StrikeEngine

A C++17 game engine built on OpenGL 4.3, featuring an XML-driven scene system, ECS architecture, physics simulation, and spatial audio. StrikeEngine is a learning and research project.

Features

• XML Scene System - Define your entire scene in a single .xml file: entities, components, assets, lighting, fog, and skybox
• C++ Scripting - Similar to Unity
• Clustered Forward Rendering - OpenGL 3D world rendering - shader implementation based on Dave H's clustered shading tutorial for building clusters
• Font Rendering - UI text via FreeType
• Entity Component System - Powered via EnTT
• Physics Simulation - Rigid body dynamics and collision detection via Bullet3
• 3D Audio - Spatial audio with distance attenuation via miniaudio
• Model Loading - OBJ, FBX, and GLTF support via Assimp
• Event System - Keyboard, mouse, and window events with polling

Built With StrikeEngine

SpaceRacer

A fast-paced endless space racing game built entirely on StrikeEngine. Fly through procedurally generated asteroid fields, collect coins, and survive as long as possible - while obstacles pulse and grow in real-time to the beat of the soundtrack.

Inspirations

StrikeEngine's architecture and API design were inspired by:

• PlayCanvas - Entity hierarchy management
• Unity - Component-based entity model, script lifecycle ( onStart, onUpdate, onDestroy)
• Hazel - Application lifecycle, event system design, and logging architecture, based on the Hazel game engine tutorial series by TheCherno
