High-score Saving Issue

Questions & Answers
1

I want to implement a high score system in my dodge game, but I can’t seem to make it work. Currently, I have a score, which starts from 500,000 and gets down 150 points per seconds. This works, although when I die it still goes on, which I need to fix. I have a second kmHighscore Text, and I want it to show the highscore. Right now it shows the exact score on which I died(for example 450,875), but when I restart the game I can’t seem to make it be saved. I tried with PlayerPrefs, but I am not sure how to apply it in my code. I want it to represent the lowest, in this case as it starts from 500,000, score ever achieved. Just to note: Both kmScore and kmHighscore are just numbers, I don’t have text before the score or the highscore in the Unity window. Any help will be appreciated!

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.SceneManagement;

public class GameOver : MonoBehaviour {

    public GameObject gameOverScreen;
    public Text kmScore;
    public Text kmHighscore;
    float savedScore;
    bool gameOver;
    private float score = 500000;

    void Start () {
        FindObjectOfType<PlayerController>().OnPlayerDeath += OnGameOver;          
    }

    public void Update () {

        kmScore.text = GetScore().ToString("F0");

        if (gameOver)
        {
            if (Input.GetKeyDown (KeyCode.Space))
            {
                SceneManager.LoadScene(1);
            }
        }
    }


    float GetScore()
    {
        return score - (float)Time.timeSinceLevelLoad * 150;
    }


    void OnGameOver()
    {

        gameOverScreen.SetActive (true);
        kmHighscore.text = GetScore().ToString("F0");

    }
}

hi;
there are some things need to be done to fix this ;

first of all calculating the High Score should be only when its not game over so u should change this part in the update method :

then u need to save the score when u die and load it when the game starts again ;

to save the score u need to have another variable to store the last highscore cause u dont access that function when u die;

and at last u need to check if the current score is not more then your last saver high score ;

so it all changes like this

CurrentHighScore = 0; void Start() { FindObjectOfType().OnPlayerDeath += OnGameOver;

         if ( PlayerPrefs.HasKey("HighSScore"))
         {
            CurrentHighScore = PlayerPrefs.GetFloat("HighSScore");
            kmScore.text = CurrentHighScore.ToString("F0");
            
         }
     }
     float CurrentScore;
     public void Update()
     {
       
         if (gameOver)
         {
             if (Input.GetKeyDown(KeyCode.Space))
             {
                 if (CurrentScore > CurrentHighScore)
                 {
                     PlayerPrefs.SetFloat("HighSScore", HighestScore);
                 }
                 SceneManager.LoadScene(1);
             }
         }
         else
         {
             CurrentScore = GetScore();
             if ( CurrentScore > CurrentHighScore)
             { 
             kmScore.text = GetScore().ToString("F0");
             }
         }
     }
     float HighestScore;
     float GetScore()
     {
         HighestScore = score - (float)Time.timeSinceLevelLoad * 150;
         return HighestScore;
     }

i did this really quick so they mayebe some problem tell me about them if u see;

This is a good tutorial for easily implementing a save/load function with JSON.
if you want to use player prefs I’m pretty sure this tutorial covers saving/loading with that option.
