the object this component is attached to. Note that this is a threejs Object3D with some additional features
the unique identifier for this component
Optional sourceholds the source identifier this object was created with/from (e.g. if it was part of a glTF file the sourceId holds the url to the glTF)
true if the object is enabled and active in the hierarchy
true if this component was destroyed (this.destroy()) or the whole object this component was part of
the layer of the gameObject this component is attached to
the name of the gameObject this component is attached to
shorthand for this.context.scene
the scene of the context
Is the gameObject marked as static
the tag of the gameObject this component is attached to

Optional supportsXROptional callback, you can implement this to only get callbacks for VR or AR sessions if necessary.
true if the mode is supported (if false the mode is not supported by this component and it will not receive XR callbacks for this mode)
Optional updateGenerated using TypeDoc
Needle Engine component base class. Component's are the main building blocks of the Needle Engine.
Derive from Behaviour to implement your own using the provided lifecycle methods.
Components can be added to threejs objects using
{@link addComponent}or{@link GameObject.addComponent}The most common lifecycle methods are
awake,start,onEnable,onDisableupdateandonDestroy.XR specific callbacks include
onEnterXR,onLeaveXR,onUpdateXR,onControllerAddedandonControllerRemoved.To receive pointer events implement
onPointerDown,onPointerUp,onPointerEnter,onPointerExitandonPointerMove.Example
