This Skill helps developers create ECS-based systems that process entities with required components, enabling consistent gameplay logic, AI, and movement updates within the engine.
Create a new file at game/system/<Name>.go implementing a <Name>System and register it in game/systems.go.

To create an ECS game system, implement a System interface with an Update(world, scene, dt) method, place the file under game/system/<Name>.go, and register it in game/systems.go to enable consistent per-frame processing.
The engine defines optional interfaces for game logic beyond standard updates: SystemWithInit, SystemWithRender, and SystemWithCleanup, allowing you to hook setup, rendering, and teardown phases into your systems.
Yes, ECS systems run consistently across editor and runtime modes. You can implement movement, AI, and other gameplay logic that updates every frame safely in both environments without modifying the core code.
To register a new system, add your custom System implementation to the game/systems.go file. This ensures the engine queries and executes your component-based gameplay logic during the frame update loop.
Yes, the engine-system approach uses Donburi for its ECS architecture. Systems query for entities with necessary components using the world state, enabling decoupled gameplay logic updates every frame.
Use SystemWithCleanup when your system allocates resources or state that must be explicitly released. The standard System interface only handles per-frame updates, while cleanup ensures safe teardown.
