Moving Click Ingame Button

Hello Guys,
I’m really new to this software.
Although I’ve read through loads of Forums I still haven’t found a solution for my problem:
So, how is it possible to create an 3dimensional, in-game Button, which moves down and up when I trigger it with mouse input?
Should I use a Level Sequence for that or something else? I hope some of you is able to tell me a bit of instructions for using this powerful, but complex Engine.
Thanks in advance and sorry for my bad English

Let’s try this on two steps:

1 - Covert your button to an actor, and create a function on it to be called when the click happens.

2 - Use the ConvertMouseLocationToWorldSpace to make a Line Trace, if the collided object is your button, then call the click function.
