I don’t want to be that guy but did anyone really watched what that guy is showing in that video 
?
Is because I don’t know how to create that at the moment, dealing with touches and what not.
what unreal starting module have touch input, with rotating camera that works on big screens and smalls phones, pinch and zoom, and the rest?
I can understand, you are watching the video thumbnail and you are thinking about joystick input.
is not mandatory but please watch the video from around minute 10 for five minutes to understand what I’m talking about.
