characters. Temporary fix for IE11.
• PhysicsManager optimizations.
• Update protolib library (version 0.2.1).
