Value

Hello, I am currently working on a "Cookie Clicker" and I have a problem with this project. and I would like, if I buy a "human" one time, that the value in the script increases (every time I buy another person). Here is the script that gives the player the money after a while:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5.  
6. public class Points : MonoBehaviour
7. {
8.     public Text PeopleAmount;
9.     public Text scoreText;
10.     public float peopleCounter;
11.     public float scoreAmount;
12.     public float pointIncreasedPerSecond;
13.     public float ShopWithDraw;
14.  
15.     void Start()
16.     {
17.         scoreAmount = 15f;
18.         pointIncreasedPerSecond = 0.0f;
19.     }
20.  
21.     void Update()
22.     {
23.         scoreText.text = "" + (int)scoreAmount;
24.         scoreAmount += pointIncreasedPerSecond * Time.deltaTime;
25.  
26.         if (scoreAmount > PlayerPrefs.GetInt("Highscore"))
27.         {
28.             PlayerPrefs.SetInt("Highscore", (int)scoreAmount);
29.         }
30.     }
31.  
32.     public void WithdrawCurrency()
33.     {
34.         if (scoreAmount >= 15)
35.         {
36.             Debug.Log("siis0");
37.             scoreAmount -= 15;
38.             peopleCounter++;
39.             PeopleAmount.text = "" + (int)peopleCounter;
40.         }
41.     }
42. }
43.  

 

Couldn't really look for my problem either, because I have no idea what to call it.
