Unity Technologies has stepped up its commitment to democratising game development by making key components of its ubiquitous engine open source.
At present, that applies to the Unity Test Tools and the engine's new graphical user interface system, which was demonstrated in the opening keynote of Unite 2014. The features will be available under the MIT/X11 license, giving users the freedom to "control, customise and extend" their functionality.
The source code for the components will be hosted on BitBucket, and Unity has prepared a guide for any interested open source contributors. The source for the Unity Test Tools is already available, with the GUI to follow.
"Beyond that, we don't have a concrete plan, but we have a lot of things in the pipeline," the company said in a statement. "These components will all be isolated from Unity in such a way that you can modify them and use your own modified version with the official public Unity release.
"Although Unity Technologies has been active in the open-source community for quite some time, this is the first time we'll be opening the source to components of Unity itself.
"We're excited to see what you do with it."
