How to turn an int into a gameobject?

Unity Engine

Firstly, how to post code tags: Using code tags properly

Instantiate returns the newly created instance. You can use this to modify it after its been created, and hold onto a reference to it for as long as you need.

So for example:

public class CarSpawnScript : MonoBehaviour
{
    public GameObject[] carPrefabs;

    public float speed = 2;
   
    public Transform waypoint;

    private GameObject carInstance;

    private void Start()
    {
        int prefabCount = carPrefabs.Length;
        int index = Random.Range(0, prefabCount);

        GameObject prefab = carPrefabs[index];
        carInstance = Instantiate(prefab, transform.position, Quaternion.identity);
    }

    private void Update()
    {
        Vector3 currentPosition = carInstance.transform.position;
        Vector3 newPos = Vector3.MoveTowards(currentPosition, waypoint.position, speed * Time.deltaTime);
        carInstance.transform.position = newPos;
    }
}

Few things I adjusted and will point out:

  • We store our prefabs in an array, which we can assign to via the inspector
  • We use the length of the array to not have to hard code a random index
  • Then we hold onto the instanced car so we can use it between Start and Update, and move said instance
