◆ cleanup()

void Cogs::Core::RenderSystem::cleanup ( Context * )

overridevirtual

Provided for custom cleanup logic in derived systems.

Cleanup is performed during shutdown of the system, and all entities and related data should have been deleted.

All system services are available during the execution of cleanup().

Reimplemented from Cogs::Core::ComponentSystemBase.

Definition at line 140 of file RenderSystem.cpp.

References Cogs::Core::Context::taskManager.

◆ createComponent()

ComponentHandle Cogs::Core::RenderSystem::createComponent ( )

overridevirtual

Create a new component instance.

Reimplemented from Cogs::Core::ComponentSystem< ComponentType >.

Definition at line 147 of file RenderSystem.cpp.

◆ destroyComponent()

void Cogs::Core::RenderSystem::destroyComponent ( ComponentHandle component )

overridevirtual

Destroy the component held by the given handle.

◆ initialize()

void Cogs::Core::RenderSystem::initialize ( Context * context )

overridevirtual

Initialize the system.

Initialization is performed after all systems are created and a renderer initialized, but before the first time anything is rendered.

Parameters

context Pointer to the context the system lives in.

◆ postUpdate()

void Cogs::Core::RenderSystem::postUpdate ( Context * )

overridevirtual

Overridden to propagate carry flags. Any subclass overriding this method should also call base class.

Reimplemented from Cogs::Core::ComponentSystem< ComponentType >.

Definition at line 133 of file RenderSystem.cpp.
