# Airplane Selection & Abilities - SETTINGS-BASED IMPLEMENTATION

**Date**: December 6, 2025  
**Status**: ✅ **COMPLETE** - Pure Settings Configuration

---

## 🎯 SIMPLIFIED ARCHITECTURE

**NO ScriptableObject assets needed!** Everything configured in `AirplaneSettings`.

### Key Changes from Previous Design:
- ❌ No `AirplaneTypeData` ScriptableObjects to create
- ❌ No ability ScriptableObjects to create  
- ✅ All configuration in `AirplaneSettings` asset
- ✅ Abilities created from settings at runtime
- ✅ Simple enum selection (Jet/Bobbing/Drop)

---

## 📋 IN-ENGINE SETUP (3 SIMPLE STEPS)

### **STEP 1: Configure Settings (5 minutes)**

Open `Tools > Settings > Airplane Settings`

You'll see **collapsible sections** for each airplane type:

#### **Jet Plane Configuration**
```
Display Name: "Jet Plane"
Prefab: [Assign jet airplane prefab]
Preview Sprite: [Assign preview image]
Ability Type: Jet
Override Mass: □ (optional)
Override Gravity Scale: □ (optional)
Override Drag: □ (optional)

Jet Ability:
├─ Ability Name: "Jet Boost"
├─ Ability Icon: [Assign icon sprite]
├─ Cooldown Duration: 5.0
├─ Jet Speed: 15.0
└─ Jet Angle: 0
```

#### **Bobbing Plane Configuration**
```
Display Name: "Bobbing Plane"
Prefab: [Assign bobbing airplane prefab]
Preview Sprite: [Assign preview image]
Ability Type: Bobbing

Bobbing Ability:
├─ Ability Name: "Air Hop"
├─ Ability Icon: [Assign icon sprite]
├─ Cooldown Duration: 3.0
└─ Bob Force: (7, 10)
    • X = Forward force (horizontal momentum)
    • Y = Upward force (vertical lift)
```

**How It Works:** Applies diagonal impulse force using Vector2 configuration. X controls forward momentum, Y controls upward lift. This gives direct control over the exact force applied in both directions.

**Examples:**
- `(0, 15)` - Pure vertical jump
- `(10, 10)` - 45° diagonal boost
- `(12, 5)` - More forward than upward

#### **Drop Plane Configuration**
```
Display Name: "Drop Plane"
Prefab: [Assign drop airplane prefab]
Preview Sprite: [Assign preview image]
Ability Type: Drop

Drop Ability:
├─ Ability Name: "Dive Bomb"
├─ Ability Icon: [Assign icon sprite]
├─ Cooldown Duration: 4.0
├─ Drop Force: 20.0
├─ Drop Distance: 5.0
└─ Zero Horizontal Velocity: ☑
```

#### **Default Selection**
```
Default Airplane Type: Jet
```

### **STEP 2: Build UI (10 minutes)**

#### Selection Panel:
```
AirplaneSelectionPanel (+ AirplaneSelectionUI component)
├── TitleText ("Choose Your Airplane")
├── JetPlaneButton
├── BobbingPlaneButton
├── DropPlaneButton
└── ConfirmButton
```

**Component Configuration:**
- Jet Plane Button → Assign button
- Bobbing Plane Button → Assign button
- Drop Plane Button → Assign button
- Confirm Button → Assign button
- Selected Color: Yellow
- Normal Color: White
- ☑ Start inactive

**NO airplane type assets to assign!**

#### Ability Button:
```
AbilityButton (+ AirplaneAbilityButton component)
├── Background (Image)
├── AbilityIcon (Image)
├── CooldownFill (Image - Radial 360)
└── CooldownText (TextMeshPro)
```

**Component Configuration:**
- Assign Button, Icon, Fill, Text references
- Ready: White, Cooldown: Gray, Active: Yellow
- ☑ Start inactive

### **STEP 3: Wire GameManager (2 minutes)**

In `AirplaneGameManager`:
- Selection UI → Assign AirplaneSelectionPanel
- Ability Button → Assign AbilityButton

**Done!** ✅

## 🎮 HOW IT WORKS

### Runtime Flow:

```
1. Game Start
   ↓
2. Show Selection UI
   - Player clicks Jet/Bobbing/Drop button
   - Confirm selection
   ↓
3. System loads config from settings
   - Gets AirplaneTypeConfig for selected type
   - Gets ability config (Jet/Bobbing/Drop)
   ↓
4. AbilityFactory creates ability instance
   - new JetAbility(name, icon, cooldown, speed, angle)
   - Ability initialized with airplane reference
   ↓
5. Airplane spawns at slingshot
   - Prefab from config
   - Physics overrides from config
   - Ability attached
   ↓
6. Player launches
   - Ability button shows with icon from config
   - Cooldown system active
   ↓
7. Player uses ability
   - Jet: Hold to fly straight
   - Bobbing: Tap to jump
   - Drop: Tap to dive
```

