ISystems is an interface for all systems within the ECS architecture. Each system must inherit from this interface and implement a specific method.

Allows systems to manipulate entities and their components using a defined operator, in order to execute the logic specific to each system (e.g., movement management, collision handling, etc.).

namespace ecs {
    namespace systems {
        class ISystems {
          public:
            virtual void operator()(Registry &, std::shared_ptr<IContext> ctx) = 0;
        };
    }; // namespace systems
}; // namespace ecs

Method: operator()

• Purpose:

  Applies the system’s logic to the entities managed by the Registry Class.

• Parameters:

  • Registry: The registry containing all entities and their associated components.
  • IContext: A shared global context between multiple systems, often used to store global data or shared states.

• Expected Behavior:

  • Each implementation of ISystems must define this method to update or manipulate entities based on the specific needs of the system.
  • This method is called on each game cycle, allowing systems to execute their logic continuously.
