I am trying to use lens studio and listen for the MouthOpened event. Here is what I have:

script.createEvent("MouthOpenedEvent");

event.faceIndex = 0;

event.bind(function (eventData)

{

print("Mouth was opened on face 0");

});

On Mouth Opened I want to know the position of the mouth so that I can do other checks e.g. see if another object is in that position. So I would like to get the approx position of the mouth (say a rectangle around it). Is there a way to get this e.g. from eventData?

If not is there a different way to achieve what I am doing.

Thanks,

Sudhir

Hi Sudhir, to track the position of the mouth, I'd use an object bound to the head and track its position. To do this:
- Create a new Head Binding object (Objects Panel -> Add New -> Head Binding)
- Select the Head Binding object and set the Attach to Point dropdown to Head Center
- Add a new Box (Objects Panel -> Add New -> Box) and make it a child of the Head Binding object so you can visually see where the point it (should be centered on the mouth)
- The head binding's position will now reflect where the mouth is in world space. Add the following script to the Head Binding object bound to the Frame Updated event to print out its world position
```
var currPosition = script.getTransform().getWorldPosition();
print( "Mouth position: (" + currPosition.x + ", " + currPosition.y + ", " + currPosition.z + ")" );
```
