Dragon Roaster (Early 2021)

Dragon Roaster is a PC game that uses webcam-based motion tracking to let players control a dragon and roast food. The objective is simple: cook meat, avoid burning watermelon.

🔧 Tech Stack

  • Engine: Unity
  • Platform: PC
  • Input: Webcam-based body tracking
  • Languages: C#

Gameplay

  • 🔥 Control fire breath with by openning up hands
  • 🥩 Roast meat accurately for points
  • 🍉 Avoid burning watermelon

Development


        Built in one week using a simplified motion tracking setup. The angle between neck and hands controls flame power. Designed to explore quick motion-based interaction using low-cost body tracking.      

Limitations: High performance requirement; runs at ~28 FPS on GTX 1070.


Related Background Information
        

        In early 2021, the state of body tracking algorithms was primitive compared to today's standards. Major platforms like Lens Studio and Spark AR had recently introduced their first-generation AR body tracking features, while Unity provided no native body tracking SDK. The development landscape was particularly challenging due to the absence of comprehensive documentation, community tutorials, or established best practices. To overcome these limitations, I conducted extensive analysis of available codebases, reverse-engineering implementations to understand the underlying tracking methodologies and develop custom solutions for this project.
