Create CountDown Timer (3d Text) in C#

I was hoping someone could lend their advice, I'm relatively new to coding and would appreciate the input. I was combing the forum and found a countdown script that works quite well when applied to a 3d text. I was just wondering how to expand it in the following ways:

1) At 0 seconds, it should stop the timer and display a message
2) At fixed intervals (arbitrary) it can prompt a message

The script is the following:

using UnityEngine;
using System.Collections;

public class Timer : MonoBehaviour {
public float time = 20.0f; // Arbitrary number
TextMesh tm;

void Start () {
tm = GetComponent<TextMesh>();
}


void Update () {
time -= Time.deltaTime;
tm.text = Mathf.RoundToInt(time).ToString();
}
}

Thank you in advance!

 

Code (CSharp):

1. void Update () {
2.     time -= Time.deltaTime;
3.  
4.     if(time > 0){
5.         //If time is greater than 0, display time left
6.         tm.text = Mathf.RoundToInt(time).ToString();
7.     }else{
8.         //Otherwise display this
9.         tm.text = "Time is up!";
10.     }
11.    
12. }

 

Awesome, thank you very much!

As an aside, do you have any advice for delaying the countdown until prompted to begin again? Another script will be responsible for triggering this. Again, thanks in advance!

 

Do you mean a means to restart the timer, or to pause it and resume it when you wish?

 

To pause and resume it

 

Code (CSharp):

1. bool paused = false;
2.  
3. void ToggleTimer(){
4.     paused = !paused;
5. }
6.  
7. void Update () {
8.     if(!paused){
9.     //If not paused
10.         if(time > 0){
11.         //If time is greater than 0, display time left and reduce time
12.         time -= Time.deltaTime;
13.         tm.text = Mathf.RoundToInt(time).ToString();
14.         }else{
15.         //Otherwise display this
16.         tm.text = "Time is up!";
17.         }
18.     }else{
19.         //If paused, don't reduce time and display a paused message
20.         tm.text = "Timer paused";
21.     }
22. }

You would have to use some way to run the ToggleTimer(); function, maybe pressing a certain key? For R for example:

Code (CSharp):

1. if(Input.GetKeyDown(KeyCode.R)){
2.     ToggleTimer();
3. }

 

I'm getting a few errors. Could you please copy/paste the whole code just to make sure I'm not missing something? Thanks

 

Just paste the errors instead and I'll help you sort them out

 

One side note: Rather than using Mathf.RoundToInt, I recommend learning to use string.Format, ToString(string), and string formatting codes in general - this is exactly what they're made for, they're usually more efficient, and you'll get a lot more versatility.

 

As someone who is somewhere in between beginner/intermediate in programming, how would int.Parse rank in terms of efficiency?

 

It's.... not related? int.Parse turns a string to a number, you're turning from a number to a string.

 

Yes, you are quite right. I was off somewhere, mentally.

 

Well whenever I press R while previewing, nothing happens, it just keeps counting down. As for the GetKeyDown if statement, is this where I would reference the other script that triggers either the countdown or pause?
