Mobile support for GetMouse

So I never script on making support to any mobile devices but I have a weapon system that only triggers to shoot on mouse but not on for mobiles. How should I change this script function to make this possible for mobiles to shoot?

I’m pretty sure :GetMouse works on mobile too. It’ll get he position that the user taps on the screen.

UserInputService.TouchTap as you can see here it has touchpositions argument

Strange… For some reason it dose not work for the mobile users.
