Inspiration
The spark for this project came from a desire to create a game since I don't have all the competences, I decided to try to turn a simple facial gesture opening one's mouth into a fun gaming mechanic. I wanted to bridge the gap between Augmented Reality and classic arcade gameplay. The "Kawaii" aesthetic was chosen to give the food items (carrots, burgers, pizzas) a friendly personality,
What it does
It a simple game. The items (foods) fall and you need to catch it with your mouth. it's all for the moment.
How we built it
I developed the project within Lens Studio, focusing on three core pillars:
2D Design: Crafted a consistent visual style using custom-generated assets and stickers.
Software Development (JavaScript): Programmed a custom GameManager to handle item gravity, collision detection between the mouth and objects, and real-time score tracking.
User Experience (UX): Integrated Snapchat’s Leaderboard service to transform a solo experience into a global competition, alongside a seamless "Start/Restart" flow.
Challenges we ran into
The biggest hurdle was visual hierarchy and rendering. Getting the mouth to appear correctly layered between falling objects required a lot of trial and error with Render Layers and Z-positioning. I also had to fine-tune the "catch distance" to ensure the gameplay felt fair and responsive. Debugging TypeErrors taught me the importance of function scoping and execution order in complex scripts.
Accomplishments that we're proud of
I was proud of myself when the items start falling even if it was nothing it was my first time and I succeed to do it alone.
What we learned
This journey was a deep dive into AR game design. I significantly improved my skills in:
Game Logic: Managing update loops, randomized spawn points, and difficulty scaling (speeding up the items over time).
Script Communication: Learning how to use script.api to ensure the restart Button and Game Manager talked to each other without errors.
What's next for Catch The item
It has many possibilities like including trap like bomb into the food, use the mouth of users where we applied a fun effect instead of the 2D image etc.
