C# Random Timer on screen display using GUItext

Hi all,

Super beginner Unity C# programmer here looking for some help.

My overall goal is to have random text with a random timer display to the Gui.

What I have so far;

using UnityEngine;
using System.Collections;

public class Countdown : MonoBehaviour
{
public float timer;
public float timerLimit = 30.0f;
public GUIText timerText;

// Use this for initialization
void Start ()
{
timer = timerLimit;
SetTimerText ();
}

// Update is called once per frame
void Update ()
{
timer -= Time.deltaTime;
SetTimerText ();
if (timer <= 0.0f)
{
print ("GAME OVER!");
timer = timerLimit;
}

}
public void SetTimerText()
{
timerText.text = "Checkpoint Alarm : " + timer.ToString ("f0");
}
}


This works fine to display "SPECIFIC" text and time,


What I am playing with (using a List);

objectTimers = new List<ObjectTimer>();

objectTimers.Add(new ObjectTimer("Kitchen Alarm: ", Random.Range (20, 120));
objectTimers.Add(new ObjectTimer("Storage Alarm: ", Random.Range (20, 120));
objectTimers.Add(new ObjectTimer("Game Room Alarm: ", Random.Range (20, 120));
objectTimers.Add(new ObjectTimer("Private Party Room Alarm: ", Random.Range (20, 120));
objectTimers.Add(new ObjectTimer("Shop Alarm: ", Random.Range (20, 120));
objectTimers.Add(new ObjectTimer("Office Alarm: ", Random.Range (20, 120));
objectTimers.Add(new ObjectTimer("Resturaunt Alarm: ", Random.Range (20, 120));


But I can't figure out how to get that randomness to take the place of my Specific from above.

Any help would be really appreciated.

Thank you!

Tom

 

Please use code tags to help us read your code.

 

Sorry! Not sure what a code tag is. Looking it up.

 

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Countdown : MonoBehaviour
5. {
6. public float timer;
7. public float timerLimit = 30.0f;
8. public GUIText timerText;
9.  
10. // Use this for initialization
11. void Start ()
12. {
13. timer = timerLimit;
14. SetTimerText ();
15. }
16.  
17. // Update is called once per frame
18. void Update ()
19. {
20. timer -= Time.deltaTime;
21. SetTimerText ();
22. if (timer <= 0.0f)
23. {
24. print ("GAME OVER!");
25. timer = timerLimit;
26. }
27.  
28. }
29. public void SetTimerText()
30. {
31. timerText.text = "Checkpoint Alarm : " + timer.ToString ("f0");
32. }
33. }

 

Code (CSharp):

1. objectTimers = new List<ObjectTimer>();
2.  
3. objectTimers.Add(new ObjectTimer("Kitchen Alarm: ", Random.Range (20, 120));
4. objectTimers.Add(new ObjectTimer("Storage Alarm: ", Random.Range (20, 120));
5. objectTimers.Add(new ObjectTimer("Game Room Alarm: ", Random.Range (20, 120));
6. objectTimers.Add(new ObjectTimer("Private Party Room Alarm: ", Random.Range (20, 120));
7. objectTimers.Add(new ObjectTimer("Shop Alarm: ", Random.Range (20, 120));
8. objectTimers.Add(new ObjectTimer("Office Alarm: ", Random.Range (20, 120));
9. objectTimers.Add(new ObjectTimer("Resturaunt Alarm: ", Random.Range (20, 120));

 

OK! found it, sorry about that.

Where is this code located? I can't see what you're doing with the objectTimers list. I'm also not sure what ObjectTimer does, since I can only see the CountDown class.

SetTimerText() sets a very specifc string to your GUI text. You should probably create a clock name member and use that instead of the explicit string you're using now.

Code (CSharp):

1.  
2. public class Countdown : MonoBehaviour
3. {
4.     public float timer;
5.     public float timerLimit = 30.0f;
6.     public GUIText timerText;
7.     public string clockName;
8.  
9.     public void SetTimerText(){
10.         timerText.text = string.Format("{0}: {1}", clockName, timer.ToString());
11. }
12.  

This is my best guess with the code provided. I'm assuming that ObjectTimer has something in its constructor that handles some setup.

 

Hey there JT,


Thank you for that info,


Sorry I forgot about that ObjectTimer one. Here goes;

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using System.Collections.Generic;
4.  
5. public class ObjectTimer
6. {
7.  
8.  
9.         public string name;
10.         public int time;
11.         public bool isStarted;
12.         public int newTime;
13.        
14.         public ObjectTimer(string newName, int NewTime)
15.         {
16.             name = newName;
17.             time = newTime;
18.             isStarted = false;
19.         }
20. }

 

Sorry. There's a lot of gaps in your code and I'm going to have to make some assumptions to be of any use. What you need to do is grab a reference of one of the ObjectTimers in your objectTimers list, assign that to coutndown, and use that reference for displaying info. Currently I can't see how anything is interacting, or where you objectTimer list lives, and that's what is important. Here's a hint though without going into too much detail, and not incorporating your list at all.

Also I'm ignoring the use of timerLimit because I don't fully understand what you're trying to do with it. You create a random amount of time but then you cap it at 30 seconds. The below script will create you a timer at 120 seconds and when it is fully counted downit print Game Over. At any time you can replace Countdown.Timer with a new ObjectTimer instance and it'll just keep on truckin' with that new timer.

Code (CSharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class Countdown : MonoBehaviour
6. {
7.     public static ObjectTimer Timer;
8.     public GUIText timerText;
9.  
10.     // Use this for initialization
11.     void Start]()
12.     {
13.         Timer = new ObjectTimer("Alarm", 120);
14.     }
15.  
16.     // Update is called once per frame
17.     void Update()
18.     {
19.         Timer.time -= Time.deltaTime;
20.         SetTimerText ();
21.         if (Timer.time <= 0.0f)
22.         {
23.             // This will spam your console with Game Over, btw.
24.             print("GAME OVER!");
25.         }
26.  
27.     }
28.     public void SetTimerText()
29.     {
30.         timerText.text= string.Format("{0}: {1}", Timer.newName, Timer.time);
31.     }
32. }
33.  
34.  

So, in a different script you could generate your list of timers (or this script, actually) and then randomly choose one to assign to the static Timer variable.

I hope that does what you want.
