What are the differences between Actor Model and Entity-Component System?

What are the differences between Actor Model and Entity-Component System?

The Actor Model is a concurrency model where 'actors' are the fundamental units of computation, while the Entity-Component System (ECS) is an architectural pattern used in game development that focuses on composition over inheritance.

Can you explain how each model handles state?

In the Actor Model, each actor maintains its own state and communicates with other actors through message passing. In ECS, state is managed through components that are attached to entities, allowing for more flexible and modular design.

Which model is better for game development?

It depends on the game's requirements. ECS is often preferred for its flexibility and performance in managing game entities, while the Actor Model can be beneficial for handling complex interactions in distributed systems.

Are there any games that use these models?

Yes, many games use ECS, like Unity and Unreal Engine. The Actor Model is used in games that require distributed systems, such as multiplayer online games.
