Melee weapon

Hello, I want to create a melee weapon wich, when overlapping an object, it gets destroyed. I already created an AI (wich will be the enemy) and I imported a hammer from the community content, but I don't know how to make it so when a player attacks that enemy, it dies (get destroyed or something).
Could you please help me?

How are your AI enemies built? Are you using the NPC Kit, or Damegable Objects?
