Although my barking box looks simple, I invested a great deal of time to get this to trigger properly. After realizing my open and close animations were not working because I had failed to check the Legacy option, I struggled with sound. Professor Pacheco and I realized the "Play Sound" was not functioning correctly with my version of Unity, and instead I needed to utilize the "Audio Play" action within my Playmaker events. Before, sounds were being cued prior to entering the trigger and those automated by the trigger were barely audible. Now, no sounds occur automatically and my sounds are certainly audible.
