Simple Adobe Animate CC Actions Script 3.0 Project

I need a project done for my first year university project. The most important parts of this project are to follow all instructions that Im sending and use the ready script which I will also send (but script will probably need some little changes or replacing old names and variables with mine so it all fits together) Also, it would be great if you can include explanation of steps you have done. Unfortunately I couldn't include all necessary files right in here, but I will send 2 video clips once we start working together. Project needs to be done using Adobe Animate CC and Action Script 3.0
