Creator Forum

Hello! So I'd like to build a creator game, but... So I asked Horizon Gen AI llama whether it is possible to do persistent placement and it said I needed clarification on whether allowing users to spawn persistent objects would be against policies?  Here's the generated:  No, it is not possible for a user to throw an entity on the ground and have it be added permanently in a world. In Horizon Worlds, entities spawned or manipulated by users are not persisted across sessions by default. When a user throws an entity, it will be simulated by the physics engine and may come to rest on the ground, but it will not be permanently added to the world. To achieve persistent entity placement, you would need to implement a custom solution using Horizon Worlds' scripting capabilities, such as using the `World.persistentStorage` API to store the entity's state and re-spawning it when the world is reloaded. However, this would require significant development effort

import { PropTypes } from 'horizon/core';import * as hz from 'horizon/core';//import { Component, Entity, Player, Vec3, CodeBlockEvents } from 'horizon/core';class Test extends hz.Component<typeof Test> {  static propsDefinition = {    destination: { type: PropTypes.Entity }, // The entity that represents the destination    triggerEntity: { type: PropTypes.Entity }, // The entity that triggers the teleportation  };  start() {    console.log("TeleportComponent TEST started");        }} hz.Component.register(Test);

How to enable users to rotate scale and otherwise transform entities in default (non local)?

 

For framing a fixed camera perfectly: Is there a way to spawn an entity at the position and rotation of the camera in editor? 

I want to display a particle effect over the CustomUI but I'm not able to because the CustomUI renders above everything even an object that is closer to the camera. The CustomUI is an overlay.Z-index is available but that only applies to elements within the CustomUI. I want to show an separate object that's NOT a CustomUI.What I've tried already:Attached the particle effect on the head anchor. Result: CustomUI still renders above everythingAttached both CustomUI and particle effect on the head anchor. Result: CustomUI won't be an overlay anymoreAgain, my question is: Is there a way to render a non CustomUI object above a CustomUI (overlay)?

How do you select the associated Asset Library object from a Hierarchy object? 

Low on gen ai credits, so only got to try this a few times (even tried a generic prompt recommended by the system), each time it was 120s of noise that actually hurts my ears! Is it borked? Does anyone know if it is possible to generate game loop music using Horizon Gen AI?  

How would you recommend creating rivers and other bodies of water in Horizon?- What's the best way to create the look of flowing water?- How to create buckets of water so the bucket looks like water?  Typically on Second Life, I'd just use an animated texture on a rectangular prism, wedged under terrain. 

Trying to figure out how to upload mesh+texture - keep running into issues like this... 

What is this strange sunburst icon in the middle of my  map? There are no objects there, it doesn't show up in the editor. But when I test this game on my phone, I see this. I'm having a ton of issues tonight with objects showing up in the editor and working fine, but not showing up on the phone...and then this weird sunshine icon that mysteriously appeared. What is this and how do I get rid of it? 

is it possible to edit the pivot after importing a model?

Is this possible? Would be AWESOME if so!!!

Can Horizon typescript access Unity namespaces?

The path c:\User\AppData\LocalLow\Meta\Horizon Worlds\Camera API Examples_630625853470378\scripts\node_modules\typescript\lib\tsserver.js doesn't point to a valid tsserver install. Falling back to bundled TypeScript version. Is there some sort of tutorial on how to properly set up vscode for hz typescript intellisense, autocomplete etc? 

How does one increase world limit?

I am trying to organizing what's becoming dozens of .ts files into their own folders, but it seems that this makes them un-findable in Desktop Editor? How do we organize file structures for projects with lots of .ts?

How do you take a screenshot on web (for sharing in the photo board gizmo)? 

Debugging this took way too long for the wrong reason, for this Unity C# dev not familiar with typescript norms, so sharing this PSA suppose you have a function that creates an entityArray from prop entities - you have to both | null the function definition argument and also add a ! when you pass the variable when calling the function: private makeEntityArray(entity: hz.Entity | null){ } makeEntityArray(this.propType.testEntity!); 

Hi - recorded a Loom to try to explain how to duplicate the editor extreme lag or "locking" - currently I am using a Razer RTX 3080Ti laptop / 32GB RAM (not as much as my macbook, but this is just a tester gamer laptop).1) generate mesh or other AI assets and start the next one before the first finishes 2) try selecting a hierarchy entity object - notice that it does not select, the entire Horizon Desktop Editor just freezesThe video is a bit long and documents an additional gen AI bug where it seems the mesh generator "gets lazy" when you use it too much (or get closer to rate limit) Jump to 2:26 to see where it happens https://www.loom.com/share/5c40ac09eaeb4f3db460944a8c121d63?sid=b032fb78-c66f-44dc-95d1-d2b85ed15a17

Well after freaking out over the missing assets, someone suggested clearing the cash on my heads set. Why? would that work. But it did!  Good luck!-jb

Hi, I’ve seen in some Horizon games that creators have included what looks like a photo gallery gizmo that people can use to upload content from those worlds. I also saw it in Horizon Central during the winter update. I’d like to know where it is in the editor, since I can’t find it under Gizmos. I'm attaching a photo from one of the games where I saw this entity.
