I was trying to make it do you could only shoot when touching the left side of the screen. I figure I would just add another if parameter, but I don't really know how to add it. (Mobile game)

T$$anonymous$$s was the error that showed up:

Error CS1061 'bool' does not contain a definition for 'position' and no accessible extension method 'position' accepting a first argument of type 'bool' could be found (are you missing a using directive or an assembly reference?)
