OpenGOO and Using Inkscape or Blender for Editing Maps/Levels

Building bridges in OpenGOO

You may remember that in the first Humble Indie Bundle, World of Goo was not open-sourced. Well, there is an active open source clone called OpenGOO being developed. It uses OpenGL, Box2D and is GPLv3-licensed.

Basic layers of level creation in OpenGOO

There are instructions available for creating levels. Inkscape is used for that purpose, just like in Shotgun Debugger! A method I would love to see being widely used in games that allow for user-generated content in general.

Speaking of not-re-inventing-wheels: the team behind SuperTuxKart recently posted an article about using Blender as a level editor, rather than writing and maintaining an own content creation tool, which I highly recommend to all developers of 3D games with 'traditional' engines.

Open Source in Humble Indie Bundle #3: Haaf's Game Engine (HGE)

HGE's Particle Editor

The proprietary games sale Humble Indie Bundle has a tradition of including open source engine releases.

In all of the other humble bundles there has always been at least one game that opened its source (in #2 it was revenge of the titans. in #1 it was penumbra, lugaru, aquaria and gish).

- Fer C.

Bundle #3 is soon over and the *nix port of the Windows-only zlib-licensed engine HGE has been now released as open source as well. It is the engine used by Hammerfight from the Bundle. Visit the pages: hge, hge-unix.

The non-free BASS audio library was replaced with OpenAL.

The hge-unix readme states "10 I don't know anything about the Windows version of HGE.", which might mean that developers have to juggle two engine versions and audio libraries if they want to support the three main platforms. Or hge-unix needs to be ported back to windows systems.

You can read more about the port in the blog post HGE comes to Mac and Linux by Ryan Gordon aka icculus. Or perhaps watch his talk about Linux/open source gaming (again?).
