Detailed Description

Base class of all Karma's Layers. For instance KarmaGuiLayer.

Constructor & Destructor Documentation

Layer()

Karma::Layer::Layer

(

const std::string &

name = "Layer"

)

A constructor.

Since

Karma 1.0.0

~Layer()

Karma::Layer::~Layer ( )

virtual

A destructor.

Since

Karma 1.0.0

Member Function Documentation

GetName()

const std::string & Karma::Layer::GetName ( ) const

inline

Getter for the name of the Layer (debugging purposes).

Since

Karma 1.0.0

KarmaGuiRender()

virtual void Karma::Layer::KarmaGuiRender ( float deltaTime )

pure virtual

Function called in each game loop, specifically for rendering purposes.

This is part of KarmaGui rendering sequence, thus different from OnUpdate().

See also

Application::Run()

Since

Karma 1.0.0

Implemented in Karma::KarmaGuiLayer.

OnAttach()

virtual void Karma::Layer::OnAttach ( )

pure virtual

A function called on Layer when the Layer is pushed or OverLay is pushed.

See also

Application::PushLayer, Application::PushOverlay

Since

Karma 1.0.0

Implemented in Karma::KarmaGuiLayer.

OnDetach()

virtual void Karma::Layer::OnDetach ( )

pure virtual

A function called on Layer when the LayerStack is destroyed.

See also

LayerStack::~LayerStack()

Since

Karma 1.0.0

Implemented in Karma::KarmaGuiLayer.

OnEvent()

virtual void Karma::Layer::OnEvent ( Event & event )

inlinevirtual

For dispatching Events specific to the Layer.

Note

GLFW calls the Application::OnEvent which further calls the OnEvent function in the subsequent layers and, depending on m_Handled, the depth of the call chain (measured in the sense of for-loop, upon the ordered layers) is determined.

Since

Karma 1.0.0

Reimplemented in Karma::KarmaGuiLayer.

OnUpdate()

virtual void Karma::Layer::OnUpdate ( float deltaTime )

pure virtual

Function called in each game loop.

Parameters

deltaTime

The time step (or interval) gap between two consecutive calls (previous single loop iteration time)

See also

Application::Run()

Since

Karma 1.0.0

Implemented in Karma::KarmaGuiLayer.
