How make Hint when im look at interact object?

Hello. I have some interactive object (like in this lesson - YouTube) in my level. Me need make appearing Hint in myHUD when im looking on object, and hide hint when dont look at the definite distantion, example 150 or 200. This is FPS project. Hint text must get from Interact object. Can you make tutorial?
P.S.
Sorry my bad english

I have a working solution to your problem.You need to create a blueprint interface. Name it “Interaction Interface”. Add this to your character, HUD and object blueprints so they can communicate with each other. The process works like this:

  1. You’ll trace a line from the point of the camera for a certain distance (for visibility channel).
  2. When the line collides with an inventory object, your character will send a blueprint interface message to that object and ask its name. This ensures that no message will be displayed if the object you’re looking at is not an interaction object.
  3. The object will send a blueprint interface message and tell its name to the character.
  4. The character will tell the HUD the name.
  5. The HUD will draw the name under the crosshair.

Would this be enough for you to figure it out on your own, or would you need some screenshots?

Thx. But im solved this question time ago. And now making video tutorial.
