Member Function Documentation

clear()

void Renderer::clear

(

)

const

Clears the rendering target with the drawing color. Clears the current rendering target with the drawing color set in the SDL renderer.

render()

void Renderer::render	(	const std::map< int, std::multimap< int, std::reference_wrapper< Renderable > > > &	objects,
		const Scene &	scene
	)

Renders a collection of game objects to the screen. Renders a given collection of game objects to the screen. Each game object is expected to have its own sprite, or it will be skipped.

Mind that this method clears the entire screen and renders immediately on finish. If you want to batch multiple calls, fuse them into one.

Parameters

objects	A map of renderable objects grouped by their rendering layer
scene	The current scene being rendered

vsync() [1/2]

bool Renderer::vsync

(

)

const

Checks if vertical synchronization (VSync) is enabled.

Returns

true if VSync is enabled, false otherwise.

vsync() [2/2]

void Renderer::vsync

(

bool

enabled

)

Toggles vertical synchronization (VSync) which limits fps to the monitor's refresh rate.

window()

Window & Renderer::window
