DontDestroyOnLoad reset the gameobject
Hi,
I'm having a flappy bird kind of game. I would like to have previous score shown on the screen when I die and start it all over. Somehow I don't manage to do so. However the best scores shows at it should (and all the other text element).
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class GameControlScript : MonoBehaviour
{
public Text scoreText;
public GameObject gameOvertext;
public Text lastScoreText;
public Text bestScoreText;
int bestScore = 0;
int score = 0;
bool isGameOver = false;
void Awake()
{
bestScore = PlayerPrefs.GetInt ("best", 0);
}
void Update()
{
//if the game is over and the player has pressed some input...
if (isGameOver && Input.anyKey)
{
//...start a new game.
Application.LoadLevel(Application.loadedLevel);
}
bestScoreText.text = "Best: " + bestScore;
}
public void Scored()
{
score++;
scoreText.text = "Score: " + score;
}
public Died()
{
gameOvertext.SetActive (true);
isGameOver = true;
lastScoreText.text = "LAST: " + score;
//check if high scored
if (score >= bestScore)
{
PlayerPrefs.SetInt("best", score);
PlayerPrefs.Save();
}
}
}
Then again I have an extra script for lastScoreText only which is named NoDestroy:
using UnityEngine;
using System.Collections;
public class NoDestroy : MonoBehaviour {
void Awake (){
DontDestroyOnLoad (this.gameObject);
}
}
but it still reset my "last score" when I restart the level. I don't know why, but appreciate if someone could help me. I have also tried to put empty gameobject and place lastScoreText there, but the results are same. So the question is: How I can modify the code so it won't reset my lastScoreText when restarting the level?
Well your best score is using player prefs to save the score to the registry. So do the same with your last score?
public class GameControlScript : MonoBehaviour
{
int lastScore = 0;
}
void Awake()
{
lastScore = PlayerPrefs.GetInt ("last", 0);
}
public Died()
{
gameOvertext.SetActive (true);
isGameOver = true;
lastScoreText.text = "LAST: " + lastScore;
PlayerPrefs.SetInt("last", score);
//check if high scored
if (score >= bestScore)
PlayerPrefs.SetInt("best", score);
PlayerPrefs.Save();
}
Thanks for the reply.
Yes, that's a one option, but I thought it might be easier use just DontDestroyOnLoad.
Should I also save it (PlayerPrefs.Save) after setting the last score? Does that disturb also the best score field? Or would it replace only the changed field?
Is there a difference with the performance using PlayerPrefs or DontDestroyOnLoad?
Thanks again.
Yes if your using DontDestroyOnLoad you dont really need playerprefs. But since you started with playerprefs i thought you wanted to use it. PlayerPrefs.Save() will save all the values you have set, so you only need to call it once. I would use playerprefs only if you need to save the score across diffrent ga$$anonymous$$g sessions. And use the DontDestroyOnLoad method if you dident need to see the "last score" next time you start the game. About the performance im not sure.
