Detailed Description

This is a scene graph node to arbitrary render orders

One of the drawbacks of a scene graph is that it must always render with a pre-order traversal. This is the natural traversal for UI elements, but it is not convenient for character animation (where child components may need to be layered differently).

This node is introduced to solve this problem. For the most part, this node operates just like SceneNode. However, it allows you to resort the render order of the descendents of this node. Simply choose any one of the OrderedNode#Order values available. These orders are applied to the SceneNode#getPriority value of each node in the scene graph.

Any order other than a pre-order traversal comes as a cost, as we must cache the scene graph transform and color context of each node (these values are computed naturally from the recursive calls of a pre-order traversal). In addition, we must call std::sort (currently IntroSort) on all of the descendants every single render pass. However, as long as the number of children of this node is reasonably sized, this should not be an issue.

An OrderedNode is a render barrier. This means that if one OrderedNode (the first node) is a descendant of another OrderedNode (the second node), the first node will be rendered as a unit with the priority of that node. So it is impossible to interleave other descendants of the second node with descendants of the first node. This is necessary as the two OrderedNodes may have incompatible orderings.

Member Enumeration Documentation

◆ Order

enum class cugl::scene2::OrderedNode::Order : int

strong

This enum represents the possible render orders.

The default render order is Order#PRE_ORDER. When this is set, this node will act like a normal SceneNode. Other orders will create a list of render contexts that will be sorted before rendering. This will incur additional overhead, particularly if the number of descendant nodes is large.

Enumerator
PRE_ORDER	Render the nodes with a pre-order traversal (DEFAULT) In a pre-order traversal, the parent is rendered first and then the children. Children are rendered in the order that they are stored in the node.
POST_ORDER	Render the nodes with a post-order traversal In a post-order traversal, the children are rendered first and then the parent. Children are rendered in the order that they are stored in the node.
ASCEND	Render the nodes in ascending order by priority Children with lower priorities will appear at the back of the scene. The algorithm for std::sort is an unstable sorting algorithm and does not handle ties well. Hence all ties are broken by the pre-order traveral value.
DESCEND	Render the nodes in descending order by priority Children with higher priorities will appear at the back of the scene. The algorithm for std::sort is an unstable sorting algorithm and does not handle ties well. Hence all ties are broken by the pre-order traveral value.
PRE_ASCEND	Render the nodes in a pre-order traversal, sorted on ascending priority This order is still a pre-order traversal where the parent is rendered first and then the children. However, children are sorted with respect to their priority. Children with the lowest priority are drawn first.
PRE_DESCEND	Render the nodes in a pre-order traversal, sorted on descending priority This order is still a pre-order traversal where the parent is rendered first and then the children. However, children are sorted with respect to their priority. Children with the highest priority are drawn first.
POST_ASCEND	Render the nodes in a post-order traversal, sorted on ascending priority This order is still a pre-order traversal where the children are rendered first and then the parent. However, children are sorted with respect to their priority. Children with the lowest priority are drawn first.
POST_DESCEND	Render the nodes in a post-order traversal, sorted on descending priority This order is still a pre-order traversal where the children are rendered first and then the parent. However, children are sorted with respect to their priority. Children with the highest priority are drawn first.

Constructor & Destructor Documentation

◆ OrderedNode()

cugl::scene2::OrderedNode::OrderedNode ( )

Creates an uninitialized ordered node.

You must initialize this OrderedNode before use.

NEVER USE A CONSTRUCTOR WITH NEW. If you want to allocate a OrderedNode on the heap, use one of the static constructors instead.

◆ ~OrderedNode()

cugl::scene2::OrderedNode::~OrderedNode ( )

inline

Deletes this node, disposing all resources

Member Function Documentation

◆ alloc()

static std::shared_ptr< SceneNode > cugl::scene2::OrderedNode::alloc ( )

inlinestatic

Returns a newly allocated ordered node at the world origin.

The node has both position and size (0,0).

The node will use a pre-order traversal, unless the order is changed with setOrder.

Returns: a newly allocated ordered node at the world origin.

◆ allocWithBounds() [1/4]

static std::shared_ptr< SceneNode > cugl::scene2::OrderedNode::allocWithBounds ( const Rect rect )

inlinestatic

Returns a newly allocated ordered node with the given bounds.

The rectangle origin is the bottom left corner of the node in parent space, and corresponds to the origin of the Node space. The size defines its content width and height in node space. The node anchor is placed in the bottom left corner.

	)

inlinestatic

Returns a newly allocated ordered node with the given JSON specificaton.

This initializer is designed to receive the "data" object from the JSON passed to Scene2Loader. This JSON format supports all of the attribute values of its parent class. In addition, it supports the following additional attributes:

 "order":    The sort order of this node.

Sort orders are specified as lower case strings representing the names of the enum with dashes in place of underscores (e.g. "pre-order", "post-ascend"). All attributes are optional. There are no required attributes.

loader	The scene loader passing this JSON file
data	The JSON object specifying the node

Returns: a newly allocated ordered node with the given JSON specificaton.

