Save timer score between scenes? (C#)

Question

Hello my fellow Unities, I have a timer in my game that's counting upwards, the timer is also used for score so 30 seconds = 30 points. Now I'm trying to figure out how to save the timer score, when switching scenes. Say that you survive for 40 seconds, now I want to save that float number and load it into the other scene? Note that I change scene when an enemy collides with the player.

I have my timer code here:

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class TimerScript : MonoBehaviour 
 {
     //Create timer
     public float timer = 0f;
 
     //Create displayed timer
     Text text;
     
     void Awake()
     {
         //Load Text class
         text = GetComponent<Text> ();
 
         //Reset the timer
         timer = 0f;
 
     }
 
     void Update()
     {
         //Start the timer and keep it going
         timer += Time.deltaTime;
 
         //Write out the timer on the screen with one decimal
         text.text = "" + timer.ToString("F1");
     }
 }

And here's the change scene script when an enemy "kills" the player:

 public void OnCollisionEnter2D(Collision2D col)
     {
         if(col.gameObject.tag == "Player")
         {
             Application.LoadLevel(3);
         }
     }

Alright, so I kind of got it to work by using some good ol' IF statements, now the only problem is how do i stop the timer from counting when I'm in the next scene, and then reset it when going back again? (I have a reset button in the scene I'm loading in) If i write "Timer = 0" in the Awake fuction, it will be 0 in both scenes..

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class TimerScript : MonoBehaviour 
 {
     //Create timer
     public static float timer = 0f;
 
     //Bool
     bool stopTimer = false;
 
     //Create displayed timer
     Text text;
     
     void Awake()
     {
         //Load Text class
         text = GetComponent<Text> ();
         DontDestroyOnLoad (this.gameObject);
 
         //Reset the timer
         //timer = 0f;
 
     }
 
     void Update()
     {
         //Start the timer and keep it going
         timer += Time.deltaTime;
 
         //Write out the timer on the screen
         text.text = "" + timer.ToString("F1");
 
         if(Application.loadedLevelName == "Scene 2 Game over")
         {
             text.text = timer.ToString("F1") + " Points";
         }
 
         if(Application.loadedLevelName == "Scene 1 Main Game")
         {
             
         }
     }
 
 }

      if(Application.loadedLevelName == "Scene 1 Main Game")
      {
          timer += Time.deltaTime;
      }

There we go, thank you it works at last! :D I wrote what you said and then created a Start function and wrote:

 void Start()
     {
         if(Application.loadedLevelName == "Scene 1 Main Game")
         {
             timer = 0.0f;
         }
     }

Hello, @Internetman!

You can save the score value using the PlayerPrefs

  PlayerPrefs.SetFloat("Player Score", 10.0F);

And you can get the score in the other scene using

  float score = PlayerPrefs.GetFloat("Player Score");

If you save copy of timer as static variable, this should help

 static float timerCopy;
 function Start(){
 timer = timerCopy;
 }
 
 function Update(){
 timerCopy = timer
 }

add this code to the TimerScript & make the object that this script attached to a brefab after that drag the object into the next scene.

 void Awake()
 {
 DontDestroyOnLoad(this.gameObject);
 }
