Parameters:
Name Type Argument Description
texture Texture

The texture to use
vertices Float32Array <optional>

if you want to specify the vertices
uvs Float32Array <optional>

if you want to specify the uvs
indices Uint16Array <optional>

if you want to specify the indices
drawMode number <optional>

the drawMode, can be any of the Mesh.DRAW_MODES consts
Source:

Extends

Members

<static, constant> DRAW_MODES

Different drawing buffer modes supported

Properties:
Name Type Description
DRAW_MODES object

Name Type Description
TRIANGLE_MESH number
TRIANGLES number
Source:

alpha :Number

The opacity of the node.

Type:
Inherited From:
Source:

cacheAsBitmap :boolean

Set this to true if you want this display object to be cached as a bitmap.
This basically takes a snap shot of the display object as it is at that moment. It can provide a performance benefit for complex static displayObjects.
To remove simply set this property to 'false'

Type:
  • boolean
Inherited From:
Source:

<readonly> children :Array.<Node>

The list of children added to this node.

Type:
Inherited From:
Source:

filterArea :Rectangle

The area the filter is applied to. This is used as more of an optimisation
rather than figuring out the dimensions of the node each frame you can set this rectangle

Type:
Inherited From:
Source:

filters :Array.<AbstractFilter>

Sets the filters for this Node.

  • IMPORTANT: This is a WebGL only feature and will be ignored by the canvas renderer.
    To remove filters simply set this property to 'null'
Type:
Inherited From:
Source:

height :Number

The height of the Node, setting this will actually modify the scale to achieve the value set

Type:
Inherited From:
Source:

mask :Graphics|Sprite

Sets a mask for this Node. A mask is an object that limits the visibility of an object to the shape of the mask applied to it.
A regular mask must be a Graphics or a Sprite object. This allows for much faster masking in canvas as it utilises shape clipping.
To remove a mask, set this property to null.

Type:
Inherited From:
Source:
To Do:
  • For the moment, CanvasRenderer doesn't support Sprite as mask.

<readonly> parent :Node

The node that contains this one.

Type:
Inherited From:
Source:

pivot :Vector

The pivot point of the node that it rotates around

Type:
Inherited From:
Source:

position :Vector

The coordinate of the node relative to the local coordinates of the parent.

Type:
Inherited From:
Source:

renderable :Boolean

Can this node be rendered, if false the node will not be drawn but the updateTransform
methods will still be called.

Type:
  • Boolean
Inherited From:
Source:

rotation :Number

The rotation of the node in radians.

Type:
Inherited From:
Source:

scale :Vector

The scale factor of the node.

Type:
Inherited From:
Source:

skew :Vector

The skew factor for the node in radians.

Type:
Inherited From:
Source:

system :SystemGfx

Sets the gfx system this node will be rendered with

Type:
Inherited From:
Source:

texture :Texture

The texture that the sprite is using

Type:
Source:

visible :Boolean

The visibility of the node. If false the node will not be drawn, and
the updateTransform function will not be called.

Type:
  • Boolean
Inherited From:
Source:

width :Number

The width of the Node, setting this will actually modify the scale to achieve the value set

Type:
Inherited From:
Source:

<readonly> worldAlpha :Number

The multiplied alpha of the node

Type:
Inherited From:
Source:

<readonly> worldTransform :Matrix

Current transform of the node based on world (parent) factors

Type:
Inherited From:
Source:

<readonly> worldVisible :Boolean

Indicates if this node is globally visible.

Type:
  • Boolean
Inherited From:
Source:

x :Number

The position of this Node on the x axis relative to the local coordinates of the parent.

Type:
Inherited From:
Source:

y :Number

The position of this Node on the y axis relative to the local coordinates of the parent.
