How to make an object undestructible?

Hey Guys,

Thank you for the answer. Really appreciate it.
I tried everything you guys said but the problem I faced is that I have a lot of objects in
my scene that do different things therefore they are added as different blueprints.
Could I somehow create a Clickable blueprint and make the other blueprints its children?
Or could I just make a blueprint of the few objects I want to make undestructible so when I run a
branch it just identifies what can not be destroyed?
