i want to use mouth opened event on every millisecond or on UpdateEvent

  • I don't think you would really want to create that many events. What are you trying to accomplish? Most likely you only need one mouth open and mouth closed event that interacts with whatever the update event is doing.

  • Hi Syed, 

    Brandon is right, it won't be good to bind an event on every update as it will make the lens really slow since the Lens will look for the user opening their mouth multiple times. 

    You usually want to bind it once like

    function() {print("mouth just opened");}

    Take a look at the API page for more examples: https://lensstudio.snapchat.com/api/classes/MouthOpenedEvent/

    If you'd like to track how wide the opening of the mouth is to drive something, take a look at this template: 


    Can't wait to see what you come up with!
