What you have to do is follow step by step the chap 3 of adobe animate cc (2021 release) book. At the end, you must get the same result as in the book.  you must submit to me an MPGE video, or a working. gif file (submission1) and your fla project from Adobe Animate. I have attached the chap 3: you need to zoom it to see well since it is a long screenshot. The two other attachment are the files you need to reproduce the chap 3. please again use adobe animate and not anything else.
