Fireflies Pixel Art VFX

Use it with your AI agent

Download this effect's ZIP, or connect the MCP to give your agent (Claude, Codex, Cursor...) the full library of pixel art effects. Then have it fill your night levels, set how many fly close to the camera, or drop the grass if your tiles have some.

Claude/Codex

You

Use fireflies.ts from Sprite Fusion's pixel art VFX to add fireflies to my night levels.

Claude

I used fireflies.ts as a reference to implement fireflies in your game.

import fireflies from "./fireflies";

const frame = { w: 320, h: 180, ox: 0, oy: 0, color: new Uint32Array(320 * 180), light: new Uint32Array(320 * 180) };
const fx = fireflies({ area: { x: 0, y: 0, w: 640, h: 360 } });

fx.update(1 / 60);
frame.color.fill(0);
frame.light.fill(0);
fx.draw(frame, "back");
fx.draw(frame, "front");
if (fx.done()) remove(fx);
