2D Android - Attack where the player is looking - HELP

Hi there, i’m making a 2d roguelike (Z and X axis) for android and i cant figure out how to attack where the player is looking. I know how to do this with a Action Key or with the same movement direccion, but i can’t make it with a button widget.
This is my movement blueprint

The problem,

With this i can solve it, but is key pressing.

I tried to make function with ( move foward, move right and make vector) but didn’t work.
