How to recalculate x,y coordinates based on screensize

Have you tried this mathematical formula to change the range of a number?

And also instead of storing this:

x,   y,   width, height
433, 343, 1257,  959
331, 823, 1257,  959

You could store it normalized between 0 and 1 so it works for any width/height (calculated by dividing each x by its width and each y by its height):

x,     y
0.344, 0.357
0.263, 0.858

Then you don’t need to know the width/height you used when you stored them, and when you want to translate them to the size of the current screen you just multiply each one by the current width/height
