help with an aspect ratio screen

My doubt is the following, I want to put a guitexture on the screen but do not know how to do it does not change position when changing screen resolution as I could do?

Set all of the Pixel Inset values (x,y, width, height) to 0.

Now the “scale” and “position” are both normalized from 0-1, where:

  • For scale: 1 = 100% of the screen
    (covers its entirely) and 0 = does
    not cover it at all
  • For Position: x = 0 = left most and 1= right most corner.
  • For Position: y = 0 = bottom, and y = 1 = top
