Constructor & Destructor Documentation

Layer()

Muto::Layer::Layer

(

const std::string &

name = "Layer"

)

Constructs a Layer with an optional name for debugging purposes.

Parameters

name	The name of the layer, used for debugging, defaulted to "Layer".

        : m_DebugName(name)
    {
    }

References m_DebugName.

~Layer()

Muto::Layer::~Layer ( )

virtual

    {
    }

Member Function Documentation

GetName()

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

inline

Retrieves the name of the layer for debugging purposes.

{ return m_DebugName; }

References m_DebugName.

OnAttach()

virtual void Muto::Layer::OnAttach ( )

inlinevirtual

Called when the layer is attached to the application.

Reimplemented in Muto::EditorLayer, Muto::ImGuiLayer, Muto::OpenGLImGuiLayer, and Sandbox2D.

{};

Referenced by Muto::Application::PushLayer(), and Muto::Application::PushOverlay().

OnDetach()

virtual void Muto::Layer::OnDetach ( )

inlinevirtual

Called when the layer is detached from the application.

Reimplemented in Muto::EditorLayer, Muto::ImGuiLayer, Muto::OpenGLImGuiLayer, and Sandbox2D.

{};

OnEvent()

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

inlinevirtual

Called when an event is dispatched to the layer.

Parameters

event

The event being dispatched.

Reimplemented in Muto::EditorLayer, Muto::ImGuiLayer, Muto::OpenGLImGuiLayer, Sandbox2D, ExampleLayer, and ExampleLayer.

{}

OnImGuiRender()

virtual void Muto::Layer::OnImGuiRender ( )

inlinevirtual

Called when the layer should render its ImGui components.

Reimplemented in Muto::EditorLayer, Muto::ImGuiLayer, Muto::OpenGLImGuiLayer, Sandbox2D, ExampleLayer, and ExampleLayer.

{};

OnRender()

virtual void Muto::Layer::OnRender ( )

inlinevirtual

Called when the layer should render its contents.

Note

Layers are responsible for their own rendering needs.

Todo:

add layer rendering into the application's render loop

{};

OnUpdate()

virtual void Muto::Layer::OnUpdate ( Timestep  ts )

inlinevirtual

Called every frame to update the layer with the given timestep.

Parameters

ts	The timestep representing the time elapsed since the last update.

Reimplemented in Sandbox2D, ExampleLayer, ExampleLayer, and Muto::EditorLayer.

{};
