SDK7 alpha testing guidelines

SDK version 7 is currently being tested as an alpha release. We’re gathering feedback from the community, to ensure the release doesn’t present any major issues and that the experience of using it is good.

We encourage you to test and experiment with this new SDK as much as possible, but please don’t build any events or important scenes that rely on content written with SDK7. As things are still in a alpha stage, breaking changes are still possible.

Documentation #

Find the full documentation for SDK7 in under the SDK7 section of the documentation.

Using the playground #

To try out SDK7, visit the playground. Write SDK7 code on the left of the screen, and see the resulting scene on the right. As you change the code, the scene is updated automatically.

If you run into any issues, please copy a URL to the current setup of your scene with the Share button, and report an issue including that link to your code.

Running in preview #

To run a scene using SDK7 in preview

  1. Make sure you have the latest version of the Decentraland command line
  2. In a new directory, create a new SDK7 project
    dcl init --template https://github.com/decentraland/sdk7-scene-template/archive/refs/heads/main.zip
    
  3. Run previews with dcl start, the same as with older versions. Edit or add any additional files you want into the folder structure to build out your scene.
📔 Note: Notice that scenes that use SDK7 don’t have the decentraland-ecs package installed. Instead, they have the @dcl/sdk package.

In production #

You can deploy scenes with SDK7 using dcl deploy the same as any scene with SDK6.

📔 Note: Please note that this is not yet a stable version. Breaking changes are possible, so avoid using this version for scenes that are of critical importance.

Pending features #

The SDK7 alpha includes almost complete feature parity with everything that’s possible with older versions of the SDK. A few features have been left out of the initial scope, in order to tackle them before the first official non-alpha release. The following features are not available in the current alpha:

  • Video texture
  • Textures on UI elements
  • Button events on UI elements
  • Input boxes on the UI
  • Trigger the playing of an emote on the avatar

A couple of features are intended to be re-implemented in future releases following Data Oriented Programming principles. These for now are still exposed as legacy functions that are marked as deprecated.

  • Functions to get player data, like getUserData, getPlayersInScene, or
  • Functions to get data about the context, like getDecentralandTime, getCurrentRealm, getPlatform, getPortableExperiencesLoaded
  • Observables for player events like onEnterSceneObservable, onLeaveSceneObservable, onPlayerExpressionObservable, onPlayerClickedObservable, onPointerLockedStateChange, onIdleStateChangedObservable, or onProfileChanged
  • Observables for other events like onSceneReadyObservable, onRealmChangedObservable
  • The MessageBus

Reporting issues #

See the list of existing known issues here.

If you run into any bugs, please report an issue in the SDK repository.

We ask you to please detail how to reproduce the issue as much as possible. The ideal way to report a bug is to include a link to the playground, showcasing a minimal scene where this issue can be observed. Click the Share button in the playground to copy a URL that includes the code that you’re currently using. That way, the issue is 100% reproducible by whoever is debugging it.

Submit feedback #

Once you’ve had a chance to try the new SDK, please fill in the feedback form.
