Description

Runtime version of a Component. Adds behavior to an entity and allows for operations on a per frame basis. Override the init and update methods in derived classes Every runtime version of a component receives on construction the resource it was created from and the entity instance it belongs to.

Constructor & Destructor Documentation

ComponentInstance()

ComponentInstance	(	EntityInstance &	entity,
		Component &	resource
	)

Constructor

Parameters

entity	instance the entity this component instance belongs to
resource	the resource this component was created from

Member Function Documentation

getComponent() [1/2]

nap::Component* getComponent

(

)

const

Returns

the resource this component was created from

getComponent() [2/2]

T * getComponent

Returns

the resource this component was created from as type T This will return a nullptr if the component is not derived from T

getEntityInstance()

nap::EntityInstance* getEntityInstance

(

)

const

Returns

the entity this component belongs to

init() [1/2]

virtual bool init

Override this method to initialize the object after de-serialization. When called it is safe to assume that all dependencies have been resolved up to this point.

Parameters

errorState

should contain the error message when initialization fails.

Returns

if initialization succeeded or failed.

init() [2/2]

virtual bool init ( utility::ErrorState &  errorState )

virtual

Initializes this component based on it's resource.

Parameters

errorState

contains the error when initialization fails.

Returns

if initialization succeeded.
