pixel-asset-master 0.1.0

AI-driven 2D pixel game asset generation toolkit

Pixel Asset Master — AI generates 2D pixel game assets from game design briefs

English | 中文

Drop in a game concept, art direction, or reference images — get back a structured pixel asset project with sprites, tiles, items, UI, effects, backgrounds, animation frames, sprite sheets, and export metadata.

我是一名对游戏独立开发感兴趣的大学生，这个项目的灵感来自 PPT-master。它尝试把“用结构化流程辅助创作”的思路迁移到 2D 游戏像素素材生成中，让独立开发者可以更快整理美术方向、生成素材，并保留可复用的项目规范。

Project Example

下面是一个水墨工笔像素风项目示例，包含两种树与竹子的动画展示。

Asset	Preview	Frames
Cherry Blossom Tree		6-frame sprite sheet
Willow Tree		6-frame sprite sheet
Bamboo		4-frame sprite sheet

How it works — Pixel Asset Master is a workflow skill for AI IDEs. You chat with an AI agent, confirm the style constraints, and the skill guides the agent through project setup, asset planning, generation, validation, and export.

Local-first workflow — Project files and generated assets are stored locally under projects/. API usage only depends on whatever AI tool or image provider you choose to connect.

Pixel Asset Master focuses on:

• Game-ready structure — assets are grouped by characters, tiles, items, ui, effects, and backgrounds.
• Strict visual contract — spec_lock.md records canvas size, palette, style, color budget, and forbidden rendering patterns.
• Reusable templates — built-in palettes, size presets, and sprite layout references.
• Validation tools — scripts help check palette compliance, color budget, image format, and sprite sheet export.
• Agent-friendly process — staged confirmations reduce vague prompts and keep long asset runs consistent.

Quick Start

1. Prerequisites

Dependency	Required?	What it does
Python 3.8+	✅ Yes	Runs the helper scripts
Pillow	✅ Yes	Image analysis, validation, quantization, and sprite sheet packing

Install the CLI tool with uv:

uv tool install .

This installs the pam (and pixel-asset-master) command globally. If you prefer to run without installing, use uv run pam ... from the repository root.

2. Set Up

Option A — Download ZIP: download the repository ZIP from GitHub and unzip it.

Option B — Git clone:

git clone <your-repository-url>
cd pixel-asset-master-skills
uv tool install .

3. Put It Into Your AI Coding IDE

After downloading or unzipping the repository, open the entire pixel-asset-master-skills/ folder as a workspace in your AI coding IDE.

IDE	How to use
Cursor	File → Open Folder... and select pixel-asset-master-skills/. Ask the chat agent to read skills/pixel-asset-master/SKILL.md.
Trae	Open the folder as a project/workspace. Then mention skills/pixel-asset-master/SKILL.md in chat before asking for assets.
Windsurf	Open the folder in Windsurf. Use Cascade chat and reference skills/pixel-asset-master/SKILL.md when starting a pixel asset task.
Other AI coding IDEs	Open the repository root as the workspace and point the agent to skills/pixel-asset-master/SKILL.md.

Recommended first prompt:

Read skills/pixel-asset-master/SKILL.md and help me create a pixel art asset project.

4. Create a Pixel Asset Project

pam init demo --size 32x32 --palette DB32

The generated project is saved under projects/ and is ignored by Git by default.

5. Choose Your Generation Mode

Mode A — Without Reference Images

Use this when you only have a text idea, game design brief, or art direction.

Example prompt:

Read skills/pixel-asset-master/SKILL.md.
Create a 64x64 4-direction RPG character sprite sheet.
Style: ink-wash gongbi pixel art.
Actions: idle and walk.
No reference image.

The agent should:

1. Confirm style, size, palette, facing direction, action list, and frame count.
2. Create or update projects/<project_name>/design_spec.md.
3. Create or update projects/<project_name>/spec_lock.md.
4. Generate PNG assets, animation frames, sprite sheets, and manifests.

Mode B — With Reference Images

Use this when you already have character art, tiles, UI mockups, moodboards, or screenshots that should guide the generated pixel art.

First, import reference images:

pam import-sources projects/demo_32x32_YYYYMMDD path/to/reference.png

Then prompt the AI agent:

Read skills/pixel-asset-master/SKILL.md.
Use the images under projects/demo_32x32_YYYYMMDD/images/ as visual references.
Generate matching pixel art assets and keep the same silhouette, palette mood, and style constraints.

The agent should analyze the reference images, derive style and palette constraints, then continue through the same spec lock, generation, validation, and export pipeline.

6. Validate and Export

pam validate-project projects/demo_32x32_YYYYMMDD
pam validate-assets projects/demo_32x32_YYYYMMDD
pam finalize projects/demo_32x32_YYYYMMDD --all
pam sheet projects/demo_32x32_YYYYMMDD --by-category

AI lost context? Ask it to read skills/pixel-asset-master/SKILL.md.
