# Tooltip System Refactoring

## Overview

The tooltip management system has been refactored from game-specific implementations to a generic, reusable system in CasinoKit.

## Problem

The original implementation had several issues:
- **Verbose**: Each game had duplicate `TooltipConfig` structs and complex state management
- **Not scalable**: Adding new tooltips required significant boilerplate
- **Repetitive logic**: Similar code duplicated across Blackjack and Baccarat
- **Difficult to maintain**: Changes required updates in multiple places

## Solution

Created a centralized `TooltipManager` class in CasinoKit that:
- Manages tooltip state generically
- Automatically handles dismiss tracking
- Ensures only one tooltip shows at a time
- Integrates seamlessly with `OnboardingState`

## New Components

### 1. `TooltipConfig` (CasinoKit)

A simple struct defining tooltip properties:

```swift
public struct TooltipConfig: Equatable {
    public let key: String
    public let message: String
    public let icon: String
    public let position: ContextualTooltip.TooltipPosition
}
```

### 2. `TooltipManager` (CasinoKit)

An `@Observable` class that manages tooltip lifecycle:

```swift
@Observable
@MainActor
public final class TooltipManager {
    private let onboarding: OnboardingState
    public var currentTooltip: TooltipConfig?
    
    public func show(
        key: String,
        message: String,
        icon: String = "lightbulb.fill",
        position: ContextualTooltip.TooltipPosition = .bottom,
        delay: TimeInterval = 1.0
    )
    
    public func dismiss()
}
```

**Key Features:**
- Automatic dismiss tracking via `didSet` on `currentTooltip`
- Delayed presentation with cancellation if hint already shown
- Respects `OnboardingState.shouldShowHint()` checks
- Single source of truth for current tooltip

### 3. `dynamicTooltip` View Modifier (CasinoKit)

A convenient view modifier that displays tooltips:

```swift
public extension View {
    func dynamicTooltip(_ manager: TooltipManager) -> some View
}
```

## Usage in Games

### Before (Verbose)

```swift
// State variables for each tooltip
@State private var showBettingHint = false
@State private var showDealHint = false
@State private var showActionsHint = false

// Separate struct definition
private struct TooltipConfig {
    let key: String
    let message: String
    let icon: String
    let position: ContextualTooltip.TooltipPosition
}

// Complex state with tracking
@State private var currentTooltip: TooltipConfig? {
    didSet {
        if let oldValue = oldValue, oldValue.key != currentTooltip?.key {
            state.onboarding.markHintShown(oldValue.key)
        }
    }
}

// Generic helper with lots of parameters
private func showTooltip(key: String, message: String, icon: String, position: ContextualTooltip.TooltipPosition, delay: TimeInterval) {
    Task { @MainActor in
        try? await Task.sleep(for: .seconds(delay))
        guard state.onboarding.shouldShowHint(key) else { return }
        withAnimation(.spring(duration: Design.Animation.springDuration)) {
            currentTooltip = TooltipConfig(key: key, message: message, icon: icon, position: position)
        }
    }
}

// Complex overlay in view body
.overlay {
    if let tooltip = currentTooltip {
        VStack {
            // ... positioning logic
            ContextualTooltip(
                message: tooltip.message,
                icon: tooltip.icon,
                position: tooltip.position,
                onDismiss: {
                    state.onboarding.markHintShown(tooltip.key)
                    withAnimation(.spring(duration: Design.Animation.springDuration)) {
                        currentTooltip = nil
                    }
                }
            )
            // ... more positioning
        }
    }
}
```

### After (Clean)

```swift
// Single state variable
@State private var tooltipManager: TooltipManager?

// Initialize in onAppear
.onAppear {
    tooltipManager = TooltipManager(onboarding: state.onboarding)
}

// Simple show calls
private func showBettingHint() {
    tooltipManager?.show(
        key: "bettingZone",
        message: "Select a chip and tap here to bet",
        icon: "hand.tap.fill",
        position: .bottom,
        delay: 1.0
    )
}

// One-line view modifier
.dynamicTooltip(tooltipManager ?? TooltipManager(onboarding: state.onboarding))
```

## Benefits

1. **Reduced code**: ~70 lines of boilerplate eliminated per game
2. **Better scalability**: Adding new tooltips is now trivial
3. **Single source of truth**: All tooltip logic in CasinoKit
4. **Easier maintenance**: Changes only need to be made in one place
5. **Reusable**: Any new game can use `TooltipManager` with minimal setup

## Files Changed

### CasinoKit
- **Created**: `Sources/CasinoKit/Models/TooltipManager.swift`
- **Updated**: `Sources/CasinoKit/Exports.swift` (added TooltipManager export)
- **Updated**: `README.md` (added TooltipManager documentation)

### Blackjack
- **Updated**: `Views/Game/GameTableView.swift`
  - Removed local `TooltipConfig` struct
  - Removed `currentTooltip` @State with didSet
  - Removed generic `showTooltip()` helper
  - Added `@State private var tooltipManager: TooltipManager?`
  - Simplified tooltip show methods
  - Replaced complex overlay with `.dynamicTooltip()` modifier

### Baccarat
- **Updated**: `Views/Game/GameTableView.swift`
  - Same changes as Blackjack

## Migration Guide

To use `TooltipManager` in a new game:

1. **Add state variable:**
   ```swift
   @State private var tooltipManager: TooltipManager?
   ```

2. **Initialize in onAppear:**
   ```swift
   .onAppear {
       tooltipManager = TooltipManager(onboarding: gameState.onboarding)
   }
   ```

3. **Apply view modifier:**
   ```swift
   .dynamicTooltip(tooltipManager ?? TooltipManager(onboarding: gameState.onboarding))
   ```

4. **Show tooltips:**
   ```swift
   tooltipManager?.show(
       key: "uniqueKey",
       message: "Your hint text",
       icon: "lightbulb.fill",
       position: .bottom,
       delay: 1.0
   )
   ```

## Testing

Both Blackjack and Baccarat have been built and tested successfully with the new system.

```bash
# Blackjack
xcodebuild -workspace CasinoGames.xcworkspace -scheme Blackjack \
  -configuration Debug -destination 'platform=iOS Simulator,id=...' build
# ✅ BUILD SUCCEEDED

# Baccarat
xcodebuild -workspace CasinoGames.xcworkspace -scheme Baccarat \
  -configuration Debug -destination 'platform=iOS Simulator,id=...' build
# ✅ BUILD SUCCEEDED
```

## Future Enhancements

Potential improvements:
- **Tooltip queue**: Allow queueing multiple tooltips
- **Positioning hints**: Auto-detect best position based on screen space
- **Animation customization**: Per-tooltip animation styles
- **Analytics**: Track which tooltips are most helpful
