Welcome to the PolyEngine wiki!
PolyEngine is a C++ based, enthusiasts driven, multiplatform, low dependancy, 2D/3D games engine.
Engine architecture is centered around very strict ECS (Entity - Component - System) pattern, where:
- Entities are just component containers and are not visible outside the very core of the angine
- Components represent entity state and have no engine/gameplay logic. There are entity components and world components.
- World contains all entities with their components and world components that are currentely simulated by the engine. It serves simillar role to scene in other engines.
- Phases are essentially stateless systems, represented as functions that take world and perform update on it. Order in which phases are executed is explicit and unmutable. For example: rendering system iterates all mesh components in a given world and renders them to scene.
- All communication between systems is possible only through components state. There is no event mechanism anywhere in engine. This restriction, although very strict, provides a way to keep system logic decoupled.
