Class Detail

cc.SpriteBatchNode()

In Canvas render mode ,cc.SpriteBatchNodeCanvas is like a normal node: if it contains children.
If its _useCache is set to true, it can cache the result that all children of SpriteBatchNode to a canvas
(often known as "batch draw").

A cc.SpriteBatchNode can reference one and only one texture (one image file, one texture atlas).
Only the cc.Sprites that are contained in that texture can be added to the cc.SpriteBatchNode.
All cc.Sprites added to a cc.SpriteBatchNode are drawn in one WebGL draw call.
If the cc.Sprites are not added to a cc.SpriteBatchNode then an WebGL draw call will be needed for each one, which is less efficient.

Limitations:
- The only object that is accepted as child (or grandchild, grand-grandchild, etc...) is cc.Sprite or any subclass of cc.Sprite.
eg: particles, labels and layer can't be added to a cc.SpriteBatchNode.
- Either all its children are Aliased or Antialiased. It can't be a mix.
This is because "alias" is a property of the texture, and all the sprites share the same texture. 

//create a SpriteBatchNode
var parent2 = cc.SpriteBatchNode.create("res/animations/grossini.png", 50);

Field Detail

addChild
add child to cc.SpriteBatchNode (override addChild of cc.Node)
appendChild
addChild helper, faster than insertChild
ctor
Constructor
draw
draw cc.SpriteBatchNode (override draw of cc.Node)
{cc.Texture2D|HTMLImageElement|HTMLCanvasElement} getTexture
Return texture of cc.SpriteBatchNode
{Boolean} initWithTexture

initializes a CCSpriteBatchNode with a texture2d and capacity of children.
The capacity will be increased in 33% in runtime if it run out of space.

insertQuadFromSprite

Inserts a quad at a certain index into the texture atlas. The cc.Sprite won't be added into the children array.
This method should be called only when you are dealing with very big AtlasSprite and when most of the cc.Sprite won't be updated.
For example: a tile map (cc.TMXMap) or a label with lots of characters (cc.LabelBMFont)

removeAllChildren

Removes all children from the container and do a cleanup all running actions depending on the cleanup parameter.
(override removeAllChildren of cc.Node)

removeSpriteFromAtlas
remove sprite from TextureAtlas
setTexture
texture of cc.SpriteBatchNode setter
updateQuadFromSprite

Updates a quad at a certain index into the texture atlas. The CCSprite won't be added into the children array.
This method should be called only when you are dealing with very big AtlasSrite and when most of the cc.Sprite won't be updated.
For example: a tile map (cc.TMXMap) or a label with lots of characters (BitmapFontAtlas)

visit
don't call visit on it's children ( override visit of cc.Node )

Method Detail

  • {cc.SpriteBatchNode} addSpriteWithoutQuad(child, z, aTag)

    This is the opposite of "addQuadFromSprite.
    It add the sprite to the children and descendants array, but it doesn't update add it to the texture atlas

    Parameters:
    {cc.Sprite} child
    {Number} z
    zOrder
    {Number} aTag
    Returns:
    {cc.SpriteBatchNode}
  • {Number} atlasIndexForChild(sprite, nZ)
    get atlas index for child
    Parameters:
    {cc.Sprite} sprite
    {Number} nZ
    Returns:
    {Number}
  • <static> {cc.SpriteBatchNode} cc.SpriteBatchNode.create(fileImage, capacity)

    creates a cc.SpriteBatchNodeCanvas with a file image (.png, .jpg etc) with a default capacity of 29 children.
    The capacity will be increased in 33% in runtime if it run out of space.
    The file will be loaded using the TextureMgr.

    //create a SpriteBatchNode
var parent2 = cc.SpriteBatchNode.create("res/animations/grossini.png", 50);
    Parameters:
    {String} fileImage
    {Number} capacity
    Returns:
    {cc.SpriteBatchNode}
  • <static> {cc.SpriteBatchNode} cc.SpriteBatchNode.createWithTexture(texture, capacity)

    creates a cc.SpriteBatchNodeCanvas with a texture2d and a default capacity of 29 children.
    The capacity will be increased in 33% in runtime if it run out of space.

    Parameters:
    {cc.Texture2D} texture
    {Number} capacity
    Returns:
    {cc.SpriteBatchNode}
  • {cc.BlendFunc} getBlendFunc()
    returns the blending function used for the texture
    Returns:
    {cc.BlendFunc}
  • {Array} getDescendants()
    Return Descendants of cc.SpriteBatchNode
    Returns:
    {Array}
  • {cc.TextureAtlas} getTextureAtlas()
    Return TextureAtlas of cc.SpriteBatchNode
    Returns:
    {cc.TextureAtlas}
  • {Number} highestAtlasIndexInChild(sprite)
    get highest atlas index in child
    Parameters:
    {cc.Sprite} sprite
    Returns:
    {Number}
  • increaseAtlasCapacity()
    increase Atlas Capacity
  • {Boolean} init(fileImage, capacity)

    initializes a cc.SpriteBatchNode with a file image (.png, .jpeg, .pvr, etc) and a capacity of children.
    The capacity will be increased in 33% in runtime if it run out of space.
    The file will be loaded using the TextureMgr.

    Parameters:
    {String} fileImage
    {Number} capacity
