About

NOTE: This Flatpak is unofficial and not supported by Godot Engine developers. Find officially supported binaries on godotengine.org. The feature-packed, cross-platform game engine to create 2D and 3D games from a unified interface. Godot Engine provides a comprehensive set of common tools, so that you 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, macOS, Windows) as well as mobile (Android, iOS), web-based (HTML5) platforms and consoles (Switch, PS4 and Xbox One - via thirdparty publishers). Completely free and open source under the very permissive MIT license. No strings attached, no royalties, nothing. Your game is yours down to the last line of engine code. Godot's development is fully independent and community-driven, empowering you to help shape the engine to match your expectations. It is supported by the non-profit Godot Foundation. Create games with ease, using Godot's unique approach to game development: Nodes for all your needs. Godot comes with hundreds of built-in nodes that make game design a breeze. You can also create your own for custom behaviors, editors and much more. Flexible scene system. Create node compositions with support for instancing and inheritance. Visual editor with all the tools you need packed into a beautiful and uncluttered context-sensitive UI. Friendly content creation pipeline for artists, level designers, animators and everything in between. Persistent live editing where changes are not lost after stopping the game. It even works on mobile devices! Create your own custom tools with ease using the incredible tool system. Limitations of the Flatpak version: Although built with Mono 6, this Flatpak uses .NET 8 for building C# solutions in Godot projects. To (re)build a C# solution in the Godot editor, make sure that "Editor -> Editor Settings --> Mono --> Builds --> Build Tool" is set to "dotnet CLI", and not "MSBuild (Mono)", before (re)building the C# solution, otherwise Godot won't be able to find MSBuild. It should be set to "dotnet CLI" by default, but if it isn't, reset it by going to the editor settings as previously described. C#/.NET/Mono external editor support does not work out-of-the-box, though this is currently being discussed and worked on.
