explicit

Creates a new system manager,.

Parameters

entityManager

The entity manager to be used by systems

delete

~SystemManager()

CeresEngine::SystemManager::~SystemManager

(

)

Destroys the system manager.

Member Function Documentation

add()

template<CSystemImplementation S, typename... Args>

S & CeresEngine::SystemManager::add

(

Args &&...

args

)

Adds a new system of type S.

Template Parameters

S	the type of the system implementation
Args	the system constructor argument types

Parameters

args	The system constructor arguments

Returns

A reference to the created system

get()

template<CSystem S>

S & CeresEngine::SystemManager::get

(

)

Gets a system of type S.

Template Parameters

S	the type of the system to be retrieved

Returns

A reference to the system of type S.

has()

template<CSystem S>

bool CeresEngine::SystemManager::has ( )

noexcept

Checks if the manager contains a system of type S.

Template Parameters

S	the type of the system to be checked

Returns

True if the system contains a system of type S, false otherwise.

operator=()

SystemManager & CeresEngine::SystemManager::operator= ( const SystemManager &  )

delete

remove()

template<CSystem S>

void CeresEngine::SystemManager::remove

(

)

Removes a system of type S.

Template Parameters

S	the type of the system to be removed

sort()

void CeresEngine::SystemManager::sort ( )

privatenoexcept

Updates the system priority sorted list.

update() [1/2]

void CeresEngine::SystemManager::update

(

double

time

)

Updates all systems.

Dispatches a update(double) call to all systems.

Parameters

time	The time elapsed since the last update call.

update() [2/2]

template<CSystem S>

bool CeresEngine::SystemManager::update

(

double

time

)

Update a specific system of type S.

Dispatches a update(double) call only to the system of type S. If no such system type is present, this method does nothing.

Template Parameters

S	the type of the system to be updated

Parameters

time	The time elapsed since the last update call.

Returns

True if the system was present and updated, false otherwise.
