Detecting collision between two specific actors?

How would I detect the collision between two actors, being specific? I have a ball (projectile) and a box. I want to know how to detect when the ball hits the box so I can play a sound, and delete both the ball and box.

Nevermind, got it. I used tags.

Hey, Can you help me out. I cant figure out how to use tags to accomplish that.

In whatever actor blueprint you are checking collision for, in the details panel at the bottom there is a section called Tags, just add in a new tag and when you check for collision with Event Hit, use the Actor Has Tag node.
