1. Make handling of user tokens atomic: Loads started with the external-facing API used to perform a two-step setup of the user token. Between both, the mutex was unlocked without its reference count having been increased. A non-user-initiated load could therefore destroy the load task when it unreferenced the token. Those stages now happen atomically so in the one hand, the described race condition can't happen so the load task life insurance doesn't have a gap anymore and, on the other hand, the ugliness that the call to load could return `ERR_BUSY` if happening while other thread was between both steps is gone. The code has been refactored so the user token concerns are still outside the inner load start function, which is agnostic to that for a cleaner implementation. 2. Clear ambiguity between load operations running on `WorkerThreadPool`: The two cases are: single-loaded thread directly started by a user pool task and a load started by the system as part of a multi-threaded load. Since ensuring all the code dealing with this distinction would make it very complex, and error-prone, a different measure is applied instead: just take one of the cases out of the dicotomy. We now ensure every load happening on a pool thread has been initiated by the system. The way of achieving that is that a single-threaded user-started load initiated from a pool thread, is run as another task. |

Godot Engine
2D and 3D cross-platform game engine
Godot Engine is a feature-packed, cross-platform game engine to create 2D and 3D games from a unified interface. It provides a comprehensive set of common tools, so that users can focus on making games without having to reinvent the wheel. Games can be exported with one click to a number of platforms, including the major desktop platforms (Linux, macOS, Windows), mobile platforms (Android, iOS), as well as Web-based platforms and consoles.
Free, open source and community-driven
Godot is completely free and open source under the very permissive MIT license. No strings attached, no royalties, nothing. The users' games are theirs, down to the last line of engine code. Godot's development is fully independent and community-driven, empowering users to help shape their engine to match their expectations. It is supported by the Godot Foundation not-for-profit.
Before being open sourced in February 2014, Godot had been developed by Juan Linietsky and Ariel Manzur (both still maintaining the project) for several years as an in-house engine, used to publish several work-for-hire titles.
Getting the engine
Binary downloads
Official binaries for the Godot editor and the export templates can be found on the Godot website.
Compiling from source
See the official docs for compilation instructions for every supported platform.
Community and contributing
Godot is not only an engine but an ever-growing community of users and engine developers. The main community channels are listed on the homepage.
The best way to get in touch with the core engine developers is to join the Godot Contributors Chat.
To get started contributing to the project, see the contributing guide. This document also includes guidelines for reporting bugs.
Documentation and demos
The official documentation is hosted on Read the Docs. It is maintained by the Godot community in its own GitHub repository.
The class reference is also accessible from the Godot editor.
We also maintain official demos in their own GitHub repository as well as a list of awesome Godot community resources.
There are also a number of other learning resources provided by the community, such as text and video tutorials, demos, etc. Consult the community channels for more information.
