It’s pretty surprising how far you can get with pure code.
A small look at a Terraria mod I’m building. The laser, the glow, and the sparks are all generated from code and math instead of art assets. Still early, but it’s coming together.
Delivery vs Zombies is my entry for the Rive Halloween Challenge with Contra. 🧟🍕
A one-level runner set in Buenos Aires on a full-moon night: Matilda has to deliver a pizza through a city full of zombies, with werewolves howling from the rooftops and fog rolling in, for an app that never stops rushing her. At the end, the app prints your receipt, with deductions.
Made from scratch over nine days for this challenge:
Rive CLI: the whole file written in RML from the terminal with Claude Code. 291 commits, checking every change with headless screenshots and pushing back and forth with the Editor.
GPU Canvas: a custom WGSL shader for film grain, chromatic aberration and lens blur, tuned to hold 60 fps.
Scripting for the game loop and physics, Data Binding to dress every zombie at random, State Machines for characters and UI.
The agent was fast, but its art came out generic. So it blocked out the shapes, and I redrew, rigged and animated everything by hand in the Rive Editor, adapting Vero Beltrán's original characters so they read from far away. Matilda squashes on every landing, the zombie bite runs 52 frames, your scooter parts stay where you got caught, and the receipt prints line by line. The UI comes from a design system I built in Claude Design. Original chiptune music.
Playtested with friends until the jumps felt right. English and Spanish, effects and audio can be switched on and off while you play. Desktop only for now.
Let me know if you make the delivery on time. 😅
