TagRoyale

Inspiration

As four computer science students who spend countless hours in front of screens, we wanted to create a fun and interactive way to stay active. Imagine your favourite recess game combined with the intense competition of Fortnite Battle Royale bringing you an exciting, fast-paced challenge to enjoy with friends. What could be more fun?

What It Does

TagRoyale is a location-based mobile game that transforms traditional tag into a more immersive experience. Players join a virtual lobby, enter a designated play area, and compete in real-time using their smartphones as tracking devices. The app uses GPS to monitor player positions, automatically detects when a "tag" occurs based on proximity, and provides real-time updates on game status.

Features:

Real-time player tracking on an interactive map
Geographical facts about playing location powered by Wolfram Alpha
Automated tag detection system using geolocation
In-game timer
A shrinking safezone/boundary
Multiplayer gameplay
Customizable game settings for duration and tag mechanics

How We Built It

TagRoyale is built using React Native with TypeScript. We used:

React Navigation for screen management
React Native Maps for location visualization
Context API for state management across the app
Geolocation services to track players in real-time
WebSockets for multiplayer synchronization

Challenges We Ran Into

React Native has limitations we were not expecting such as not as accurate location data and inability to use technologies and libraries that other frameworks can
