In-World Party Travel System

Inspiration

The frustration of losing friends in virtual worlds inspired us to create a seamless group travel experience. In Meta Horizon Worlds, coordinating group movement often breaks immersion and separates players. We wanted to solve the age-old VR problem: "Wait, where did everyone go?"

What it does

The Party Teleporter creates intelligent group teleportation in VR.

When a player enters a teleporter trigger, nearby friends (within 100m) receive an elegant UI prompt asking to join the journey.
The system handles everything automatically: detecting nearby players, managing responses with countdown timers, and teleporting willing participants together while respecting individual choice.

How we built it

Built using TypeScript for Meta Horizon Worlds, we created two main components:

PartyTeleporter System: Handles trigger detection and teleportation logic
PartyJoinUI: Custom UI with player-specific bindings

Key features include:

Radius-based player detection
Request timeout management
Cooldown systems to prevent spam
Responsive UI with accept/decline buttons and countdown timers

Challenges we ran into

Managing asynchronous player responses across multiple users simultaneously
Implementing player-specific UI bindings without conflicts
Handling edge cases like players leaving mid-request
Balancing spam prevention with accessibility
Extensive testing of timing systems to maintain immersion

Accomplishments that we're proud of

Created a polished, intuitive group travel system that feels natural in VR
Designed an elegant UI with smart anti-spam protection
Implemented flexible party size management (2–8 players)
Built a plug-and-play teleportation system where players can join simply by entering any trigger

What we learned

VR social interaction design requires careful attention to timing and user agency
The importance of immediate feedback and clear visual communication
Respecting player choice in multiplayer interactions
Managing state across multiple concurrent users improved our skills in asynchronous programming and UX design for shared virtual spaces
