Detailed Description

Handles entities that should not be duplicated.

Constructor & Destructor Documentation

DoNotDuplicateSystem()

DoNotDuplicateSystem ( bool setSingleton = true )

protected

Creates a new do not duplicate system instance.

Parameters

setSingleton

set system singleton instance

Member Function Documentation

getComponentName()

const std::string & getComponentName ( ) const

overrideprotectedvirtual

Returns specific component name of the system.

Reimplemented from ComponentSystem< DoNotDuplicateComponent, false >.

createComponent()

ID< Component > createComponent ( ID< Entity > entity )

inlineoverrideprotectedvirtualinherited

Creates a new component instance for the entity.

You should use Manager to add components to the entity.

Reimplemented from System.

destroyComponent()

void destroyComponent ( ID< Component > instance )

inlineoverrideprotectedvirtualinherited

Destroys component instance.

You should use Manager to remove components from the entity.

Reimplemented from System.

copyComponent()

void copyComponent ( View< Component > source, View< Component > destination )

inlineoverrideprotectedvirtualinherited

Copies component data from source to destination.

You should use Manager to copy component data of entities.

Reimplemented from System.

getComponentType()

std::type_index getComponentType ( ) const

inlineoverridevirtualinherited

Returns specific component typeid() of the system.

Note

Override it to define a custom component of the system.

Reimplemented from System.

getComponent() [1/2]

View< Component > getComponent ( ID< Component > instance )

inlineoverridevirtualinherited

Returns specific component View.

Reimplemented from System.

getComponent() [2/2]

View< DoNotDuplicateComponent > getComponent ( ID< Entity > entity ) const

inlineinherited

Returns entity specific component view.

Parameters

entity

target entity with component

Note

This function is faster than the Manager one.

disposeComponents()

void disposeComponents ( )

inlineoverridevirtualinherited

Actually destroys system components.

Components are not destroyed immediately, only after the dispose call.

Reimplemented from System.

hasComponent()

bool hasComponent ( ID< Entity > entity ) const

inlineinherited

Returns true if entity has specific component.

Parameters

entity

target entity with component

Note

This function is faster than the Manager one.

tryGetComponent()

View< DoNotDuplicateComponent > tryGetComponent ( ID< Entity > entity ) const

inlineinherited

Returns entity specific component view if exist.

Parameters

entity

target entity with component

Note

This function is faster than the Manager one.
