About

The system runs operations that must be performed on its assoiciated components.

Typically, this is expected to be run every frame, though this is not a strict requirement.

Examples of the system include the health_system; which reads the value of the entitie's health component and ensures h > 0.

void health_system(){
    for (i = 0; i < registeredComponents.size(); i++){
        if (registeredComponents[i].health <= 0){
            registeredComponents[i].dead = true;
            if (registeredComponents[i].isPlayer){
                GameOver();
            }
        }
    }
}

Implementation

The systems are managed by the following code:

class SystemManager{
    ECS baseECS;
    int systemIndex;

    public SystemManager(ECS baseECS){
        this.baseECS = baseECS;
        systemIndex = 0;
    }
}
