How to Create Pixel Art Characters with AI

In this tutorial, you'll learn a fast and repeatable way to create consistent pixel art character sprites using AI. We'll use SpriteCook to go from concept to a usable character in minutes.

What you'll build

• A base character sprite at your target resolution (e.g. 32×32 or 64×64)
• A consistent style that you can re-use for more poses
• A simple pipeline you can automate later

1) Set your theme first

The theme locks in the overall style, mood, and visual direction for your entire character set. This is the foundation that keeps all your sprites consistent.

In SpriteCook, set your theme before generating anything. You can use a preset or write your own detailed description.

Example theme:

Futuristic urban dystopia with sleek tech and grime. 
Blade Runner-inspired lighting: neon pinks, cyans, 
and deep purples cutting through rain-soaked streets. 
Surfaces mix reflective chrome with scratched polymer. 
Character silhouettes defined by light contrast and geometric fashion.

Once set, the theme stays active for all subsequent generations, so you don't need to repeat style details in every prompt.

2) Describe your character

With the theme locked in, your prompt only needs to describe the character itself. Keep it short and focused on unique traits.

Example prompt:

Female protagonist, left arm fully chromed

That's it. The theme handles the style, lighting, and atmosphere. Your prompt just adds the character details.

3) Configure pixel art settings

Before generating, set your pixel art constraints:

• Pixel Art mode: Enable this for authentic pixel art
• Resolution: Start with 64×64 or 128×128 for characters (you can scale down later)
• Color palette: Choose 4-16 colors for cohesive results (this is guidance, not a hard limit)
• Background: Transparent for sprites, or white for preview

Keep these settings consistent across all characters in your set.

4) Generate and review

Generate your character. Review the result against your theme. If something feels off, make small prompt edits rather than changing the theme.

5) Export and test in engine

Export as PNG. Test in your engine (Unity, Godot, Phaser) at 1x, 2x, and 3x scale to confirm readability and collision boxes.

Creating consistent variations

Once you have a base character you like, you can use it as a reference to create consistent variations. This lets you generate different poses, outfits, or expressions while maintaining the same style and character identity.

We'll cover the reference workflow in detail in a follow-up guide, but the key is: save your first character, then use SpriteCook's "Use as Reference" feature when generating new poses or variations.
