World Broadcast

trying to understand the testing section of this document: https://developers.meta.com/horizon-worlds/learn/documentation/typescript/api-references-and-examples/world-broadcast/overview

 i'ver added the simple asset but have no idea if it works.

it says:

 "Testing You can test your changes in two ways: In-editor - This is the easiest workflow for checking changes as you work. Set up a trigger (e.g., a trigger zone) that activates your camera scripting when a player enters it. This allows you to see your cameras in the editor. Remember to disable this trigger before publishing! The frameworks we’ve provided has Debug Mode toggles to help with this. With real instances - When you’re ready to start integration, Meta can set up a Draft stream visible only to the world’s creators. Draft channels show only instances that the creator(s) are in. An instance can take up to 5 minutes to be prepared and selected for streaming—we’re working to reduce this delay. The Stream Controller can only see published instances, so you must publish your changes before testing. We’re working to improve this flow."

 

  1. how does the trigger activates the scripts?
    2. and let's say i published it. it says "Meta can set up a draft stream" but then... it doesn't say what do i need to do to ask meta to set it up...
    3. do i need to get any confirmation from Meta after posting my world ID on the dev forums?
    4. are there any more resources on how broadcast work and how to set it up

Hello!

For point 1, you can create a player triggered zone for the world broadcast camera using the links from SeeingBlue​. You can follow the instructions from your post to test this.

For point 2, the documentation clarifies: "With real instances - When you’re ready to start integration". This means it only applies if your world is being used for world broadcasting in a real scenario. Meta will set up a draft for you to preview when you’re implementing.

For point 3, I will check with the competition team to see if any confirmation is being provided.

For point 4, I believe SeeingBlue​'s response covers this.

Thank you for your questions!

I haven't tried it myself, but there are 2 more related articles if you haven't seen those.
I am not sure if this is working yet? I don't recall hearing anything from Meta about it being ready.
