Description
A group is the simplest type of node. A typical group has no special properties or methods and acts as a simple placeholder to which other nodes may be attached. Groups are used to organize complex data and move sets of nodes such as models as though they are one.
Components are slightly more complex in that they work together with the TimeContext object to provide an independent clock for an object or group of objects.
There are two types of object constructors for groups. The Library asset constructor creates a new instance of the object from a resource in the Anark Studio Library. The scripting object constructor creates an empty Group object. Objects created via scripting are not available to the Anark Studio interface, but they do appear in the finished project.
Library asset constructor syntax
var theGroup = new Group( "library://libraryAssetName" [, objectToAttachTo] );libraryAssetName- required — A String with the name of the asset in the Anark Studio Library from which to create this object.
objectToAttachTo- optional — The String name of the object to which the group will be attached. The group must be attached to an object in the scene either now or later in order to appear in the scene during playback.
Scripting object constructor syntax
var theGroup = new Group( [sceneGraphName] [, objectToAttachTo] );sceneGraphName- optional — A String with the name for the new group in the scene graph.
objectToAttachTo- optional — The String name of the object to which the group will be attached. The group must be attached to an object in the scene either now or later in order to appear in the scene during playback.
Group Examples
// Create a group.
this.manGroup = new Group( "BodyGroup" );
// Attach the group to an existing layer.
scene.BackgroundLayer.attach( this.manGroup );
// Attach some existing models to the group.
this.manGroup.attach( theHeadModel );
this.manGroup.attach( theTorsoModel );
this.manGroup.attach( theArmsModel );
this.manGroup.attach( theLegsModel );
// Move the entire group of objects.
this.manGroup.position.x = 100;
this.manGroup.position.y = 50;
