Which platforms are supported by Godot?

For the editor:

  • Windows
  • Mac OS X
  • X11 (Linux, *BSD)

For exporting your games:

  • Windows (and UWP)
  • Mac OS X
  • X11 (Linux, *BSD)
  • Android
  • iOS
  • Web

Both 32- and 64-bit binaries are supported where it makes sense, with 64 being the default.

Some users also report building and using Godot successfully on ARM-based systems with Linux, like the Raspberry Pi.

Additionally, there is some unofficial third-party work being done on building for some consoles. However, none of this is included in the default build scripts or export templates at this time.

For more on this, see the sections on exporting and compiling Godot yourself.

Which programming languages are supported in Godot?

The officially supported languages for Godot are GDScript, Visual Scripting, C#, and C++. See the subcategories for each language in the scripting section.

If you are just starting out with either Godot or game development in general, GDScript is the recommended language to learn and use since it is native to Godot. While scripting languages tend to be less performant than lower-level languages in the long run, for prototyping, developing Minimum Viable Products (MVPs), and focusing on Time-To-Market (TTM), GDScript will provide a fast, friendly, and capable way of developing your games.

Note that C# support is still relatively new, and as such, you may encounter some issues along the way. Our friendly and hard-working development community is always ready to tackle new problems as they arise, but since this is an open-source project, we recommend that you first do some due diligence yourself. Searching through discussions on open issues is a great way to start your troubleshooting.

As for new languages, support is possible via third parties using the GDNative / NativeScript / PluginScript facilities. (See question about plugins below.) Work is currently underway, for example, on unofficial bindings for Godot to Python and Nim.

What is GDScript and why should I use it?

GDScript is Godot’s integrated scripting language. It was built from the ground up to maximize Godot’s potential in the least amount of code, affording both novice and expert developers alike to capitalize on Godot’s strengths as fast as possible. If you’ve ever written anything in a language like Python before then you’ll feel right at home. For examples, history, and a complete overview of the power GDScript offers you, check out the GDScript scripting guide.

There are several reasons to use GDScript–especially when you are prototyping, in alpha/beta stages of your project, or are not creating the next AAA title–but the most salient reason is the overall reduction of complexity.

The original intent of creating a tightly integrated, custom scripting language for Godot was two-fold: first, it reduces the amount of time necessary to get up and running with Godot, giving developers a rapid way of exposing themselves to the engine with a focus on productivity; second, it reduces the overall burden of maintenance, attenuates the dimensionality of issues, and allows the developers of the engine to focus on squashing bugs and improving features related to the engine core–rather than spending a lot of time trying to get a small set of incremental features working across a large set of languages.

Since Godot is an open-source project, it was imperative from the start to prioritize a more integrated and seamless experience over attracting additional users by supporting more familiar programming languages–especially when supporting those more familiar languages would result in a worse experience. We understand if you would rather use another language in Godot (see list of supported options above). That being said, if you haven’t given GDScript a try, try it for three days. Just like Godot, once you see how powerful it is and rapid your development becomes, we think GDScript will grow on you.

More information about getting comfortable with GDScript or dynamically typed languages can be found in the GDScript: An introduction to dynamic languages tutorial.

What were the motivations behind creating GDScript?

The main reasons for creating a custom scripting language for Godot were:

  1. Poor thread support in most script VMs, and Godot uses threads (Lua, Python, Squirrel, JS, AS, etc.).
  2. Poor class-extending support in most script VMs, and adapting to the way Godot works is highly inefficient (Lua, Python, JS).
  3. Many existing languages have horrible interfaces for binding to C++, resulting in large amount of code, bugs, bottlenecks, and general inefficiency (Lua, Python, Squirrel, JS, etc.) We wanted to focus on a great engine, not a great amount of integrations.
  4. No native vector types (vector3, matrix4, etc.), resulting in highly reduced performance when using custom types (Lua, Python, Squirrel, JS, AS, etc.).
  5. Garbage collector results in stalls or unnecessarily large memory usage (Lua, Python, JS, AS, etc.).
  6. Difficulty to integrate with the code editor for providing code completion, live editing, etc. (all of them). This is well supported by GDScript.

GDScript was designed to curtail the issues above and more.

What type of 3D model formats does Godot support?

Godot supports Collada via the OpenCollada exporter (Maya, 3DSMax).

If you are using Blender, take a look at our own Better Collada Exporter.

As of Godot 3.0, glTF is supported.

