Methods

create

(
  • [cfg]
)

Inherited from Component: /home/lindsay/xeolabs/xeogl-next/xeogl/src/component.js:896

Convenience method for creating a Component within this Component's Scene.

The method is given a component configuration, like so:

var material = myComponent.create({
     type: "xeogl.PhongMaterial",
     diffuse: [1,0,0],
     specular: [1,1,0]
}, "myMaterial");

Parameters:

  • [cfg] optional

    Configuration for the component instance.

Returns:

:

destroy

()

Inherited from Component: /home/lindsay/xeolabs/xeogl-next/xeogl/src/component.js:1005

Destroys this component.

Fires a destroyed event on this Component.

Automatically disassociates this component from other components, causing them to fall back on any defaults that this component overrode on them.

TODO: describe effect with respect to #create

error

(
  • message
)

Inherited from Component: /home/lindsay/xeolabs/xeogl-next/xeogl/src/component.js:583

Logs an error for this component to the JavaScript console.

The console message will have this format: [ERROR] [<component type> =<component id>: <message>

Also fires the message as an error event on the parent Scene.

Parameters:

  • message String

    The message to log

fire

(
  • event
  • value
  • [forget=false]
)

Inherited from Component: /home/lindsay/xeolabs/xeogl-next/xeogl/src/component.js:407

Fires an event on this component.

Notifies existing subscribers to the event, optionally retains the event to give to any subsequent notifications on the event as they are made.

Parameters:

  • event String

    The event type name

  • value Object

    The event parameters

  • [forget=false] Boolean optional

    When true, does not retain for subsequent subscribers

hasSubs

(
  • event
)
Boolean

Inherited from Component: /home/lindsay/xeolabs/xeogl-next/xeogl/src/component.js:534

Returns true if there are any subscribers to the given event on this component.

Parameters:

  • event String

    The event

Returns:

Boolean:

True if there are any subscribers to the given event on this component.

isType

(
  • type
)
Boolean

Inherited from Component: /home/lindsay/xeolabs/xeogl-next/xeogl/src/component.js:371

Tests if this component is of the given type, or is a subclass of the given type.

The type may be given as either a string or a component constructor.

This method works by walking up the inheritance type chain, which this component provides in property Component/superTypes:property, returning true as soon as one of the type strings in the chain matches the given type, of false if none match.

Examples:

var myRotate = new xeogl.Rotate({ ... });

myRotate.isType(xeogl.Component); // Returns true for all xeogl components
myRotate.isType("xeogl.Component"); // Returns true for all xeogl components
myRotate.isType(xeogl.Rotate); // Returns true
myRotate.isType(xeogl.Transform); // Returns true
myRotate.isType("xeogl.Transform"); // Returns true
myRotate.isType(xeogl.Mesh); // Returns false, because xeogl.Rotate does not (even indirectly) extend xeogl.Mesh

Parameters:

  • type String | Function

    Component type to compare with, eg "xeogl.PhongMaterial", or a xeogl component constructor.

Returns:

Boolean:

True if this component is of given type or is subclass of the given type.

log

(
  • message
)

Inherited from Component: /home/lindsay/xeolabs/xeogl-next/xeogl/src/component.js:545

Also fires the message as a log event on the parent Scene.

Parameters:

  • message String

    The message to log

off

(
  • subId
)

Inherited from Component: /home/lindsay/xeolabs/xeogl-next/xeogl/src/component.js:488

  • callback
  • [scope=this]
)
String

Inherited from Component: /home/lindsay/xeolabs/xeogl-next/xeogl/src/component.js:446
