Detailed Description

Manages execution and order of systems.

Systems are updated and rendered in order. Lower priority values go first. Systems update and render before scenes.

Member Function Documentation

AddSystem()

template<typename T , typename... Args>
requires std::is_base_of_v<System, T>

T & SystemManager::AddSystem ( const u32  priority = 1, Args &&...  args  )

inline

Adds a system to the manager.

The system is constructed in within the manager and owned by it. Systems must derive from the System base class..

Template Parameters

T	System type
Args	T Constructor argument types

Parameters

priority	Execution priority (lower executes first)
args	System constructor arguments

Returns

Reference to the created system

Usage:

PhysicsSystem& physics = systemManager.AddSystem<PhysicsSystem>(3, gravity);

GetSystem()

template<typename T >
requires std::is_base_of_v<System, T>

T * SystemManager::GetSystem ( )

inline

Gets a system pointer.

Return a nullptr if the system does not exist.

Template Parameters

T	System type

Update()

void SystemManager::Update

(

const float

deltaT

)

Updates all systems in order.

Parameters

deltaT
