Need help with PlayerPrefs!

Unity Engine

Here’s the code:

using UnityEngine;
using System.Collections;
using System;

public class Finish : MonoBehaviour {

	private Player bike;
	private CountDownTimer countDownTimer;
	public bool finished = false;
	private int episode;
	private int currentLevel;
	public int stars;
	private int getUnlock;
	public int starsLevel;

	private LevelButtons level;

	void Awake() {

		stars = 0;

		starsLevel = PlayerPrefs.GetInt("Episode:" +episode +"Level:"+currentLevel +"Stars:");

		print("STARS COLLECTED ALREADY: " + starsLevel);

		bike = GameObject.Find("PlayerBike").GetComponent<Player>();
		countDownTimer = GameObject.Find("GameScripts").GetComponent<CountDownTimer>();

		if (GameControl.control.episode1 == true)
		{
			episode = 1;
		}

		currentLevel = LevelButtons.levelControl.highestLevel + 1;

		// Check if level was finished before, and don't unlock new level if it was.
		getUnlock = PlayerPrefs.GetInt("Episode:" +episode +"Level:"+currentLevel +"Finished:");
		print(getUnlock);
	}
	

 	IEnumerator OnTriggerExit2D(Collider2D finish) {
		if (finish.gameObject.tag == "Player"  finished == false)
		{
			finished = true;
			if (finished == true){
				countDownTimer.StartTheTimer = false;
				bike.playerDisable = true;

				if (stars > starsLevel){
					PlayerPrefs.SetInt("Episode:" +episode +"Level:"+currentLevel +"Stars:",stars);
					print("STARS COLLECTED: " + stars);
				}

				// Unlock new level if the level is finished for the first time.
				if (bike.StarsCollected > 0  getUnlock == 0){
					// Unlock en ny level.
					//PlayerPrefs.SetInt("Episode:" +episode +"Level:"+currentLevel,1);
					// Legg antall stjerner i en PlayerPref.
					PlayerPrefs.SetInt("Episode:" +episode +"Level:"+currentLevel +"Stars:",stars);
					
					PlayerPrefs.SetInt("Episode:" +episode +"Level:"+currentLevel +"Finished:",1);
					
					print("LEVEL UNLOCKED!!");
				}

				yield return new WaitForSeconds(1);

				Application.LoadLevel("epLevels1");

			}
		}

	}

	void Update () {
		stars = bike.StarsCollected;
	}

My problem is this:

PlayerPrefs.SetInt("Episode:" +episode +"Level:"+currentLevel +"Stars:",stars); won’t save!

So everytime I read the starsLevel = PlayerPrefs.GetInt("Episode:" +episode +"Level:"+currentLevel +"Stars:");
it is always equal to 0.

why?

try PlayerPrefs.Save(); after you set the value.

For some reason it doesn’t work :S
If I set the PlayerPref.SetInt in the Awake function it works, but I need it to happen when the collision event occurs

4

Out of curiosity why do you have the IEnumerator on the line

IEnumerator OnTriggerExit2D(Collider2D finish)

shouldn’t it be
void OnTriggerExit2D(Collider2D other)
and using Trigger collision in the level?

I take it the print statements in this trigger method are telling you stars != 0?

Maybe try saving as Munchy said but on finishing the level at a single point, on this object disabling

No, since coroutines must return IEnumerator.

But why are you using it as a coroutine when it is a MonoBehaviour message?

https://docs.unity3d.com/Documentation/ScriptReference/MonoBehaviour.OnTriggerExit2D.html

Why wouldn’t you use it as a coroutine? It’s perfectly reasonable. The docs specifically mention it (at least the docs for OnTriggerExit, but the same applies to OnTriggerExit2D).

So they do must have missed that … glad I asked always good to find another way of doing something

Did you solve your original problem?

No I did not solve the problem.
Everything works just fine until I do this

PlayerPrefs.SetInt("Episode:" +episode +"Level:"+currentLevel,1);

Then all the info just disappears… I will try to do something other than PlayerPrefs, since they’re also unsafe