### Code Architecture:

```
AirplaneSettings (ScriptableObject)
├─ JetPlaneConfig (serializable class)
├─ JetAbilityConfig (serializable class)
├─ BobbingPlaneConfig (serializable class)
├─ BobbingAbilityConfig (serializable class)
├─ DropPlaneConfig (serializable class)
└─ DropAbilityConfig (serializable class)

AbilityFactory (static)
└─ CreateAbility(type, settings) → BaseAirplaneAbility
    ├─ Jet → new JetAbility(...)
    ├─ Bobbing → new BobbingAbility(...)
    └─ Drop → new DropAbility(...)

BaseAirplaneAbility (abstract class)
├─ JetAbility
├─ BobbingAbility
└─ DropAbility
```

## 📊 COMPARISON

### OLD Design (ScriptableObject-based):
```
Steps to add new airplane:
1. Create ability ScriptableObject asset
2. Configure ability in Inspector
3. Create airplane type ScriptableObject asset
4. Link ability to airplane type
5. Assign airplane type to selection UI
6. Test

Assets created: 2 per airplane type
```

### NEW Design (Settings-based):
```
Steps to add new airplane:
1. Open Settings
2. Configure airplane + ability
3. Test

Assets created: 0 (all in settings!)
```

**Result**: 66% fewer steps, 100% fewer assets! 🎉

## 🔧 EXTENDING THE SYSTEM

### Adding a 4th Airplane Type:

1. **Add enum value**:
```csharp
// AirplaneAbilityType.cs
public enum AirplaneAbilityType
{
    None,
    Jet,
    Bobbing,
    Drop,
    Glider // NEW
}
```

2. **Create ability config class**:
```csharp
// AirplaneAbilityConfig.cs
[System.Serializable]
public class GliderAbilityConfig
{
    public string abilityName = "Glide";
    public Sprite abilityIcon;
    public float cooldownDuration = 2f;
    public float glideDuration = 5f;
    // ... other fields
}
```

3. **Create ability class**:
```csharp
// GliderAbility.cs
public class GliderAbility : BaseAirplaneAbility
{
    public GliderAbility(string name, Sprite icon, float cooldown, float duration)
        : base(name, icon, cooldown)
    {
        // ...
    }
    
    public override void Execute()
    {
        // Implementation
    }
}
```

4. **Add to settings**:
```csharp
// AirplaneSettings.cs
[Header("Glider Plane")]
[SerializeField] private Data.AirplaneTypeConfig gliderPlaneConfig;
[SerializeField] private Data.GliderAbilityConfig gliderAbilityConfig;
```

5. **Update factory**:
```csharp
// AbilityFactory.cs
case AirplaneAbilityType.Glider => CreateGliderAbility(settings),
```

6. **Add UI button**:
```
Add gliderPlaneButton to selection UI
```

**Done!** No ScriptableObject assets needed.

## 🚀 MIGRATION FROM OLD SYSTEM

If you had the ScriptableObject-based system:

1. **Note your configurations** from existing assets
2. **Delete** old ScriptableObject assets:
   - Delete JetAbility.asset
   - Delete BobbingAbility.asset
   - Delete DropAbility.asset
   - Delete JetPlaneType.asset
   - Delete BobbingPlaneType.asset
   - Delete DropPlaneType.asset
3. **Open Settings** and enter values from step 1
4. **Update UI references**:
   - Selection UI no longer needs type assets
   - Remove those fields (now just buttons)
5. **Test** - Should work immediately!

---

## 💡 ADVANCED TIPS

### Inspector Organization:

Use `[Header]` attributes to create collapsible sections:
```csharp
[Header("=== AIRPLANE TYPES ===")]
[Header("Jet Plane")]
// ... jet config fields
[Header("Bobbing Plane")]
// ... bobbing config fields
```

### Default Values:

Initialize configs with sensible defaults:
```csharp
private Data.JetAbilityConfig jetAbilityConfig = new Data.JetAbilityConfig
{
    abilityName = "Jet Boost",
    cooldownDuration = 5f,
    jetSpeed = 15f
};
```

### Validation:

Add validation in `OnValidate()`:
```csharp
private void OnValidate()
{
    if (jetAbilityConfig.cooldownDuration < 0f)
        jetAbilityConfig.cooldownDuration = 0f;
}
```
