We now cache the Node*<>TreeItem* mapping in the SceneTreeEditor. This allows us to make targeted updates to the Tree used to display the scene tree in the editor. Previously on almost all changes to the scene tree the editor would rebuild the entire widget, causing a large number of deallocations an allocations. We now carefully manipulate the Tree widget in-situ saving a large number of these allocations. In order to know what Nodes need to be updated we add a editor_state_changed signal to Node, this is a TOOLS_ENABLED, editor-only signal fired when changes to Node happen that are relevant to editor state. We also now make sure that when nodes are moved/renamed we don't check expensive properties that cannot contain NodePaths. This saves a lot of time when SceneTreeDock renames a node in a scene with a lot of MeshInstances. This makes renaming nodes go from ~27 seconds to ~2 seconds on large scenes. SceneTreeEditor instances will now also not do all of the potentially expensive update work if they are invisible. This behavior is turned off by default so it won't affect existing users. This change allows the editor to only update SceneTreeEditors that actually in view. In practice this means that for most changes instead of updating 6 SceneTreeEditors we only update 1 instantly, and the others only when they become visible. There is definitely more that could be done, but this is already a massive improvement. In complex scenes we see an improvement of 10x, things that used to take ~30 seconds now only take 2. This fixes #83460 I want to thank KoBeWi, TokisanGames, a-johnston, aniel080400 for their tireless testing. And AeioMuch for their testing and providing a fix for the hover issue.
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.
