Why isn't my score recording on the playerprefs is there GetFloat method? - unity3d

Question

Why isn't my score recording on the playerprefs ? is there GetFloat method? Can anyone help me to post the least score of my game it just like the most least seconds will get the best time record ever
var myTimer: float = 0;
var GUITimer: GUIText;
function Start() {
}
function Update() {
GUITimer.text = "Time: " + myTimer;
if (myTimer > -1) {
myTimer += Time.deltaTime;
}
}
function OnTriggerEnter(other: Collider) {
if (other.tag == "FinishLine") {
SaveTime();
}
}
function OnGUI() {
GUI.Label(Rect(10, 10, 500, 200), myTimer.ToString());
}
function SaveTime() {
if (myTimer < PlayerPrefs.GetInt("JeepneyScore3")) {
PlayerPrefs.SetInt("JeepneyScore3", myTimer);
}
Application.LoadLevel("Levels");
}

I see three problems:
First, you're tracking a float, but calling GetInt() and SetInt(). Keep your data types consistent. You should either round/floor/etc, or call GetFloat() and SetFloat().
Second, you're not calling Save(), which means your changes will never write to disk. You might consider something like this:
PlayerPrefs.SetFloat("JeepneyScore3", myTimer);
PlayerPrefs.Save();
Third, you're not handling the case where no data exists. You could check for existing data with HasKey(), but in this case it's simpler to rely on the second form of GetFloat(). The default form, which you're calling, returns zero if the requested key isn't set:
//returns value of "foo", or zero if no such value
var prevBest = PlayerPrefs.GetFloat("foo");
If you're looking for a time below the player's previous best, but the default "best" is already 0.0, you're going to have a hard time beating that time.
You can instead provide your own default value:
//returns value of "foo", or ten thousand if no such value
var prevBest = PlayerPrefs.GetFloat("foo", 10000.0);
Finally, you should make sure that SaveTime() is actually being called at the appropriate time. You could add a simple debug line, like this:
Debug.Log("SaveTime was called");
And then make sure that's showing up. If not, you need to fix your collision check.
