Rotate Floor with Leap Motion Controller

Hi, I hope somebody can help me. I have a Problem with the Leap Motion Controller in Unreal Engine 4.9. I use the official Plugin, that is in Plugin Browser of Unreal. But I am new at Unreal Engine and I want to rotate the Floor of my game. If nobody can help, it would help to see a Blueprint that rotate an other object. Thank you very much in advance for your answer.
