Question of Animation and Component

I’m trying to make melee attack.

I try two ways, and all fail.

Now I want to check that my code work.

Question is,

  1. I want to see the area of component. Is there any way to add color on component?
  2. When character make collision with other character’s hitbox, Is there any way to check some parts of character is overlapped? For example, I want to add reaction when just hands is overlapped.
  3. If I make socket under the any parts of skeletal and when animation played, Does Component which is attached to socket move with socket?

I need to know that because I need them to check my code work.
