Class GKComponentSystem<_ComponentType>

  • All Implemented Interfaces:
    NSFastEnumeration, NSObject
    public class GKComponentSystem<_ComponentType>
extends NSObject
implements NSFastEnumeration
    A component system is a homogeneous collection of components that are intended to be called at the same time. The system is homogeneous, meaning it only allows members of the same class into the system.

      • addComponent

        public void addComponent​(GKComponent component)
        Adds a component to the system. The component must be of the same class as the system's componentClass. The component is added to the tail of the collection and will be processed after components that were added before it.
        Throws:
        NSInvalidArgumentException - if the component added is not a kind of the system's componentClass.

      • addComponentWithEntity

        public void addComponentWithEntity​(GKEntity entity)
        Adds the supported component from the entity's component collection. This is conceptually the same as the pseudo-code: for (GKComponent *component in entity.components) if (component.class == system.componentClass) [system addComponent:component]
        See Also:
        GKEntity.components

      • classForGenericArgumentAtIndex

        public org.moe.natj.objc.Class classForGenericArgumentAtIndex​(long index)
        Returns the class of the specified generic index

      • componentClass

        public org.moe.natj.objc.Class componentClass()
        The collection's component class. Any selector the component supports can be called on the system and it will be forwarded to each of the components in the collection.

      • components

        public NSArray<? extends GKComponent> components()
        The array of components currently in the system.

      • countByEnumeratingWithStateObjectsCount

        public long countByEnumeratingWithStateObjectsCount​(org.moe.natj.general.ptr.VoidPtr state,

                                                    long len)
        Specified by:
        countByEnumeratingWithStateObjectsCount in interface NSFastEnumeration

      • initWithComponentClass

        public GKComponentSystem<?> initWithComponentClass​(org.moe.natj.objc.Class cls)
        Initializes a system for the given component class. The receiver can now only accept components of the given class.

      • objectAtIndexedSubscript

        public GKComponent objectAtIndexedSubscript​(long idx)
        Supports getting components via a [] subscript.

      • removeComponent

        public void removeComponent​(GKComponent component)
        Removes a component from the system Does nothing if the component is not in this system

      • removeComponentWithEntity

        public void removeComponentWithEntity​(GKEntity entity)
        Removes the supported component from the entity's component collection This is conceptually the same as the pseudo-code: for (GKComponent *component in entity.components) if (component.class == system.componentClass) [system removeComponent:component]

      • updateWithDeltaTime

        public void updateWithDeltaTime​(double seconds)
        Updates each component with the given delta time since the last update. Each component thus performs its time based logic with a single message.
