Show those Wolverines who's boss!

Ever had fun playing Duck Hunt for the Nintendo Entertainment System? Now instead of ducks you can go and make Sparty happy by zapping Wolverines to show them who is really the best university in Michigan! Take your Free Wileye camera and aim at the target to get as many hits as you can before the timer runs out!

Inspiration & How it works

I've always wanted to create a hardware hack and a game that has a physical level of interactivity to it similar to Duck Hunt on the NES. After learning Free Wili just released a brand new camera module for their hardware I joined spartahack on a whim to make this project I had in my head for awhile.

Using the Free Wili, you press the red button and aim your camera towards the wolf on the screen to attempt to zap them. When the zap is triggered, the screen turns black except for the wolf which turns white. The camera then takes a snapshot, and uses a python library to compute the ratio of white and black pixels to determine if it was a hit or a miss. You have 50 seconds to get more than 10 points (2 hits) otherwise you lose the game.

How I built it

For it's frontend, the tech stack consists of R3F, a version of React with rendering abilities from Three.js which were used to draw the sprites on the screen. The backend is more complicated, using the FreeWili API for handing hardware exceptions and libraries such as PIL, numpy for image processing and FastAPI and uvicorn for creating a websockect between the frontend and backend.

Challenges we ran into

Aside from troubleshooting the Free Wili, the biggest challenge I faced was accounting for the image processing speed. The hardware was more limited than I expected. I had to end up consulting the engineers at the Freewili team a lot through out the hackathon, but eventually I managed to make it playable. Using the lowest resolution helped speed up the processing just a little bit.

Accomplishments that we're proud of

I feel like this is pretty ambitious for a beginner level project and I'm pretty proud of what I was able to accomplish under such a short amount of time.
