One-line description

[Project] 👾 Procedural Pixel Art Sprite Generator & Animator

Description

Create a web-based pixel art creator and procedural asset generator using HTML, CSS, and JavaScript. The application will leverage cellular automata and symmetric random noise to automatically generate retro sprites (e.g. spaceships, monsters, items) and animate them using pixel-grid timelines.

This project introduces contributors to procedural generation logic, cellular algorithms, canvas manipulation, and timeline-based web animations.

---

Objectives

• Educate developers on procedural logic, cellular automata (Conway's rules), and random seeding.
• Provide an interactive UI for creating, generating, and exporting retro pixel art.
• Demonstrate timeline frames and sprite sheet generation techniques.

---

Key Features

1. Pixel Art Grid & Layer Editor

• A customizable canvas grid (8x8, 16x16, 32x32) where users can paint pixels with a color palette.
• Symmetry painting (horizontal or vertical mirror options) to help paint balanced sprites.

2. Procedural Generator Engine

• Seeded Generator: Clicking "Generate" procedurally spawns sprites (e.g., spaceships, weapons, shields) based on rulesets like symmetric noise, cellular boundary steps, and customizable color schemes.
• Seeded Randomness: Users can copy/paste seed strings to recreate identical procedural sprites.

3. Timeline Animator & Exporter

• Add multiple frames to animate the sprite.
• Adjust playback speed (FPS preview).
• Export sprites as a downloadable PNG sheet, CSS keyframe animation code, or GIF/Sprite map.

Tasks Breakdown

🟢 Beginner

• Implement the pixel canvas drawing board grid supporting canvas clear, basic brush/eraser tool, and simple color picker.
• Build the sidebar containing sliders for grid resolution and generator parameters.

🟡 Intermediate

• Implement symmetry mirroring logic (drawing on the left side duplicates to the right side).
• Build the frame timeline UI allowing users to add, copy, delete, and rearrange animation frames.
• Add palette presets and custom palette savers using LocalStorage.

🔴 Advanced

• Write the cellular automata/noise generation algorithm to output recognizable sprite classes (spaceships, creatures) symmetrically.
• Build the sprite sheet compiler that merges animation frames into a single downloadable PNG with corresponding CSS keyframe mapping.

Expected Outcome

An engaging tool that artists and game developers can use to brainstorm pixel assets, teaching contributors about grid arrays, bit-shifting buffers, and mathematical graphics generation.
