My problem is i dont know how to save a highscore i have looked at tutorials but none of them work and i cant figure it out so if one of you could help it would much be appreciated here is my script

using UnityEngine;

public class Generate : MonoBehaviour
{
public GameObject rings;
int score = 0;

// Use this for initialization
void Start()
{
	InvokeRepeating("CreateObstacle", 1f, 1.5f);
}

// Update is called once per frame
void OnGUI () 
{
	GUI.color = Color.red;
	GUILayout.Label(" Score: " + score.ToString());
}

void CreateObstacle()
{
	Instantiate(rings);
	score++;
}

}

You might want to look into PlayerPrefs

Here is an example,

int Highscore = 0;
 void Start()
 {
      //loading highscore 
     Highscore = PlayerPrefs.GetInt("MyHighscore");
    
     InvokeRepeating("CreateObstacle", 1f, 1.5f);
 }

void CreateObstacle()
 {
     Instantiate(rings);
     score++;

     //saving highscore 
     Highscore = PlayerPrefs.SetInt("MyHighscore",score);

 }

PlayerPrefs.SetInt may have a slight performance issue if called every frame ( especially on mobiles). So try to save at the end of the scene, on exit or at some checkpoint.

You can do the following as soon as your game/level/round is finished. It’ll save the highscore to the PlayerPrefs:

// loads the value for "highscore", returns the default 0 if it doesn't exist
int highscore = PlayerPrefs.GetInt("highscore", 0);
if(highscore < score)
{
    // saves the value of "score" into the highscore field
    PlayerPrefs.SetInt("highscore", score);
}
