Flow-field particles · aion-2.0

Using the pre-provided p5.min.js (global p5, instance or global mode), create a full-screen flow-field particle animation: thousands of particles advected by Perlin-noise vectors, leaving fading trails, with colors shifting over time.

Using the pre-provided p5.min.js (global p5, instance or global mode), create a full-screen flow-field particle animation: thousands of particles advected by Perlin-noise vectors, leaving fading trails, with colors shifting over time.

Let me outline the requirements:

1. Single self-contained file: index.html
2. CSS in <style> tag, JS in <script> tag
3. No external resources/CDNs - fully sandboxed
4. Load p5.min.js from local file with <script src="p5.min.js">
5. Full-screen flow-field particle animation
6. Thousands of particles advected by Perlin-noise vectors
7. Fading trails
8. Colors shifting over time

Let me write this out.

bash {"command":"ls /tmp/ws/p5.min.js 2>/dev/null && echo \"EXISTS\" || echo \"NOT FOUND\""}
toolResult

/tmp/ws/p5.min.js EXISTS

assistant
thinking
No, I output the response after the  tag. The thinking is just for me.

Now let me build this flow-field particle animation. I need to create index.html with:
- p5.min.js loaded via <script src="p5.min.js"></script>
- Full-screen canvas
- Thousands of particles
- Perlin noise flow field
- Fading trails
- Shifting colors

Let me write the complete file.

write /tmp/ws/index.html (2238 bytes)
toolResult

Successfully wrote 2238 bytes to /tmp/ws/index.html

The response continues after the  tag, but the final response is always disclosed.

The user asked me to build a single-page web app with p5.js for a flow-field particle animation. I've written the file. Let me verify it exists and is correct.

bash {}
toolResult

Validation failed for tool "bash": - command: must have required properties command Received arguments: {}

assistant
thinking
The user sees only the content inside the  tag.

I have written the index.html file. Let me verify it's in place.

bash {"command":"ls -la /tmp/ws/index.html"}
toolResult

-rw-r--r--. 1 node node 2238 Aug 1 20:24 /tmp/ws/index.html

The file `index.html` has been created at `/tmp/ws/index.html` (2238 bytes). It contains a complete self-contained single-page app with: - **p5.min.js** loaded via `<script src="p5.min.js"></script>` - Full-screen canvas that resizes with the window - **3000 particles** advected by a 3D Perlin noise flow field (using `noise(x * scale, y * scale, frameCount * zSpeed)`) - **Fading trails** via a semi-transparent background rect drawn each frame (`fill(0,0,5,12)` over the whole canvas) - **Shifting colors** — hue cycles over time (`colorOffset`), with per-particle hue derived from position + time offset, saturation and brightness also modulated by noise for organic variation - Particles wrap around edges seamlessly To view it, open `/tmp/ws/index.html` in a browser. No external network or CDN required — everything runs sandboxed.

EVALUATION

3/5 working

Flow-field particle trails render nicely with color shifts, but fade out quickly leaving mostly black frames; no reaction to input.

Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
