How can I make objects disappear when you walk on a specific area?

Somewhat new to Unreal 4 here. Simply put I want to make some objects in my scene disappear when you walk in a certain area. I’m assuming this has something to do with selecting an object or area to walk on and setting it so that when you walk on those it causes a different object to permanently disappear. Have no idea how to do this so I need some help!

You can use the DestroyActor node and the target would be a reference to that object you want to destroy. DestroyActor deletes that object from the game scene and from memory so it is gone forever.
