Server based highscores:

http://www.unifycommunity.com/wiki/index.php?title=Server_Side_Highscores

Pretty straightforward.

@MikezNesh

For a local highscore save data on PlayerPrefs (if it's not full) Do this:

function AddScore(name : String, score : int){
   var newScore : int;
   var newName : String;
   var oldScore : int;
   var oldName : String;
   newScore = score;
   newName = name;
   for(i=0;i<10;i++){
      if(PlayerPrefs.HasKey(i+"HScore")){
         if(PlayerPrefs.GetInt(i+"HScore")<newScore){ 
            // new score is higher than the stored score
            oldScore = PlayerPrefs.GetInt(i+"HScore");
            oldName = PlayerPrefs.GetString(i+"HScoreName");
            PlayerPrefs.SetInt(i+"HScore",newScore);
            PlayerPrefs.SetString(i+"HScoreName",newName);
            newScore = oldScore;
            newName = oldName;
         }
      }else{
         PlayerPrefs.SetInt(i+"HScore",newScore);
         PlayerPrefs.SetString(i+"HScoreName",newName);
         newScore = 0;
         newName = "";
      }
   }
}

To display the high score set up a GUI to display the text and int in a table and store the information from player prefs in variables. Initialise the high score table by calling AddScore at the start of your game.

var 1stScore : int; var 1stName : String; var 2ndScore : int; var 2ndName : String; etc...

function UpdateHScore(){
   1stScore = PlayerPrefs.GetInt(0HScore);
   1stName = PlayerPrefs.GetString(0HScoreName);
   etc....
}

Alternatively use PlayerPrefsX from the wiki:

One trick I use for storing a bunch of stuff like that in playerprefs is just to use JSON. That way I can just serialize a hash table to a string and store it that way.

So in using this on an android game, it'll store the players name just fine, but it won't store the score - it simply puts a 0 in there :(

Hi this is a very simple high score system for saving a int score and a name. Hope the code is clear

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 
 
 /// <summary>
 /// High score manager.
 /// Local highScore manager for LeaderboardLength number of entries
 /// 
 /// this is a singleton class.  to access these functions, use HighScoreManager._instance object.
 /// eg: HighScoreManager._instance.SaveHighScore("meh",1232);
 /// No need to attach this to any game object, thought it would create errors attaching.
 /// </summary>
 
 public class HighScoreManager : MonoBehaviour
 {
     
     private static HighScoreManager m_instance;
     private const int LeaderboardLength = 10;
     
     public static HighScoreManager _instance {
         get {
             if (m_instance == null) {
                 m_instance = new GameObject ("HighScoreManager").AddComponent<HighScoreManager> ();                
             }
             return m_instance;
         }
     }
     
     void Awake ()
     {
         if (m_instance == null) {
             m_instance = this;            
         } else if (m_instance != this)        
             Destroy (gameObject);    
         
         DontDestroyOnLoad (gameObject);
     }
     
     public void SaveHighScore (string name, int score)
     {
         List<Scores> HighScores = new List<Scores> ();
 
         int i = 1;
         while (i<=LeaderboardLength && PlayerPrefs.HasKey("HighScore"+i+"score")) {
             Scores temp = new Scores ();
             temp.score = PlayerPrefs.GetInt ("HighScore" + i + "score");
             temp.name = PlayerPrefs.GetString ("HighScore" + i + "name");
             HighScores.Add (temp);
             i++;
         }
         if (HighScores.Count == 0) {            
             Scores _temp = new Scores ();
             _temp.name = name;
             _temp.score = score;
             HighScores.Add (_temp);
         } else {
             for (i=1; i<=HighScores.Count && i<=LeaderboardLength; i++) {
                 if (score > HighScores [i - 1].score) {
                     Scores _temp = new Scores ();
                     _temp.name = name;
                     _temp.score = score;
                     HighScores.Insert (i - 1, _temp);
                     break;
                 }            
                 if (i == HighScores.Count && i < LeaderboardLength) {
                     Scores _temp = new Scores ();
                     _temp.name = name;
                     _temp.score = score;
                     HighScores.Add (_temp);
                     break;
                 }
             }
         }
         
         i = 1;
         while (i<=LeaderboardLength && i<=HighScores.Count) {
             PlayerPrefs.SetString ("HighScore" + i + "name", HighScores [i - 1].name);
             PlayerPrefs.SetInt ("HighScore" + i + "score", HighScores [i - 1].score);
             i++;
         }
         
