Public Methods

Method Defined By
Expand Node new Node () : cocos.nodes.Node <constructor>

Returns

 Node
Expand addChild addChild ({child:cocos.nodes.Node,[z:Integer],[tag:Integer/String]}) : cocos.nodes.Node
Add a child Node

Named Arguments

  • child : cocos.nodes.Node
    The child node to add
  • z : Integer (Optional)
    Z Index for the child
  • tag : Integer/String (Optional)
    A tag to reference the child with

Returns

 Node
Expand bindTo bindTo (key:String,target:BOject,[targetKey:String],[noNotify:Boolean]) : void
Bind the value of a property on this object to that of another object so they always have the same value. Setting the value on either object will update the other too.

Arguments

  1. key : String
    Name of the property on this object that should be bound
  2. target : BOject
    Object to bind to
  3. targetKey : String (Optional)
    Key on the target object to bind to
  4. noNotify : Boolean (Optional)
    Set to true to prevent this object's property triggering a 'changed' event when adding the binding

Returns

  • void
 BObject
Expand changed changed (key:*) : void

Arguments

  1. key :

Returns

  • void

Expand cleanup cleanup () : void

Returns

  • void
 Node
Expand convertToNodeSpace convertToNodeSpace (worldPoint:*) : void

Arguments

  1. worldPoint :

Returns

  • void
 Node
Expand detatchChild detatchChild (opts:*) : void

Arguments

  1. opts :

Returns

  • void
 Node
Expand draw draw (context:CanvasRenderingContext2D/WebGLRenderingContext,rect:geometry.Rect) : void
Draws the node. Override to do custom drawing. If it's less efficient to draw only the area inside the rect then don't bother. The result will be clipped to that area anyway.

Arguments

  1. context : CanvasRenderingContext2D/WebGLRenderingContext
    Canvas rendering context
  2. rect : geometry.Rect
    Rectangular region that needs redrawing. Limit drawing to this area only if it's more efficient to do so.

Returns

  • void
 Node
Expand get get (key:String) : *
Get a property from the object. Always use this instead of trying to access the property directly. This will ensure all bindings, setters and getters work correctly.

Arguments

  1. key : String
    Name of property to get or dot (.) separated path to a property

Returns

  • *
    Value of the property

 Node
Expand schedule schedule ({method:String/Function,[interval:Float]}) : void
Schedules a custom method with an interval time in seconds. If time is 0 it will be ticked every frame. If time is 0, it is recommended to use 'scheduleUpdate' instead. If the method is already scheduled, then the interval parameter will be updated without scheduling it again.

Named Arguments

  • method : String/Function
    Function of method name to schedule
  • interval : Float (Optional)
    Interval in seconds

Returns

  • void
 Node
Expand scheduleUpdate scheduleUpdate (opts:*) : void

Arguments

Returns

  • void
 Node
Expand set set (key:String,value:*) : void

  2. value : *
    New value for the property

Returns

  • void
 BObject
Expand setValues setValues (kvp:Object) : void
