# Relationship Events System - Component 34 Implementation Summary

**Date:** November 12, 2025
**Phase:** 4 - Dating System Improvements
**Status:** ✅ COMPLETE

---

## Overview

Successfully implemented a comprehensive Relationship Events System for BaoLife that transforms dating from basic interactions into an engaging relationship system with dynamic events, consequences, and monetization opportunities.

---

## What Was Implemented

### 1. Database Schema (`migrations/004_relationship_events.sql`)

Created two new tables and default event data:

#### `relationship_events` Table
- Stores event type definitions (argument, anniversary, jealousy, proposal, breakup_threat, gift_request, family_meeting)
- Contains trigger conditions, description templates, and resolution options (JSON)
- Includes priority system for event ordering
- Pre-populated with 7 event types and their options

#### `player_relationship_events` Table
- Tracks event history for each player-NPC relationship
- Records resolution choices, affinity changes, and diamond costs
- Indexed for efficient querying by player, NPC, date, and event type

**Key Features:**
- Uses prepared statements for safe column additions
- Includes comprehensive indexes for performance
- Pre-populated with default event definitions
- JSON storage for flexible resolution options

---

### 2. Core Module (`dating/relationship_events.py`)

**591 lines** of production-ready code including:

#### Event Definitions
```python
RELATIONSHIP_EVENTS = [
    # 7 event types with multiple resolution options each
    # Each option has: choice, label, affinity_change, diamond_cost
]
```

#### Core Functions

**`check_relationship_triggers(player, npc) -> Optional[Dict]`**
- Automatically checks if any events should trigger
- Evaluates multiple conditions:
  - Affinity drops (argument trigger: -15 in 24h)
  - Low affinity (breakup threat: <20)
  - High affinity (proposal: >90)
  - Anniversaries (365 days together)
  - Random events (jealousy, gift requests, family meetings)
- Respects cooldown periods to prevent spam
- Only triggers for romantic relationships

**`trigger_event(player, npc_id, event) -> Dict`**
- Creates questionEvent with answer options
- Formats description with NPC name
- Pauses game for player decision
- Preserves previous game speed

**`process_resolution(player, npc_id, event_type, resolution, affinity_change, diamond_cost) -> Dict`**
- Validates diamond balance
- Deducts diamonds if needed
- Updates NPC affinity (capped at -100 to 100)
- Records event in database
- Resumes game speed
- Returns success/failure with message

**`get_event_history(player_id, npc_id=None, limit=10) -> List[Dict]`**
- Retrieves event history for analysis
- Optionally filters by specific NPC
- Returns full event details with timestamps

**`get_relationship_stats(player_id, npc_id) -> Dict`**
- Calculates aggregate statistics:
  - Total events
  - Total affinity change
  - Total diamonds spent
  - First/last event dates

#### Helper Functions
- `get_event_by_type()` - Fetch and format event definitions
- `has_recent_event()` - Check cooldown periods
- `has_met_family()` - Track milestone completion
- `get_affinity_change_24h()` - Calculate recent affinity changes
- `get_relationship_data()` - Fetch relationship context

---

### 3. Integration Updates

**Updated `dating/__init__.py`**
- Exported 6 new functions
- Exported RELATIONSHIP_EVENTS constant
- Added to package documentation

---

### 4. Comprehensive Test Suite (`tests/test_relationship_events.py`)

#### TestEventDefinitions (4 tests)
- Validates all event definitions have required fields
- Ensures all resolution options are properly structured
- Confirms event types are unique
- Verifies diamond costs are non-negative

#### TestEventTriggering (6 tests)
- Tests argument triggering on affinity drop
- Tests breakup threat on low affinity
- Tests proposal on high affinity
- Tests anniversary triggering

- Tests cooldown periods are respected

#### TestEventResolution (5 tests)
- Tests resolution with diamond costs
- Tests insufficient diamond handling
- Tests free resolution options
- Tests negative affinity changes
- Tests affinity boundary capping (-100 to 100)

#### TestEventHistory (3 tests)

- Tests relationship statistics

#### TestHelperFunctions (8 tests)
- Tests event fetching by type
- Tests event formatting with parameters
- Tests invalid event handling

## Integration with Existing Systems

### Affinity System
- Uses existing `person.affinity` property
- Leverages existing `updateAffinity()` function
- Caps affinity at -100 to 100
- Tracks 24-hour affinity changes

### Diamond Economy
- Integrates with existing diamond system (`player.c.diamonds`)
- Logs transactions to `diamond_transactions` table
- Validates balance before purchases
- Provides monetization opportunities (20-50 diamonds per premium option)

### Event System
- Compatible with existing event infrastructure
- Uses `questionEvent` and `answerOption` classes
- Pauses game for decisions (sets gameSpeed to 100000)
- Restores previous game speed after resolution

### Database
- Uses existing database connection pooling
- Follows established migration patterns
- Leverages existing `players` and `persons` tables
- Adds relationship-specific tracking tables

---

## Performance Considerations

1. **Efficient Querying**
   - Multiple indexes for fast lookups
   - Filtered queries by player_id and npc_id
   - Limited result sets with configurable limits

2. **Cooldown System**
   - Prevents event spam with day-based cooldowns
   - Configurable cooldown periods per event type
   - Efficient date-based filtering

3. **Lazy Loading**
   - Events only trigger when conditions are met
   - No unnecessary database queries
   - Caches event definitions in memory

4. **Resource Management**
   - Proper connection handling (try/except/finally)
   - Connection pooling via existing infrastructure
   - Transaction logging for debugging

---

## Future Enhancements (Not Implemented)

The following were considered but left for future phases:

1. **Frontend Integration**
   - Relationship event modals (SwiftUI)
   - Visual feedback for affinity changes
   - Event history timeline view

2. **Additional Event Types**
   - Moving in together
   - Career conflicts
   - Financial disagreements
   - In-law drama
   - Vacation planning

3. **Advanced Features**
   - Event chain reactions
   - Personality-based event preferences
   - Seasonal event variations
   - AI-generated custom events

4. **Analytics**
   - Most common resolution choices
   - Average diamond spend per relationship
   - Event success rates
   - Player decision patterns

---

## Usage Example

```python
from dating.relationship_events import check_relationship_triggers, trigger_event, process_resolution

# In game loop, check for events
for npc in player.r:
    event = check_relationship_triggers(player, npc)
    if event:
        # Trigger event (creates question for player)
        question = trigger_event(player, npc.id, event)
        # Send to client...

# When player responds
result = process_resolution(
    player,
    npc_id='npc_456',
    event_type='argument',
    resolution='buy_gift',
    affinity_change=25,
    diamond_cost=20
)

if result['success']:
    # Update player display with result message
    print(result['message'])
```

---

## Database Migration

To apply the schema changes:

```bash
mysql -u root -p baolife_db < /home/user/lichun/ws/migrations/004_relationship_events.sql
```

The migration is idempotent and safe to run multiple times.

---

## Monetization Impact

**Diamond Spending Opportunities:**
- Arguments: 20 diamonds for gift option
- Anniversaries: 50 diamonds for luxury date
- Jealousy: 30 diamonds for grand gesture
- Breakup threats: 40 diamonds for therapy
- Gift requests: 25 diamonds for expensive gift

**Average spend per event:** ~15-20 diamonds
**Estimated events per relationship:** 10-20 per year
**Potential diamond revenue:** 150-400 diamonds/year per serious relationship

**F2P Path:** All events have free resolution options
**Premium Path:** Better outcomes with diamond purchases
