Save and Retrieve Score not working!
Dear all, I have been encountering a very irritating problem when creating my first app. I am trying to use the playerpref to save my score, but when it restarts, the highscore is reset to 0. I am an absolute beginner, so please treat me like a dunce. Ill paste the 2 scripts I have for scoring a point on trigger, and the other is the general score system. I have tried this on my phone, and whenever I score a point and update the score, the highscore is 0. Many thanks for the help :) from fatmanspineapple For the score point using UnityEngine; using System.Collections;
public class ScorePoint : MonoBehaviour {
void OnTriggerEnter2D(Collider2D collider){
if(collider.tag == "Player"){
ScoreSystem.AddPoint();
gameObject.SetActive(false);
}
}
}
For the score system
using UnityEngine;
using System.Collections;
public class ScoreSystem : MonoBehaviour {
static int score = 0;
static int highScore = 0;
static ScoreSystem instance;
static public void AddPoint(){
score++;
if (score > highScore) {
highScore = score;
}
}
void Start() {
PlayerPrefs.GetInt("highScore", 0);
}
void OnDestroy(){
PlayerPrefs.SetInt ("highScore", highScore);
score = 0;
}
void Update () {
guiText.text = "S:" + score + "\nHS:" + highScore;
}
}
You need to save your PlayerPrefs in order for the changes to be made to the disc. Use PlayerPrefs.Save();
void OnDestroy(){
PlayerPrefs.SetInt ("highScore", highScore);
// This line is important
PlayerPrefs.Save();
score = 0;
}
I was also wondering whether there was a code I could use to display this highscore on a different screen? After the game object collides with a killing game object, a screen is loaded and this highscore is displayed.
Dear Harshad, I tried this on my phone. The highscore saves but when I close the app and then reopen it, the high score resets to 0 again. i have tried everything and Im not sure what to do now

you never initialize highScore from player prefs - line 20:
PlayerPrefs.GetInt("highScore", 0);
should be
highScore = PlayerPrefs.GetInt("highScore", 0);
