Easy AssetBundle Builder

Easy AssetBundle Builder is a powerful custom Editor tool for Unity that streamlines the process of creating, organizing, analyzing, and building AssetBundles. It replaces Unity's default manual workflow with a visual, data-driven system designed for professional production pipelines.

Unlike the default workflow, which relies on heavy manual configuration and inspector tags, this tool provides full visibility and control through a dedicated interface.

Benefits:
- Visual Group-Based Management: Organize assets in logical tabs.
- Per-Asset & Per-Group Control: Fine-tune build settings for individual items or entire groups.
- Built-in Versioning: Simple but powerful version tagging for assets and groups.
- Deep Dependency Analysis: Automatically map and inspect asset dependencies.
- Duplicate Detection: Instantly identify and resolve assets duplicated across multiple bundles.
- Comprehensive Metrics: Track build time, total size, and per-bundle sizes for every platform.
- Multi-Platform Targeting: Build for all target platforms from a single window.
- Multiple Compression Modes: Choose from various compression algorithms.

Features in Detail

1. Group-Based Workflow
Manage assets in a flexible, tab-based system.
- Create multiple groups with separate tabs.
- Automatic tab wrapping for an uncluttered UI.
- Independent sorting options per group.
- Assign a unique version number to an entire group.

2. Individual Asset Control
Maintain precise control over every asset in the list. Each asset supports:
- A custom, override label.
- A custom, override version number.
- Automatic detection of duplicate bundle names with an Auto-Fix option.
- The ability to be skipped or ignored during the build process.

3. Versioning System
Implement a clear versioning strategy (e.g., Player_v3).
- The version suffix can be toggled globally to be applied or ignored during the build.

4. Sorting Modes
Quickly reorganize your view with multiple sorting modes.
- Individual Asset Sorting:
- None (Manual Drag & Drop)
- Name (Ascending / Descending)
- Type
- Date Added (Newest / Oldest First)
- Dependency View Sorting:
- Name (Ascending / Descending)
- Size (Largest / Smallest First)
- Type

5. Build Metrics
After every build, the tool provides instant, actionable data:
- Total build time (in seconds).
- Overall build size.
- A detailed breakdown of individual bundle sizes.
- Persistent per-platform size tracking for historical comparison.

6. Dependency Analyzer
Gain full visibility into what makes up your bundles.
- Utilizes AssetDatabase.GetDependencies(assetPath, true) to map all dependencies.
- Displays a clear list of every dependent asset and its file size.
- Click-to-Ping functionality to instantly locate any asset in the Project view.

7. Duplicate Detection System
Prevent asset bloat by identifying dependencies shared across multiple groups.
- The system builds a dictionary: Dependency to Group to Asset List.
- Dependencies used in multiple groups are flagged with a color-coded severity scale:
- Yellow: Used in 2 groups.
- Orange: Used in 3+ groups.
- Red: Indicates a high-impact, heavy duplication.

8. Output Folder Management
Streamlined management of your build destination.
- Automatically create the target output folder if it doesn't exist.
- Safely clear the output folder before a new build.
- Automatically refresh the AssetDatabase after a build.
- Auto-select the newly built bundle in the Project view for quick access.

9. Drag & Drop System
A fast and intuitive way to populate your groups.
- Supports dragging and dropping single assets.
- Supports dragging and dropping entire folders.
- Performs recursive asset discovery on dropped folders.
- Automatic filtering to ensure only valid asset types are added.

10. Undo Support
Work with confidence, knowing every action is reversible.
- Uses Undo.RecordObject(...).
- Fully integrated with Unity's native Undo system (Ctrl+Z / Cmd+Z).
