How to save the resolution of screen between scenes

Questions & Answers

Hi, i’m doing the options menu for the game (the resolutions) and i now have all the code that i need but i don’t know how to save it with the player prefs, basically I would like to save the resolution of the dropdown and the state of fullscreen between scenes. As now the code starts with a resolution but it doesn’t save the selected resolution (the text of the dropdown options, the resolutions itself remains between scenes) or the state toggle of the fullscreen when I change from the main menu to the game scene.

using UnityEngine;
using UnityEngine.UI;

public class setting_menu : MonoBehaviour

{
List widths = new List () {3840, 2560, 1920};
List heights = new List () {2160, 1440, 1080};

 void Awake()
 {
    SetResolution(1);
 }

 public void SetFullscreen(bool isFullscreen)
 {
     Screen.fullScreen = isFullscreen;
 }

 public void SetResolution(int resolutionIndex)
 {
    bool fullScreen = Screen.fullScreen;
    int width = widths[resolutionIndex];
    int height = heights[resolutionIndex];
    Screen.SetResolution(width, height, fullScreen);
 }

}

I did this following a tutorial on Youtube
Thanks for the help!

public static List widths = new List () {3840, 2560, 1920};
public static List heights = new List () {2160, 1440, 1080};

with static you will be able to keep the value when changing scene

saving it with player prefs is not any different than saving other values , you simply define one key for width and one for height and save the values there ,
better than using static values since they only remain in current game session
so it will something like this :

  private const string SCREEN_WIDTH = "sc_width";
  private const string SCREEN_HEIGHT = "sc_height";

   PlayerPrefs.SetInt(SCREEN_WIDTH , 3840);

   PlayerPrefs.SetInt(SCREEN_HEIGHT, 2160);
