PlayerPrefs saving bools to unlock a level

Question

Hi all..... i dont want to bother you with this frequently asked question about playePref.... but i cant understand whatever i am trying...... I have a trigger and when the trigger is entered my bool goes true...... but when i quit the application it restarts and the bool is false once again......

using UnityEngine; using System.Collections;

 public class trigger : MonoBehaviour {
     
     void OnTriggerEnter(Collider other){
         if(other.gameObject.tag == "cube"){
             
              
             Application.LoadLevel(0);
             levelhi.locklvl = true;
      }
 }
 
 
 }
 //

and this is the menu level managers...

 using UnityEngine;
     using System.Collections;
 
     public class levelhi : MonoBehaviour {
                 
                 public static bool locklvl = false;
                 
     public void OnClick() {
             if(locklvl==true)
             Application.LoadLevel (2);
     }
         // Use this for initialization
         void Start () {
             if(locklvl==false){
                              Destroy(gameObject);
                         
             }
         
         
         }
             
     }

You aren't properly saving the PlayerPrefs. PlayerPrefs are tricky to learn, but once you get the hang of them they are SUPER EASY. Watch this tutorial, this is how I learned: https://www.youtube.com/watch?v=AzypHv5nBEc

And read the docs: http://docs.unity3d.com/ScriptReference/PlayerPrefs.html

PlayerPrefs are pretty much the same in C# as in JS.

Also, if you're having issues with bool, try using Int. While it isn't "correct", for many purposes an Int value will work just as well as a bool. For example whenever I need to make a switch, the "correct way" is to use Bool True/False, but I use Int = 1 for True and Int = 0 as false. Easier for me :)

Don't forget to accept the best answer :)
