These callbacks are used for marshaling by callables and generic Godot collections. C# generics don't support specialization the way C++ templates do. I knew NativeAOT could optimize away many type checks when the types are known at compile time, but I didn't trust the JIT would do as good a job, so I initially went with cached function pointers. Well, it turns out the JIT is also very good at optimizing in this scenario, so I'm changing the methods to do the conversion directly, rather than returning a function pointer for the conversion. The methods were moved to `VariantUtils`, and were renamed from `GetFromVariantCallback/GetToVariantCallback` to `ConvertTo/CreateFrom`. The new implementation looks like it goes through many `if` checks at runtime to find the right branch for the type, but in practice it works pretty much like template specialization. The JIT only generates code for the relevant branch. Together with inlining, the result is very close or the same as doing the conversion manually: ```cs godot_variant variant; int foo = variant.Int; int bar = VariantUtils.ConvertTo<int>(variant); ``` If the type is a generic Godot collection, the conversion still goes through a function pointer call. The new code happens to be much shorter as well, with the file going from 1057 lines to 407. Side note: `Variant.cs` was mistakenly created in the wrong folder, so I moved it to the `Core` folder. |

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 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.
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.
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 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.
