How to increase Value of for example "gold" every second?

Question

Hello, thank you for taking time for my question!

I want to create a small game that has a small simple economy. Every second, for example, the value ' Gold ', which is represented as text, has to be increased by 1 every second.

I imagine this:

At the top left corner is ' Gold: 15 '

After that, the value ' 15 ' should be counted up every second.

Would anyone have a C# script for me please?

 using UnityEngine;
 using UnityEngine.UI;
 
 public class GoldManager : MonoBehaviour
 {
     public int GoldValue = 15;
     public int Power = 5;
     public int DelayAmount = 1; // Second count
     public Text GoldValueText;
     public Text PowerText;
 
     protected float Timer;
     
     void Update()
     {
         Timer += Time.deltaTime;
 
         if (Timer >= DelayAmount)
         {
             Timer = 0f;
             GoldValue++; // For every DelayAmount or "second" it will add one to the GoldValue
             GoldValueText.text = "Gold value: " + GoldValue;
                     PowerText.text = "Power: " + Power;
         }
     }
 }

By now you should get the main idea, giving code is not the best way to learn all the time but it'll be enough for now :)!

Just how can I change the text "Gold value: " For example to "power: ". I just tried this in the script, but it doesn't work:

GoldValueText.text = "Power: " + GoldValue;

What is power going to be? If it is going to be a number that is going to contain decimal place use float, if not use int. I am going to use integer (int). outside of the update() function make a variable, in your case I'd do

 public int GoldValue = 15;
 public int Power;

The same as the text, this is displayed:

Gold Value: 15

But I want to know if I can change this so easily for example to power Volue: 15.

So I tried to change it from

GoldValueText.text = "Gold value: " + GoldValue;

to

GoldValueText.text = "Power: " + GoldValue;

This is one of the simplest things, but somehow something is bewitched.

 if (Timer >= DelayAmount)
     Timer = 0f;

is better as:

 if (Timer >= DelayAmount)
     Timer -= Timer;

or you're throwing away the surplus every time the code executes the block

What you can do is have a timer that increments a gold value every second.

Script:

 public int goldValue = 15;
 
 private float timer = 0f;
 public float delayAmount;
 
 void Update()
 {
    timer += Time.deltaTime;
 
    if (timer >= delayAmount)
    {
       timer = 0f;
       goldValue++;
    }
 }

You can preset your custom delay amount e.g. 1.0f in the editor.

You can also use Coroutines, but I feel that this is a more efficient and simpler option.

No problem! This is untested, so I hope it works too. :)

$$anonymous$$ay you please mark this as the definite answer if it does work? Thank you!

Can you tell me how to apply this script? Where do I put it? And how can you use Goldvalue if you didn't tell the script what it is and where it is?

Sorry, I'm a layman in program$$anonymous$$g. So apologies for those stupid questions.

The selected answer works, but I would much prefer a Coroutine in this situation, especially when you are dealing with time. Also great in terms of maintainability and readability.

     private int GoldValue = 15;
     private float TimeSeconds = 1;
 
     private void Start() {
         
         StartCoroutine(SpawnTimer());
     }
 
     private IEnumerator SpawnTimer() {
         
         while (true) {
             yield return new WaitForSeconds(TimeSeconds);
             GoldValue++;  
         }
     }
