ECS Game Engine

https://github.com/omonnin-ynov/MyGameEngine

A Game Engine in C++20 supporting a simplified ECS, written in a few weeks.

To download the engine, clone the github repo. The download on this page contains a sample game that's a vampire survivors clone and pretty stable memory usage.

Features:

• Simplified ECS
• Engine management through Application class
• 2D SFML Integration
• Starting up an SFML Window
• Views with CameraComponent
• Automatic call of drawable components in update loop, scale with parent entity scale
• SpriteRendererComponent with a texture and sprite
• Input checking in Update in PlayerInput
• Box2D integration :
  • Instantiate a b2World
  • Synchronize physics world and graphical world in the update loop
  • RigidBodyComponent, ColliderComponent wrap b2Body and b2Fixture
  • Contact wrapper with ICollidable and CollisionListener
  • Collision filtering
• YAML integration
• Resource path manager
• Can add player characters, projectiles and enemies purely through config file
• Lua script integration with globally accessible lua_state to save on reloading scripts

Features I'd like to add:

• Components can have children components
• ECS paradigm with memory accesses optimized for locality
• Sprite center matches up with b2Body center
• Better input integration
• GUI Components
• Sound
• Tilemap manager
