Hello, I'm trying to create a short 2D game where you can wait x amount of time to get for example 50 "troops". This for now works fine, but now I need a script that detects the number of troops I have (at the startpoint) and send them out, just like small dots going from start point to an endpoint, but not one after another more like 5 in a row * 10.

Troops are counted upwards every second with a float, so could we use that or do I need something other for that?

What I have tried:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class TroopsPerSecond : MonoBehaviour
{
    public Text troopText;
    public float troopAmount;
    public float troopIncreasedPerSecond;

    // Start is called before the first frame update
    void Start(){
        troopAmount = 0f;
        troopIncreasedPerSecond = 10f;
    }

    // Update is called once per frame
    void Update(){
        if (troopAmount < 50f){
            troopAmount += troopIncreasedPerSecond * Time.deltaTime;
            troopText.text = troopAmount.ToString("F0");
        }
        else{
       print("Troops full");
       }
    }
}
