# Automated Prefab Generation Pipeline

## Overview
This system automates the creation of monster prefabs from CSV data. No manual prefab setup required!

## How It Works

1. **CSV Data** → **ScriptableObject (SO)** → **Prefab** (automatically generated)
2. Template prefabs define required components and defaults
3. CSV importer creates complete prefabs with mesh, components, and SO references

## Setup Instructions

### Step 1: Create Template Prefab

1. In Unity, go to `Tools > Data > Create Monster Template`
2. This creates `Assets/Data/Templates/MonsterTemplate.prefab`
3. The template includes all required components:
   - NetworkObject
   - EnemyUnit
   - MonsterDataComponent (links to SO)
   - NavMeshAgent
   - EnemyAIController
   - CapsuleCollider
   - MeshFilter & MeshRenderer

4. **Customize the template if needed:**
   - Adjust default AI behavior
   - Set default collider size
   - Add visual effects
   - Configure NavMeshAgent settings

### Step 2: Update CSV with Mesh Path

Add `meshPath` column to your `Monster.csv`:

```csv
id,name,memo,moveSpeed,maxHp,atkRange,atkDamage,atkIntervalSec,meshPath,cost,weight
101,Grunt,Basic Monster,2.6,30,1,3,1.2,Assets/Models/Monsters/Monster101.fbx,1,1.0
102,Fast,Fast/Weak,3.4,18,1,2,1,Assets/Models/Monsters/Monster102.fbx,2,0.5
```

### Step 3: Import Data

1. In Unity, go to `Tools > Data > Import All CSV`
2. The importer will:
   - Create/update SO files in `Assets/Data/ScriptableObjects/Monster/`
   - Create/update prefabs in `Assets/Prefabs/Monster/`
   - Apply mesh from `meshPath` column
   - Link SO reference to prefab's MonsterDataComponent

### Step 4: Use Prefabs

Your generated prefabs are ready to use! Example with EnemyPortal:
- Open EnemyPortal prefab
- Click "Load Monster Data" button
- All monster prefabs are automatically loaded

## File Structure

```
Assets/
├── Data/
│   ├── ScriptableObjects/
│   │   └── Monster/          # SO files (generated from CSV)
│   └── Templates/            # Template prefabs (created once)
│       └── MonsterTemplate.prefab
├── Prefabs/
│   └── Monster/              # Generated monster prefabs
│       ├── Monster101.prefab
│       ├── Monster102.prefab
│       └── ...
└── GameData/
    └── Monster.csv           # Source data (editable)
```

## Benefits

- ✅ **One source of truth**: Edit CSV, everything updates
- ✅ **No manual setup**: Prefabs generated automatically
- ✅ **Designer-friendly**: Templates visual, CSV simple
- ✅ **Error-proof**: All components guaranteed to exist
- ✅ **Easy customization**: Edit template once, applies to all

## Customization

### Adding New Components
1. Open `MonsterTemplate.prefab`
2. Add the component
3. Configure defaults
4. Save template
5. All future imports will include it

### Modifying Existing Monsters
- Edit the prefab directly (changes persist on next import)
- OR modify CSV and re-import (will update SO link and mesh)

### Creating Other Data Types
Use the same pattern:
1. Create template: `Tools > Data > Create Tower Template`
2. Add meshPath column to Tower.csv
3. Import: `Tools > Data > Import All CSV`

## Troubleshooting

**Prefab not created?**
- Check if template exists in `Assets/Data/Templates/`
- Verify `meshPath` column in CSV

**Mesh not showing?**
- Verify `meshPath` is correct in CSV
- Check that mesh file exists at specified path

**Components not configured?**
- Edit template prefab
- Re-import CSV to apply template changes to new prefabs

**Want to keep manual prefab edits?**
- Prefabs created by importer are NOT overwritten
- Edits persist on next import (SO and mesh only update)
