Congrats to the prize winners!
Congratulations to all the mobile game prize winners. Although I was not one of the winners (😔), as an experienced TypeScript developer, I really liked learning the Horizon Worlds API and development tools. If you need help with future projects, please keep me in mind. And visit my contest entry, Galactic Treasure Hunt, to add to my milestones! https://horizon.meta.com/world/652276037540703/?locale=en_USMobile Competition Submission Deadline: Q&A Support
Hey Creators! With the Mobile Competition submission deadline just around the corner, we want to make sure you have all the support you need to get your worlds submitted on time. Important Reminders: Submission Deadline: May 8, 2025 @ 11:45pm (PT) / 1:45am (CT) / 2:45am (ET) Make sure to review the official competition rules and guidelines before submitting your world If you encounter any technical issues during submission, please let us know ASAP so we can assist you To help with any last-minute questions or concerns, we're creating this thread as a dedicated space for you to ask anything related to submitting your worlds for the competition. 💭 Whether you're wondering about: Technical questions and troubleshooting Submission guidelines and requirements Or anything else that's on your mind Critical Warning: Publishing a World as Non Discoverable and then switching to Discoverable Automatically Enables Members Only Option in the Desktop Editor Please be aware that there is currently a bug in the Desktop Editor which can have implications when publishing your world. If you have published your world, with Discoverable set to off, setting Discoverable to on in the Publishing modal in the Desktop Editor will automatically switch Members-Only to on. Please make sure that you switch Members-Only to off before you publish your update, as judges will not be able to judge your world if it is set to Members-Only, and it must be available to play on mobile. If you are impacted by this issue please alert us as soon as possible in the submission thread. Good luck with your submissions, and we look forward to seeing your amazing creations! Post Your Questions Below!Persistent Spawned Objects?
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 and may not be feasible or allowed by the platform's policies. Here's an example of how you might implement a basic persistent entity system: ```typescript import { PropTypes, CodeBlockEvents, Player, Vec3, Quaternion } from 'horizon/core'; import { Component, Entity, World } from 'horizon/core'; class PersistentEntity extends Component<typeof PersistentEntity> { static propsDefinition = { entityToPersist: { type: PropTypes.Entity }, }; start() { this.connectCodeBlockEvent(this.entity, CodeBlockEvents.OnPlayerEnterWorld, this.onPlayerEnterWorld.bind(this)); this.connectCodeBlockEvent(this.entity, CodeBlockEvents.OnGrabEnd, this.onEntityReleased.bind(this)); } onPlayerEnterWorld(player: Player) { const storedState = this.world.persistentStorage.getPlayerVariable(player, 'persistentEntity'); if (storedState) { const entity = this.props.entityToPersist!; entity.position.set(new Vec3(storedState.position.x, storedState.position.y, storedState.position.z)); entity.rotation.set(new Quaternion(storedState.rotation.x, storedState.rotation.y, storedState.rotation.z, storedState.rotation.w)); } } onEntityReleased(player: Player) { const entity = this.props.entityToPersist!; const position = entity.position.get(); const rotation = entity.rotation.get(); // Store the entity's state in persistent storage this.world.persistentStorage.setPlayerVariable(player, 'persistentEntity', { position: { x: position.x, y: position.y, z: position.z }, rotation: { x: rotation.x, y: rotation.y, z: rotation.z, w: rotation.w }, }); } } Component.register(PersistentEntity); ``` Please note that this is a simplified example and may not cover all edge cases. You should consult the Horizon Worlds documentation and consider factors like entity ownership, security, and performance when implementing a persistent entity system.It's Not Too Late to Join the Competition!
