What I can do for that the value of x,y of the same mouse position is the same in each game resolution in game view?

Questions & Answers
1

I have some validations with the position of the mouse, but in each resolution, the same position of the mouse is registered with different values.

try :

var positionNormalized_X : float = Input.mousePosition.x / Screen.width;
var positionNormalized_Y : float = Input.mousePosition.y / Screen.height;

this should always return a value between 0 and 1 for any screen resolution
