Aquarium by Roberto ⌘ CO·DERS

Project Description

Can AI simulate realistic animal behavior? :) Notice how the fish gets more reactive and aggressive as they get hungrier. They will chase food to beat the others. Can you spot the largest... poo?

Initial Prompt

I want to build an app in p5.js that simulates an acquarium. Please generate code that I can copy and paste into the p5.js editor. Let's start with the background, I want a blue gradient, sand, pebbles and a few plants. Great! Now let's add a few fish. I want them to be able to turn around and swim realistically.

Project Development Snapshots

Preparing the aquarium with sand, pebbles, and plants. Only at the very end I played with the app constants and multiplied the plants by 100!

The first fish! Gemini created a lovely variaty of sizes and colors!

Adding food

Adding a ton of food and trying to fix the 360 rotations of the fish

Lessons Learned

What worked: 2D fish are incredibly easy to draw and they look good. The final result is awesome, in my opinion! Easy to change paramters and configure your own aquarium.
What needed help: I ton of tweaking to the the fish to turn around and swim realistically.

About Me

When I don't code for work, I code for fun! On CO-DERS I like to post some of the results of my vibe coding sessions, as I learn how to build with AI.

I'm rediscovering the origins of my passion for coding: creating something new, visually appealing, with surprising behaviors and functions.
