Constructor & Destructor Documentation

SceneTree ( const SceneConfiguration & sceneConfiguration = {} )

Default constructor

Parameters

sceneConfiguration The configuration for the scene

SceneTree	(	const RenderingWindow &	renderingWindow,
		const SceneConfiguration &	sceneConfiguration = `{}`
	)

Constructor that attaches the scene tree to a rendering window

Parameters

renderingWindow	The window to attach to
sceneConfiguration	The configuration for the scene

~SceneTree ( )

override

Member Function Documentation

const std::shared_ptr<T>& addChild	(	const std::shared_ptr< T > &	child,
		const bool	async = `false`
	)

inline

Adds a child node to the scene tree

Template Parameters

T	The type of the child node

Parameters

child	The child node to add
async	Whether to add the child asynchronously

Returns: A reference to the added child

void attach ( const RenderingWindow & renderingWindow )

Attaches the scene tree to a rendering window

void attach ( const RenderTarget & renderTarget )

Attaches the scene tree to a render target

void detach ( )

Detaches the scene tree from its current render target & window

RenderingWindow& getRenderingWindow ( ) const

inline

Returns the rendering window the scene tree is attached to

RenderTarget& getRenderTarget ( ) const

inline

Returns the render target the scene tree is attached to

bool haveChild	(	const std::shared_ptr< T > &	child,
		const bool	recursive = `true`
	)		const

inline

Checks if the scene tree has a specific child node

Template Parameters

T	The type of the child node

Parameters

child	The child node to check for
recursive	Whether to search recursively

Returns: True if the child exists

Template Parameters

T	The type of the child node

Parameters

child	The child node to remove
async	Whether to remove the child asynchronously

Returns: True if the child was removed

void setCamera ( const lysa::Camera & camera )

Sets the camera for the scene tree

void setLuaThis ( )

override
