Entity Component System (ECS)

PlayCanvas uses an Entity Component System (ECS) to organize and manage the objects in your application.
In this design pattern:

• Entities are containers — they hold components but have no behavior of their own.
• Components add functionality or data to an Entity.
• Systems manage all instances of a given Component type.

This approach provides:

• Flexibility — you can mix and match components to build complex behaviors.
• Modularity — logic is encapsulated within components.
• Performance — systems process components in efficient batches.
