Question about one of the tutorials in youtube

Hi

In this video: Paper2D: Movement | 06 | v4.4 Tutorial Series | Unreal Engine - YouTube

He makes one of the inputs for “Touch 1” which is for the mobile devices. But in UE 4.9 there is not such an option. There is only “Stream touch” options. Which one should I use so I can have the same effect as the old “Touch 1” option?

Thanks.
