How do I create and destroy an enemy made out of many sprite

Like in the title, i have 4 sprites:

• body
• head
• arm 1
• arm 2

Everything on creation is pinned to body.

There are some problems:

1. how do i make the body with parts to fade when not in line of sight

2. how do i destroy all the parts at once?

It's important to use less than 3 events. Please help.

When i put them in containter (body is container) the game won't start

Put them in a family instead?

Maybe post what you've got so far so someone can have a look.

I'm a free user, can't use families. Blackhornet, i can't give .capx :/, i'm working on this game pretty long

Screenshot your work and show us.

I can give the error when i do a container

okay. Now parts destroy 'if not pinned > destroy'. Still 1 thing left.
