Create GameObject(Sprite) at Runtime

Question

Hello everyone, so I'll cut to the chase. The idea for the script is the next:

 void Update
  {
    If(gameObjectCount < 5){
        //Create GameObject with certain properties.
     }
  }

Now I come to ask you people this because Im new to Unity and I'm getting the hang of it. 1.As for the logic, my concern is, where would I attach the script that manages the Game's Runtime? In this case the constant update on the scene. 2. As for the actual question, how do I manage to create the gameObject as child of another GameObject I've created?(For example an enemy that uses certain sprite Animations and certain script that makes it move?

I hope I don't take much of your time while reading/answering this questions.

have a great day!

The usual approach to spawn Objects at runtime is using Instantiate, you can also save the instantiated object in a List, which gives you a reference to each object created and the amount of objects that has been instantiated. Like this:

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 
 public class GameController : MonoBehaviour {
     public GameObject object2Spawn;
     private List<GameObject> spawnedObjects = new List<GameObject>();
     public int maxSpawns = 5;
     public float secondsBetweenSpawns = 5.0f;
     private float nextSpawnTime = 0;
 
     void Update()
     {
         if (Time.time > nextSpawnTime && spawnedObjects.Count< maxSpawns)
         {
             GameObject instantiatedObject = Instantiate(object2Spawn, transform.position, transform.rotation);
             spawnedObjects.Add(instantiatedObject);
             nextSpawnTime = Time.time + secondsBetweenSpawns;
         }    
     }
 
 }

Note that this code is not tested.

@$$anonymous$$ii Any empty GameObject would work, what this script does is spawn "object2Spawn" at the position of the GameObject this script is attached to.
