How to set and count Time and save record

I would like to set a timer when game level starts, when the player wins the game level, the timer stops.

The time period will be recorded and display everytime when game finishes.

So, the lowest time to complete a game level is the best result. Just like Pool Ninja.

How can I code it?

 

http://unity3d.com/support/documentation/ScriptReference/Time.html

Create a float variable that is going to keep track on time.

When the level/game starts, you set the variable to 0. In every Update your then just add the deltaTime.

Code (csharp):

1.  
2. var levelTimer : float;
3. var updateTimer : boolean;
4.  
5. function Start()
6. {
7.    levelTimer = 0.0f;
8. }
9.  
10. function Update()
11. {
12.    if (updateTimer)
13.       levelTimer += Time.deltaTime;
14. }
15.  
16. function LevelEnded()
17. {
18.    updateTimer = false;
19. }
20.  

Something along those lines.

 

may I ask?

1) The Time.deltaTime output 6 decimal places, how can I round it up to 2 decimal places?

2) How to store the levelTimer value in a local game?

 

If you want in second try this :

Code (csharp):

1. var timerInSecond = 0;
2. private var levelTimer = 0.0;
3. private var updateTimer = false;
4.  
5. function Start()
6. {
7.    updateTimer = true;
8.    levelTimer = 0.0;
9. }
10.  
11. function Update()
12. {
13.    if (updateTimer)  
14.       levelTimer += Time.deltaTime*1;
15.  
16.  
17.  /// float to int
18.  timerInSecond = Mathf.Round (levelTimer);
19. }
20.  
21. function LevelEnded()
22. {
23.    updateTimer = false;
24.  
25.    ///Save Time
26.    PlayerPrefs.SetInt("Time In Second", timerInSecond );
27. }
28.  

 

I just read http://unity3d.com/support/documentation/ScriptReference/Mathf.html

Seems it can only convert to int, but not able to have 2 decimal places, right?

 

Ok, I found an other way

Code (csharp):

1. var timerTex = ""; //Text for GUI
2. private var levelTimer = 0.0;
3. private var updateTimer = false;
4.  
5. function Start()
6. {
7.    updateTimer = true;
8.    levelTimer = 0.0;
9. }
10.  
11. function Update()
12. {
13.    if (updateTimer)
14.       levelTimer += Time.deltaTime*1;
15.       timerTex = levelTimer.ToString("f2"); //Time to texture with 2 decimal
16. }
17.  
18. function LevelEnded()
19. {
20.    updateTimer = false;
21.    PlayerPrefs.SetFloat("Time In Second", levelTimer ); //Keep Complete Time for compare and save
22. }

Enjoy !!

 

"var may only appear within a local variable declaration " how do i fix this?

Code (CSharp):

1. using System.Collections;
2. using UnityEngine.UI;
3. using System.Collections.Generic;
4. using UnityEngine;
5.  
6. public class PlayerController : MonoBehaviour {
7.  
8.     public float speed;
9.     public Text countText;
10.     public Text winText;
11.  
12.     private Rigidbody rb;
13.     private int count;
14.     private var levelTimer = 0.0;
15.     private var updateTimer = false;
16.  
17.     void Start ()
18.     {
19.         rb = GetComponent<Rigidbody> ();
20.         count = 0;
21.         SetCountText ();
22.         winText.text = "";
23.         var timerTex = "";
24.         updateTimer = true;
25.         levelTimer = 0.0;
26.    
27.     }
28.  
29.     void FixedUpdate ()
30.     {
31.         float moveHorizontal = Input.GetAxis ("Horizontal");
32.         float moveVertical = Input.GetAxis ("Vertical");
33.  
34.         Vector3 movement = new Vector3 (moveHorizontal * speed, 0.0f, moveVertical * speed);
35.  
36.         rb.AddForce (movement);
37.  
38.         if (updateTimer)
39.                 levelTimer += Time.deltaTime*1;
40.             timerTex = levelTimer.ToString("f2");
41.     }
42.  
43.     void OnTriggerEnter(Collider other)
44.     {
45.         if (other.gameObject.CompareTag ("Pick Up"))
46.         {
47.             other.gameObject.SetActive (false);
48.             count = count + 25;
49.             SetCountText ();
50.         }
51.     }
52.  
53.     void SetCountText ()
54.     {
55.         countText.text = "Count: " + count.ToString ();
56.         if (count >= 325) {
57.             winText.text = "You Win";
58.  
59.             updateTimer = false;
60.             PlayerPrefs.SetFloat("Time In Second", levelTimer );
61.    
62.         }
63.     }
64. }
65.  

 

try setting your variables to public instead of private.
