Functionalities

For the moment, only two functionalities are available for the GretaUnity project, but many more are to come. GretaUnity communicates with Greta through the Thrift framework, so that if Greta plays any BML, FML or sound, it is reproduced in Unity.

Animation from file

By using the Animation Command Tester script, you can send a relative path to a BML or FML file to Greta, press T, and your file will automatically be played.

Object and gaze follower

By using the Greta Unity Object Tracker, you can track Unity objects' positions so that they are replicated in Greta, and continuously stare at a given object.
