How do I change the camera view to look around?

I have 2 unrealted questions :

1. I am following my main player on the level using scroll-to behavior. How to temporarily pause that and look around the level and then go back to the player once the look around is done?

2. if I make copies of an object, how do I destroy these 2 objects on Collision with either one (collision with a 3rd object). The copy is done by copy/paste?

another question:

3. Is there to check for object A collision with "any" object, then play the same sound. I dont want to check for collision with each specific object and play the same sound

For camera management I usually prefer to use a separated camera object that follows the player, it's easier to then do stuff like moving the camera away from the player or even add some offset, so the player is not centered in specific situations.
