[CHAOS] I NEED HELP!

[PutraenusAlivius]

Hey, guys. So i got a lot of sequences in my CS, A Forgotten Memory. But, i don't have the knowledge to do these things. Here they are;

1. I want area when i collide with it, i cant move (the Block box), but i want it to be interactable and when i do it, my health gets lowered and a text shows up.

2. I want an piano to play whenever i didn't look at it, and it suddenly stopped when i do, with a dust, as if someone was there.

3. In the original game, (in the Wine Cellar, to be exact.) a door was banging by it self and stops when you interact with it. How do i do this?

4. How do i roll the credits?

5. How do i destroy an object using an item?

More questions will come. But so far, those are the only problems.