FBX SDK has a restrictive license, that is incompatible with the open license provided by Godot. That being said, FBX support could still be provided by third parties as a plugin. (See Plugins question above.)

Will [Insert closed SDK such as PhysX, GameWorks, etc.] be supported in Godot?

The aim of Godot is to create a free and open-source MIT-licensed engine that is modular and extendable. There are no plans for the core engine development community to support any third-party, closed-source/proprietary SDKs, as integrating with these would go against Godot’s ethos.

That said, because Godot is open-source and modular, nothing prevents you or anyone else interested in adding those libraries as a module and shipping your game with them–as either open- or closed-source.

To see how support for your SDK of choice could still be provided, look at the Plugins question above.

If you know of a third-party SDK that is not supported by Godot but that offers free and open-source integration, consider starting the integration work yourself. Godot is not owned by one person; it belongs to the community, and it grows along with ambitious community contributors like you.

How should assets be created to handle multiple resolutions and aspect ratios?

This question pops up often and it’s probably thanks to the misunderstanding created by Apple when they originally doubled the resolution of their devices. It made people think that having the same assets in different resolutions was a good idea, so many continued towards that path. That originally worked to a point and only for Apple devices, but then several Android and Apple devices with different resolutions and aspect ratios were created, with a very wide range of sizes and DPIs.

The most common and proper way to achieve this is to, instead, use a single base resolution for the game and only handle different screen aspect ratios. This is mostly needed for 2D, as in 3D it’s just a matter of Camera XFov or YFov.

  1. Choose a single base resolution for your game. Even if there are devices that go up to 2K and devices that go down to 400p, regular hardware scaling in your device will take care of this at little or no performance cost. Most common choices are either near 1080p (1920x1080) or 720p (1280x720). Keep in mind the higher the resolution, the larger your assets, the more memory they will take and the longer the time it will take for loading.
  2. Use the stretch options in Godot, 2D stretching with keeping aspect works best. Check the Multiple resolutions tutorial on how to achieve this.
  3. Determine a minimum resolution and then decide if you want your game to stretch vertically or horizontally for different aspect ratios, or whether there is a minimum one and you want black bars to appear instead. This is also explained in the previous step.
  4. For user interfaces, use the anchoring to determine where controls should stay and move. If UIs are more complex, consider learning about Containers.

And that’s it! Your game should work in multiple resolutions.

If there is a desire to make your game also work on ancient devices with tiny screens (fewer than 300 pixels in width), you can use the export option to shrink images, and set that build to be used for certain screen sizes in the App Store or Google Play.

How can I extend Godot?

For extending Godot, like creating Godot Editor plugins or adding support for additional languages, take a look at EditorPlugins and tool scripts.

Also see the official blog posts on these topics:

You can also take a look at the GDScript implementation, the Godot modules, as well as the unofficial Python support for Godot. This would be a good starting point to see how another third-party library integrates with Godot.

I would like to contribute! How can I get started?

Awesome! As an open-source project, Godot thrives off of the innovation and ambition of developers like you.

The first place to get started is in the issues. Find an issue that resonates with you, then proceed to the How to Contribute guide to learn how to fork, modify, and submit a Pull Request (PR) with your changes.

I have a great idea for Godot. How can I share it?

It might be tempting to want to bring ideas to Godot, like ones that result in massive core changes, some sort of mimicry of what another game engine does, or alternative workflows that you’d like built into the editor. These are great and we are thankful to have such motivated people want to contribute, but Godot’s focus is and always will be the core functionality as outlined in the Roadmap, squashing bugs and addressing issues, and conversations between Godot community members.

Most developers in the Godot community will be more interested to learn about things like:

  • Your experience using the software and the problems you have (we care about this much more than ideas on how to improve it).
  • The features you would like to see implemented because you need them for your project.
  • The concepts that were difficult to understand while learning the software.
  • The parts of your workflow you would like to see optimized.
  • Parts where you missed clear tutorials or where the documentation wasn’t clear.

Please don’t feel like your ideas for Godot are unwelcome. Instead, try to reformulate them as a problem first, so developers and the community have a functional foundation to ground your ideas on.

A good way to approach sharing your ideas and problems with the community is as a set of user stories. Explain what you are trying to do, what behavior you expect to happen, and then what behavior actually happened. Framing problems and ideas this way will help the whole community stay focused on improving developer experiences as a whole.

Bonus points for bringing screenshots, concrete numbers, test cases, or example projects (if applicable).
