Asset Creation Workflow
1. AI Image Generation (Primary Tool)
Use the skill for rapid asset creation:
gemini-image-generatorbash
# From the gemini-image-generator scripts directory:
python generate.py --prompt "[DETAILED PROMPT]" --output [filename].pngPrompt Engineering for Game Assets:
Structure: [Subject] + [Style] + [Composition] + [Technical] + [Mood]
Example for Farming in Purria Simulins:
"cute low-poly geometric bee game character, faceted crystalline wings,
big adorable eyes, bold yellow and gold with subtle gradients,
3/4 angle view, transparent background, phase 2 evolution,
developing features, partial crystalline wings"2. Asset Categories & Specs
| Category | Formats | Sizes | Notes |
|---|---|---|---|
| UI Icons | PNG-24, SVG | 64x64, 128x128 | Transparent BG, 2px padding |
| Sprites | PNG-24, WebP | Power of 2 | Sprite sheets preferred |
| Backgrounds | WebP, AVIF | 1920x1080, 2560x1440 | Layered for parallax |
| Simulins | PNG-24 | 128/192/256px by phase | 3 evolution phases |
| Cards | PNG-24, SVG | 180x252 (2.5:3.5) | Print-ready at 300dpi |
| Particles | PNG-24 | 32x32, 64x64 | Additive blend ready |
3. Style Guide: Farming in Purria
Visual Pillars:
- Low-Poly Geometric - Faceted shapes, clean edges, visible polygons
- Crystalline Accents - Translucent gem-like wings, prismatic reflections
- Kawaii Charm - Big expressive eyes, cute proportions, personality
- Bold Colors - Vibrant palettes with subtle gradients

Optimization Standards
Web/Mobile Performance
| Asset Type | Max Size | Format Priority | Lazy Load |
|---|---|---|---|
| Hero Images | 200KB | AVIF > WebP > PNG | No |
| UI Sprites | 100KB | WebP > PNG | No |
| Backgrounds | 300KB | AVIF > WebP | Yes |
| Icons | 10KB each | SVG > WebP | No |
| Animations | 500KB | Lottie > GIF | Yes |
Sprite Sheet Guidelines
Layout: Grid-based, power-of-2 dimensions
Padding: 2px between frames (prevents bleeding)
Naming: [simulin]_phase[1-3].[ext]
Atlas: Generate JSON metadata for programmatic accessResponsive Asset Strategy

/1x (base - mobile)
/2x (retina - tablet/desktop)
/3x (high-DPI - optional)Use element or CSS image-set() for delivery.
<picture>Implementation Patterns
React Integration
tsx
// Optimized image component pattern
const GameAsset = ({ src, alt, priority = false }) => (
<img
src={src}
alt={alt}
loading={priority ? "eager" : "lazy"}
decoding="async"
className="crisp" // for low-poly art
/>
);CSS for Game Assets
css
/* Crisp rendering for low-poly assets */
.crisp {
image-rendering: crisp-edges;
image-rendering: -webkit-optimize-contrast;
}
/* Smooth scaling for gradients */
.smooth {
image-rendering: smooth;
image-rendering: high-quality;
}
/* Sprite animation */
.sprite-animate {
animation: sprite-play 0.8s steps(8) infinite;
}Troubleshooting Guide
| Issue | Cause | Solution |
|---|---|---|
| Blurry assets | Wrong resolution | Use 2x assets, check devicePixelRatio |
| Color banding | 8-bit limitation | Use PNG-24, add subtle dithering |
| Jagged edges | No anti-aliasing | Enable AA in source, or use SVG |
| Large file size | Unoptimized | Run through squoosh.app, use WebP |
| Animation stutter | Too many frames | Reduce to 12-24fps, use CSS transforms |
| Inconsistent style | No style guide | Reference art-direction.md, use AI consistently |
Quality Checklist
Before shipping any asset:
- Correct dimensions and format
- Optimized file size (within limits above)
- Transparent background where needed
- Consistent with low-poly crystalline style
- Tested on 1x and 2x displays
- Named according to convention
- Metadata/atlas generated if sprite
