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)

This update represents a major architectural improvement to the HammerEngine, establishing a robust foundation for scalable event-driven game development.
