Array Populator (Editor) – Bulk Array & List Populator Tool for Unity

Array Populator (Editor) is a professional-grade Unity Editor extension designed to dramatically speed up your workflow when filling serialized arrays or lists in Components, ScriptableObjects, or custom tools.
Whether you’re working with GameObjects, MeshRenderers, AudioClips, Textures, or ScriptableObjects, this tool allows you to bulk-assign all required elements automatically — in seconds.

It’s the perfect solution for environment artists, technical designers, and programmers who often manage large sets of serialized data inside Unity.

Key Features

Populate from Multiple Sources

• Scene Selection: Instantly add all selected objects or components in the scene.
• Parent & Children: Auto-fill arrays with all child objects under a selected parent.
• Folder Import: Collect all prefabs, textures, audio clips, or any assets inside a folder.
• Drag & Drop: Manually drag GameObjects or assets directly into the window.

Smart Options

• Append or Replace: Choose whether to add new elements or clear existing ones.
• Unique Filter: Automatically remove duplicates.
• Sort A→Z or Shuffle: Organize your arrays alphabetically or randomize them.
• Undo Support: Every populate action is Undo-safe.

Component Auto-Detection

• Works seamlessly with fields like List<MeshRenderer> or GameObject[].
• Detects matching component types automatically when populating from prefabs or scene objects.

Clean, Productive UI

• Organized EditorWindow accessible via Tools → Array Populator.
• Context menu shortcut: Right-click any Component → Populate Arrays/Lists…

Safe and Editor-only

• Fully Editor-exclusive — no runtime overhead or dependencies.
• Undo, validation, and asset references are all Unity-native.

Typical Use Cases

• Quickly filling a List<MeshRenderer> or List<Collider> for batch operations.
• Assigning all prefabs in a folder to a ScriptableObject reference list.
• Populating texture or audio banks for content-heavy scenes.
• Auto-linking children GameObjects (e.g., level nodes, checkpoints, waypoints).
• Preparing datasets for procedural systems or custom tools.

How It Works

1. Open Tools → Array Populator.
2. Select your Target GameObject, Component (script), and the array/list field.
3. Choose a Source Type (Selection, Parent & Children, or Folder).
4. Configure options (Append, Unique, Sort, Shuffle).
5. Click Apply — your field is populated automatically.
6. Review results and Undo if needed.
