If the renderer should use instancing
If this is a boolean (true) all materials will be instanced or (false) none of them.
If this is an array of booleans the materials will be instanced based on the index of the material.
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 instancing handles
true if this renderer has instanced objects
the layer of the gameObject this component is attached to
set undefined to return to default lightmap
the name of the gameObject this component is attached to
shorthand for this.context.scene
the scene of the context
Get the mesh Object3D for this renderer
Warn: if this is a multimaterial object it will return the first mesh only
a mesh object3D.
Get all the mesh Object3D for this renderer
an array of mesh object3D.
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 updateStatic isCheck if an object is currently rendered using instancing
true if the object is rendered using instancing
Static setStatic setSet the rendering state only of an object (makes it visible or invisible) without affecting component state or child hierarchy visibility! You can also just enable/disable the Renderer component on that object for the same effect!
If you want to activate or deactivate a complete object you can use obj.visible as usual (it acts the same as setActive in Unity)
Generated 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