     }
 
     public List<Scores>  GetHighScore ()
     {
         List<Scores> HighScores = new List<Scores> ();
 
         int i = 1;
         while (i<=LeaderboardLength && PlayerPrefs.HasKey("HighScore"+i+"score")) {
             Scores temp = new Scores ();
             temp.score = PlayerPrefs.GetInt ("HighScore" + i + "score");
             temp.name = PlayerPrefs.GetString ("HighScore" + i + "name");
             HighScores.Add (temp);
             i++;
         }
 
         return HighScores;
     }
     
     public void ClearLeaderBoard ()
     {
         //for(int i=0;i<HighScores.
         List<Scores> HighScores = GetHighScore();
         
         for(int i=1;i<=HighScores.Count;i++)
         {
             PlayerPrefs.DeleteKey("HighScore" + i + "name");
             PlayerPrefs.DeleteKey("HighScore" + i + "score");
         }
     }
     
     void OnApplicationQuit()
     {
         PlayerPrefs.Save();
     }
 }
 
 public class Scores
 {
     public int score;

     public string name;
 
 }

to check if this work check the following script, just add this to a game object and you will be able to check its functionality

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 
 public class MenuController : MonoBehaviour {
 
     string name="";
     string score="";
     List<Scores> highscore;
     
     // Use this for initialization
     void Start () {
         EventManager._instance._buttonClick += ButtonClicked;
         
         highscore = new List<Scores>();
         
     }
     
     
     void ButtonClicked(GameObject _obj)
     {
         print("Clicked button:"+_obj.name);
     }
     
     // Update is called once per frame
     void Update () {
         
     }
     
     void OnGUI()
     {
         GUILayout.BeginHorizontal();
         GUILayout.Label("Name :");
         name =  GUILayout.TextField(name);
         GUILayout.EndHorizontal();
         
         GUILayout.BeginHorizontal();
         GUILayout.Label("Score :");
         score =  GUILayout.TextField(score);
         GUILayout.EndHorizontal();
         
         if(GUILayout.Button("Add Score"))
         {
             HighScoreManager._instance.SaveHighScore(name,System.Int32.Parse(score));
             highscore = HighScoreManager._instance.GetHighScore();    
         }
         
         if(GUILayout.Button("Get LeaderBoard"))
         {
             highscore = HighScoreManager._instance.GetHighScore();            
         }
         
         if(GUILayout.Button("Clear Leaderboard"))
         {
             HighScoreManager._instance.ClearLeaderBoard();            
         }
         
         GUILayout.Space(60);
         
         GUILayout.BeginHorizontal();
         GUILayout.Label("Name",GUILayout.Width(Screen.width/2));
         GUILayout.Label("Scores",GUILayout.Width(Screen.width/2));
         GUILayout.EndHorizontal();
         
         GUILayout.Space(25);
         
         foreach(Scores _score in highscore)
         {
             GUILayout.BeginHorizontal();
             GUILayout.Label(_score.name,GUILayout.Width(Screen.width/2));
             GUILayout.Label(""+_score.score,GUILayout.Width(Screen.width/2));
             GUILayout.EndHorizontal();
         }
     }
 }

Answer by Danboe2009 · Aug 01, 2012 at 12:32 AM

I used the code above and I feel like it goes in to a loop uncontrolled. Here is an example of what happens. If the player gets a new score that is higher then the highest score then it wipes out the old score and replaces it with the highest.

So: Dan : 75 Dan : 50 Dan : 25 Dan : 25 Dan : 25

Becomes: Dan : 100 Dan : 100 Dan : 100 Dan : 100 Dan : 100

are you sure you haven't forgotten the newscore = oldscore; part in the loop? it makes sure the next time the loop is called it will be using the score that got overthrown by the new highscore, by putting it in the newscore variable
