This commit addresses multiple issues with `Variant`s that point to an `Object` which is later released, when it's tried to be accessed again. Formerly, **while running on the debugger the system would check if the instance id was still valid** to print warnings or return special values. Some cases weren't being warned about whatsoever. Also, a newly allocated `Object` could happen to be allocated at the same memory address of an old one, making cases of use hard to find and having **`Variant`s pointing to the old one magically reassigned to the new**. This commit makes the engine realize all these situations **under debugging** so you can detect and fix them. Running without a debugger attached will still behave as it always did. Also the warning messages have been extended and made clearer. All that said, in the name of performance there's still one possible case of undefined behavior: in multithreaded scripts there would be a race condition between a thread freeing an `Object` and another one trying to operate on it. The latter may not realize the `Object` has been freed soon enough. But that's a case of bad scripting that was never supported anyway.
Godot Engine
Homepage: https://godotengine.org
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 in one click to a number of platforms, including the major desktop platforms (Linux, Mac OSX, Windows) as well as mobile (Android, iOS) and web-based (HTML5) platforms.
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 Software Freedom Conservancy 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 homepage.
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.
To get in touch with the developers, the best way is to join the #godotengine IRC channel on Freenode.
To get started contributing to the project, see the contributing guide.
Documentation and demos
The official documentation is hosted on ReadTheDocs. It is maintained by the Godot community in its own GitHub repository.
The class reference is also accessible from within the engine.
The official demos are maintained in their own GitHub repository as well.
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 info.
