Why is instantiate and playerprefs not working when combined?

So I need to save a variable, called goodrandomvalue so that I can change the chance for spawn of the ball.

So this works:

    var goodball : GameObject;
    var badball : GameObject;
    var goldball : GameObject;
    var startaudio : GameObject;
    var camera1 :GameObject;
    var spawnwait = 2.5;
    var startingtext : GUIText;
    var goodrandomvalue = .6;
    InvokeRepeating("Spawn", 3, spawnwait);
    function Start () {
    yield WaitForSeconds (1);
    startingtext.text = "2";
    startaudio.audio.Play();
    yield WaitForSeconds (1);
    startingtext.text = "1";
        startaudio.audio.Play();
    yield WaitForSeconds (1);
    startingtext.text = "Begin!";
                Handheld.Vibrate ();
        startaudio.audio.Play();
    yield WaitForSeconds (.5);
   // Time.timeScale = 0.1;
    startingtext.text = "";
    }
    function Update () {
 //    spawnwait -= Time.deltaTime * .001;
    }
    
    function Spawn() {
           var goodclone : GameObject;
          var badclone : GameObject;
                    var goldclone : GameObject;
    Debug.Log("New Ball!");
           //Add Random Chance for spawn
                   if ( Random.value > goodrandomvalue) {
             goodclone = Instantiate(goodball, transform.position, transform.rotation);
             goodball.animation.Play("11");
             Destroy (goodclone, 8.5);
             }
             else if (Random.value < .55) {
             badclone = Instantiate(badball, transform.position, transform.rotation);
                        //  Destroy (badclone, 24.5);
                          badclone.name = "badclone";
badclone.transform.tag = "clone";
                          badball.animation.Play("1");  
           }
         
         else if (Random.value > .92) {
         goldclone = Instantiate(goldball, transform.position, transform.rotation);
                                   goldball.animation.Play(); 
                                   goldball.audio.Play();  
                                   camera1.animation.Play("launch");
         }
           
    }

but I need it to save goodrandomvalue, but when I do:

PlayerPrefs.SetInt("goodrandomvalue", .6);

and
if ( Random.value > PlayerPrefs.GetInt(“goodrandomvalue”)) {
Then the goodrandomvalue ball spawns every time. What am I doing wrong?
Sorry for the poor explanation, but thanks anyways.

You are passing a floating value to SetInt (which takes integer values), so it is getting truncated to ‘0’; Try:

PlayerPrefs.SetFloat("goodrandomvalue", .6);

Of course you’ll have to use GetFloat() to get the value;

You sir, are my new most favorite person in the world. Thank you for saving me hours of frustration, When I'm a gagilionare, I'll make sure to track you down a give you a million dollars. One more question though, would I have to put if (PlayerPrefs.GetFloat("goodrandomvalue") == 0){ PlayerPrefs.SetFloat("goodrandomvalue", .6); } so it only sets it one time, rather then every time I play the game? Thanks again,

If you only want to set it once, the use [PlayerPrefs.HasKey()][1]. So your code would look something like: if (!PlayerPrefs.HasKey("goodrandomvalue")){ PlayerPrefs.SetFloat("goodrandomvalue", .6); } Note the '!' symbol in the 'if' statement.

I could have never figured that out, I looked all over the docs too. There isn't much detail in the Playerprefs part of the docs. But would the way I said it work too? And what If I already made the key, but I wanted to change it one time? Thanks again, sorry for all the questions,

 –

Yes, your way would work. Looking at the script reference, if the key did not exist, it would return a default value of 0.0 (unless you define a different default value). As for "change it one time", you can add new keys, and either leave old one alone or delete them.

Thanks yet again,