◆ allocWithOrder() [1/3]

static std::shared_ptr< OrderedNode > cugl::scene2::OrderedNode::allocWithOrder ( Order order )

static std::shared_ptr< OrderedNode > cugl::scene2::OrderedNode::allocWithOrder	(	Order	order,
		Rect	bounds
	)

inlinestatic

Returns a newly allocated ordered node with the given bounds.

The rectangle origin is the bottom left corner of the node in parent space, and corresponds to the origin of the Node space. The size defines its content width and height. The node is anchored in the center and has position origin-(width/2,height/2) in parent space.

◆ CU_DISALLOW_COPY_AND_ASSIGN()

cugl::scene2::OrderedNode::CU_DISALLOW_COPY_AND_ASSIGN ( OrderedNode )

This macro disables the copy constructor (not allowed on scene graphs)

◆ dispose()

virtual void cugl::scene2::OrderedNode::dispose ( )

overridevirtual

Disposes all of the resources used by this node.

A disposed OrderedNode can be safely reinitialized. Any children owned by this node will be released. They will be deleted if no other object owns them.

Reimplemented from cugl::scene2::SceneNode.

◆ getOrder()

Order cugl::scene2::OrderedNode::getOrder ( ) const

inline

Returns the render order of this node

This render order will be applied to all descendants of this node. However, other instances of OrderedNode constitute a render boundary. While the ordered nodes themselves will be resorted, their children will not.

The default value of Order#PRE_ORDER will default to the normal render algorithm and is therefore the most efficient.

Returns: the render order of this node

◆ initWithData()

virtual bool cugl::scene2::OrderedNode::initWithData	(	const Scene2Loader *	loader,
		const std::shared_ptr< JsonValue > &	data

This initializer is designed to receive the "data" object from the JSON passed to Scene2Loader. This JSON format supports all of the attribute values of its parent class. In addition, it supports the following additional attributes:

 "order":    The sort order of this node.

Sort orders are specified as lower case strings representing the names of the enum with dashes in place of underscores (e.g. "pre-order", "post-ascend"). All attributes are optional. There are no required attributes.

Parameters

loader	The scene loader passing this JSON file

bool cugl::scene2::OrderedNode::initWithOrder	(	Order	order,
		Rect	bounds
	)

Initializes an ordered node with the given bounds.

The rectangle origin is the bottom left corner of the node in parent space, and corresponds to the origin of the Node space. The size defines its content width and height. The node is anchored in the center and has position origin-(width/2,height/2) in parent space.

Because the bounding box is explicit, this is the preferred initializer for Nodes that will explicitly contain other Nodes.

Parameters

order	The render order
bounds	The bounds of the node in parent space

Returns: true if initialization was successful.

◆ initWithOrder() [3/3]

bool cugl::scene2::OrderedNode::initWithOrder	(	Order	order,

◆ render() [1/2]

virtual void cugl::scene2::OrderedNode::render ( const std::shared_ptr< SpriteBatch > & batch )

inlineoverridevirtual

Draws this node and all of its children with the given SpriteBatch.

By default, this will revert to the render method of SceneNode. However if the order is anything other than Order#PRE_ORDER, it will construct a render queue of all children. This render queue will bypass all calls to SceneNode#render and instead call SceneNode#draw. This is why it is important for all custom subclasses of SceneNode to override draw instead of render.

Parameters

batch The SpriteBatch to draw with.

Reimplemented from cugl::scene2::SceneNode.

◆ render() [2/2]

void cugl::scene2::OrderedNode::render	(	const std::shared_ptr< SpriteBatch > &	batch,
		const Affine2 &	transform,
		Color4	tint
	)

overridevirtual

Draws this node and all of its children with the given SpriteBatch.

By default, this will revert to the render method of SceneNode. However if the order is anything other than Order#PRE_ORDER, it will construct a render queue of all children. This render queue will bypass all calls to SceneNode#render and instead call SceneNode#draw. This is why it is important for all custom subclasses of SceneNode to override draw instead of render.

Parameters

batch	The SpriteBatch to draw with.
transform	The global transformation matrix.
tint	The tint to blend with the node color.

Reimplemented from cugl::scene2::SceneNode.

◆ setOrder()

void cugl::scene2::OrderedNode::setOrder ( Order order )

inline

Sets the render order of this node

This render order will be applied to all descendants of this node. However, other instances of OrderedNode constitute a render boundary. While the ordered nodes themselves will be resorted, their children will not.

The default value of Order#PRE_ORDER will default to the normal render algorithm and is therefore the most efficient.

Parameters

order The render order of this node

◆ visit()

void cugl::scene2::OrderedNode::visit	(	const std::shared_ptr< SceneNode > &	node,
		const Affine2 &	transform,
		Color4	tint
	)

protected

Adds the given node ot the render queue.

This method replaces render to provide a delayed render command (via a queue of Context objects). This method is recursive. However, it will stop when it encounters any other OrderedNode objects.

Parameters

node	The descendant node to render.
transform	The global transformation matrix.
tint	The tint to blend with the node color.
