Meta Horizon Summer Camp world. Any documentation available on allowing multiple players for the Firefly Game? I want to add a second net.I've already added a leaderboard to track how many fireflies are caught. Fixed the OriPos. But I can't seem to get a second net added. It would be fun with a friend. 😁TIA for any direction. 

I want a door (Worlds portal) to appear when a player enters a trigger. It's set to invisible by default. Script1 makes the door visible on enter and hides it on exit, but the info panel (a child of the door) stays visible. I’d like the info panel to follow the door’s visibility automatically. Script2 treats the door and info panel as seperate objects and doesn't work. thx script1 import { Entity } from 'horizon/core';import * as hz from 'horizon/core'; class ToggleDoorVisibility extends hz.Component<typeof ToggleDoorVisibility> {  static propsDefinition = {    door: { type: hz.PropTypes.Entity },  };   start() {    const doorEntity = this.props.door!;    if (!doorEntity) return;     // When a player enters the trigger, make the door visible    this.connectCodeBlockEvent(this.entity, hz.CodeBlockEvents.OnPlayerEnterTrigger, () => {      doorEntity.visible.set(true);  &

when we have an event and we sign a couple of mods are they counting as time spent as well, or do their time not count since they are mods for the event only,

Vote on Your Top 5 Priorities from the May MHCP Creator MeetingDuring the May MHCP Creator Meeting, we reviewed a wide range of platform strengths and areas that still need improvement, everything from mobile development limitations to issues with the editor, clothing system, and IWP features.To move this feedback forward in a focused and actionable way, we’re asking creators to help identify the most important features. We've compiled all the items into a single list, and now we’re asking the community to vote on your top 5 priorities.📝 Survey Link: https://docs.google.com/forms/d/e/1FAIpQLSf8o1cTRIWP_CYcPrJokGQrJ1TTmubAxKg64gFegvN1OVUcZQ/viewform?usp=sharing&ouid=117915244616558080060This will help us understand where the greatest consensus is among creators so we can include that in our formal summary to Meta. The more creators who participate, the clearer the picture will be.Thanks for taking a minute to weigh in.

Anyone able to go over what was discussed in the Town Hall meeting? I wasn’t able to attend.

Is it possible to force the user to run continuously and block their controls so they can’t control locomotion and turning around on mobile?I'm trying to figure out how to create an infinite runner in Horizon Worlds, but from what I can see, the biggest challenge is managing player controls.Has anyone figured this out? I'd love to hear your thoughts and ideas.

I am seeing my custom NPC spawning in at zero degrees rotation, even if set to any non-zero value. This was not previously the case, up until this or last week. Anyone else notice this? workarounds?

How can our team improve the reach of the game we have created in Horizon Worlds?

Hello all. I hope I am not breaking any rules by posting this. I am new to the partner program and also the forum.I have seen many people talk about and mention the discord. I understand Meta is pushing the community towards this forum, but I feel left out by not even being able to join the discord. Even if the point is to leave the discord, it still feels like a social wall between the newer partners/creators and the old ones, which is not considered welcoming (at least here in Sweden!).If anyone wants to show me around, or at least add me somewhere where I can find fun creators to work with, please connect with me. I would appreciate that alot.All the best.

I have a memoriam world for celebrities that have passed away this year for people to gather and remember them. It's called Deaths in 2025 and I'm not able to publish it anymore. Is it possible that I have inadvertently violated community guidelines? Should I rename it and/or put an age restriction on it? THX

The die I have in my world is grabbable but the only way a player can roll is to "drop" it with the automatically assigned icon (it's in the lower left). I don't believe I am assigning throw correctly as a primary icon since nothing happens when I test it. Is there another step to this? 

Hello everyone..Wanted to know if anyone knows the reason for entering worlds with headsetsand seeing triangles with exclamation marks as well as falling through worlds? @members 

Hi Creators,I've been custom UI tutorials by "Mobile Worlds Crash Course with Laex05" and it's been awesome!! I can display custom uis.However, I want to see if the custom UIs will display differently for each player.  How do I test multiplayer either in Desktop, headset and mobile by myself? Is it possible? Or is the only to test multiplayer is to actually get someone else to test with me?Thanks!

I am learning the desktop editor.I am trying to make some more intuitive driving/flying controls then is currently being shown in "Driving Simulator", and trying to see if there is better support with the Desktop Editor. I have added a Seat AvatarPose to get the character to sit, however any inputs from the left axis control moves the player out of that pose. Is it possible to disable or better yet reassign the controls to move the asset while the character is sitting?Without having to grab an item or override?I am using a trigger gizmo at the moment on the AvatarPose. The only hints online show that I have to grab an item to override buttons, but that doesnt override the Left Axis and also grabbing something to control it is very unintuitive for the user as evidenced by interacting with a number of Worlds.

Hey everyone,My team and I worked on Crafter vs Dodgers and submitted it last week to the Meta Horizon Creator Competition.You can find our game here: https://horizon.meta.com/world/1176811227228729Our competition entry here: https://devpost.com/software/gravity-craftThis was our first time using and developing for Meta Horizon so I've got a few feedback to share in case that's useful.PROSNetworking was a cinch to use. Networking isn't our strong suit but everything worked out of the box as expected so I was surprised by that. It allowed us to create a social party game rather quickly. This is by far the strongest value IMO that Meta Horizon editor brings, which is great considering how important social is to Meta. Good work here.Gen AI was introduced to us midway through our development. We had purchased our assets before this and it was a big task to switch everything over, but we did it because Gen AI looked simply better. It was excellent at prototyping things and ge

I'd like to promote my worlds to some shy people with no VR experience or headsets.Ideally, I'd like to send them a link to a closed session for web or mobile that only has me or other people they know.I know how to open a closed session, but how do I send invites?

Took a while to find that this can be fixed from changing Motion to Animated from None(LLMs cannot figure that one outCan that be done in ts or is it DE only?

I'm trying to resize the HUD texture but it seems that it only wants to stay to the very top long rectangular strip (5:1)?Is it possible to resize to display a 1:1 map? 

I know that Meta has shown off some MR demos in Horizon Worlds. Is there a plan to open this up and provide tools to developers to create such experiences?

Sorry, first time building in MH. I've been trying to integrate an explosion from the public assets library (one of those PopcornFX asset types), but I haven't found out a way to start and stop playback of the particle effect from code.Casting to a ParticleGizmo obviously doesn't work, and the play() method doesn't resolve. I'm assuming under-the-hood it's an external Unity asset using a sprite sheet. I haven't found any documentation on this.How do I sent playback events to it?Thanks a lot!!

Since this morning, I’ve been getting the following issue: "Something went wrong, please restart the application or try again"I can't open, edit, or publish my worlds.I posted about it on Discord but haven’t gotten any replies, so I’m hoping someone here can help.We’re just hours away from the end of the competition, and I can’t leave my game in the state it should be in.The issue happened after exiting the editing mode of a world.I’m leaving a video so you can see — honestly, it’s really frustrating as a creator to have this happen on the last day of the competition with things still left to finish. 

I have a world where the sightline is quite far. Players are able to see a black lined square at the bottom edge of the world. See screenshot. I've tried turning off `Environment > Show Grid` already but that doesn't help since this isn't a grid. This is something else.How do I turn this square off? It's really jarring and doesn't fit within the world I'm building at all.
