Script Reference Through Scenes?

Unity Engine
,
1

I’m making a high score on my game (Brackeys How To Make A Video Game), and have added random gen infinite levels, and to get into one of the infinite modes you go through a menu that has a button for easy, medium, and hard. Here I want it to show your high score. The score is how far you have went (amount of blocks) in the infinite mode, but I have to reference the score in the infinite mode to the menu for the high score.
I have looked at other posts that tell you to link the data to a GameObject, but it is a separate scene, so I would have to put a score text GameObject in, but would have no reference to the rb.position.z (players y coordinate)
I hope I explained this well

Thanks

What you’re looking for is basically called a GameManager.

ULTRA-simple static solution to a GameManager:

OR for a more-complex “lives as a MonoBehaviour” solution…

Simple Singleton (UnitySingleton):

Some super-simple Singleton examples to take and modify:

Simple Unity3D Singleton (no predefined data):

Unity3D Singleton with a Prefab (or a ScriptableObject) used for predefined data:

These are pure-code solutions, do not put anything into any scene, just access it via .Instance!

If it is a GameManager, when the game is over, make a function in that singleton that Destroys itself so the next time you access it you get a fresh one, something like:

public void DestroyThyself()
{
   Destroy(gameObject);
   Instance = null;    // because destroy doesn't happen until end of frame
}

sorry I meant players z coordinate

Thanks, I should have thought of this, I kind of regret asking this, I already had a game manager

using UnityEngine;
using UnityEngine.SceneManagement;
using UnityEngine.UI;

public class GameManager : MonoBehaviour {
  bool gameHasEnded = false;
  public float restartDelay = 1f;

  public GameObject CompleteLevelUI;
  public Text TextUI;
  public Text highScore;



  public void SetHighScore() {
    highScore.text = PlayerPrefs.GetInt("highScore", TextUI).ToString();

  }


  public void CompleteLevel ()
  {
    CompleteLevelUI.SetActive(true);
  }
  public void EndGame ()
  {
    if (gameHasEnded == false)
    {
      PlayerPrefs.SetInt("highScore", TextUI);
      gameHasEnded = true;
      Debug.Log("GAME OVER");
      Invoke("Restart", restartDelay);
    }

  }

  void Restart ()
  {

    SceneManager.LoadScene(SceneManager.GetActiveScene().name);
  }

}

Hey, its giving me this error when I use this
Assets/scripts/GameManager.cs(29,39): error CS1503: Argument 2: cannot convert from ‘UnityEngine.GameObject’ to ‘int’
and when I define it as a int it can’t have the “TextUI” value

Some help to fix “Cannot implicitly convert type ‘Xxxxx’ into ‘Yyyy’:”

Specifically if you want to take the integer out of Playerprefs and manipulate it, it has to stay an integer, not get turned into a string. You are also trying to pass the UIText Object. That’s not a string or an integer.

If all you need is high score storage, here’s something much simpler:

Tracking simple high score / low time single-entry leaderboard:

For the highest score: Unity High score tracking - Pastebin.com

Usage:

TheBest.RecordScoreIfHigher( lastGamePlayScore);

For the lowest time: Unity best time tracking - Pastebin.com

Usage:

TheBest.RecordTimeIfLower( lastGamePlayTime);

To retrieve the best score or time, use one of these:

int bestScore = TheBest.BestScore;

float bestTime = TheBest.BestTime;

Full usage example:

so for the first one I remove .ToString?

Check out some basic C# tutorials on data types so you can understand the difference between a number 123 and the string “123” so you can reason about the issue at hand.

// these are NOT the same thing

int number1 = 123;

string number2 = "123";

Both perfectly legal, both has a place and a purpose. Go learn why.
