60 second timer

Unity Engine
1

I am trying to create a 60 second timer. Here is my code. When I play my game it gives me a decimal, but I want a whole number. Please help!

using UnityEngine;
using TMPro;
using UnityEngine.SceneManagement;


public class Timer : MonoBehaviour {

    public TMP_Text timer;
    public float timerValue = 60f;


    void Update()
    {
        timerValue -= Time.time;
        timer.SetText(timerValue.ToString());
    }

  


}

Check out the C# docs for the .ToString() method… you can optionally supply a string formatting argument to force it to only render as integers, or put commas, or whatever else.

I don’t understand. Can you please give me a line of code so I can understand.

This explains how standard numeric format strings work, and has several examples of how to use them:

But in this case, you’d probably be better off explicitly converting the float to an int before doing anything else, because that way you can add in a condition that prevents ToString from being called at all if the int is the same as last frame. This will prevent a lot of unnecessary memory allocation.

Your code also uses Time.time where I’m pretty sure you meant Time.deltaTime.

Putting a single hash in ToString(“”) outputs it to that - result is no decimals and a whole number

timer.SetText(timerValue.ToString("#"));
