First I want to say sorry that I hand in this assignment late. However, I really have too many problems with Unity this time. I was going to make a large village with fancy houses, markets, and farm fields, however, I lost everything when I tried to delete one of the "C# errors". Unity was forced to quit and I was not able to reopen my file. I still don't get what happened now but I really want to tell any of you guys reading this article that, NEVER EVER TRY TO DELETE ANY UNKNOWN SCRIPTS IN UNITY. Late in night I downloaded Unity by myself and did a much simpler one with box opening&closing and butterfly flying at the same time, that's the trigger box of the treasure box which controls both the treasure box and the butterfly. I also add the sound of flapping wings onto the butterfly so we can hear the sound when we approach to the butterfly. This time was really tough, I hope my following works would be better. 🙂

BTW, I really need a way to fix my old files because I really love my village QAQ
