How can I make player not be able to shoot at certain a certain area

Hello,
So I have a game that I am currently making mobile, there is a mobile device joystick and a shoot function where you tap to shoot there. I have ran into a problem where when you do both at the same time the shooting doesn’t work at all. Is there any way to fix this so you can use both at once with no error?
Thanks!

Here is a photo for context:

I think the trick is you need to add a script called EventTrigger to your buttons to get MultiTouch.

At around the 9-minute mark this guy has it going:

I am not using buttons, I’m using a joystick pack (Fenerax studios) and touch to shoot, will this still work?

Sounds like a question Fenerax Studios could answer better than anyone else.
