Event Alignment
Overview
Major refactoring of the event system to create a centralized, thread-safe, and high-performance event architecture. This update establishes the EventManager as the central controller of the engine with improved event processing, tracking, and alignment.
Core Event System Improvements
EventManager Refactoring
- Thread-Safe Architecture: Redesigned EventManager for safe concurrent access
 - Central Event Controller: EventManager now serves as the primary event coordinator for the entire engine
 - Enhanced Event Processing: Improved event queuing, processing, and tracking mechanisms
 - Performance Optimizations: Streamlined event handling for better performance
 - Event Factory Integration: Added comprehensive EventFactory system for type-safe event creation
 
Event System Components
- EventFactory.cpp/hpp: New factory pattern implementation for event creation (138+ lines)
 - EventTypeId.hpp: Enhanced event type identification system
 - Event Processing Pipeline: Improved event lifecycle management and processing flow
 
AI System Alignment
Behavior System Updates
- Removed Frame Staggering: Eliminated complex frame staggering code from AI system for cleaner processing
 - Behavior Optimization: Updated AI behaviors (Chase, Guard, Patrol, Wander, etc.) for event-driven architecture
 - Entity Ownership Clarification: GameState now clearly owns all spawned entities while managers handle their lifecycle
 
AI Behavior Improvements
- ChaseBehavior.cpp: Major refactoring (131+ lines changed)
 - PatrolBehavior.cpp: Significant updates (97+ lines changed)
 - Enhanced Trigger Methods: Added new trigger methods to event manager API for AI integration
 
Build System & Performance
CMake Optimizations
- Build Performance: Significant CMake optimizations for faster compilation
 - Test Streamlining: Simplified and optimized test configuration (1116+ lines of CMake improvements)
 - Warning Elimination: Fixed multiple build warnings and compilation issues
 - Cross-Platform Fixes: Addressed Windows-specific build issues
 
Code Quality Improvements
- cppcheck Integration: Added comprehensive static analysis suppression rules
 - Unused Code Removal: Cleaned up unused includes and redundant code
 - Memory Safety: Enhanced buffer management and fixed stale buffer consumption
 
Testing & Validation
Enhanced Test Suite
- EventManagerBehaviorTests.cpp: New comprehensive behavior testing (113+ lines)
 - EventManagerTest.cpp: Expanded test coverage (335+ lines)
 - Event Scaling Benchmark: Updated performance benchmarking (146+ lines)
 - Mock System: Improved mock objects for better testing isolation
 
Test Infrastructure
- Test Script Updates: Enhanced test execution scripts for better reliability
 - Core-Only Testing: Added focused test execution options
 - Error Reporting: Improved test error detection and reporting
 
Game States & UI
State Management
- EventDemoState: Major refactoring (439+ lines) for better event demonstration
 - State Alignment: Updated all game states for consistent event handling
 - UI Integration: Enhanced UI manager integration with event system
 
Logging & Debugging
- Logger Enhancements: Added new logging macros and improved debug output
 - Debug Message Cleanup: Removed duplicate and unnecessary debug messages
 - Weather Event Logging: Added informational logging for weather event handling
 
Documentation Updates
Technical Documentation
- AGENTS.md: Updated coding guidelines and performance recommendations
 - EventManager.md: Comprehensive event system documentation updates
 - EventManager_QuickReference.md: Enhanced quick reference guide (158+ lines)
 - Performance Guidelines: Added STL algorithm preferences for better optimization
 
Breaking Changes
- Event Processing: Some event handling patterns may require updates for new architecture
 - AI Behavior Interface: Behavior classes may need adjustments for new event-driven model
 - Test Dependencies: Test infrastructure changes may affect custom test implementations
 
Performance Metrics
- Event Processing: Significantly improved event processing throughput
 - Memory Usage: Reduced memory overhead through better buffer management
 - Build Times: Faster compilation through CMake optimizations
 - Thread Safety: Enhanced concurrent processing capabilities
 
Files Changed
- Total Files Modified: 73 files
 - Lines Added: 2,844+
 - Lines Removed: 2,538+
 - Net Addition: 306+ lines (with significant refactoring)
