Question by RoganEM · Sep 26, 2019 at 04:06 PM · gameobjectinstantiateprefabobjectscene

How to Reference Player when Instantiating Prefab

Hello, I have created a car by using the default Unity Al with my own police car model on top. I have made a prefab of t$$anonymous$$s car and I am trying to instantiate it into my scene. The instantiation works, but the problem occurs when I try to make it follow my player. The car just stays in one spot and does not$$anonymous$$ng. I have looked in the Inspector and when a new ve$$anonymous$$cle is instantiated, it has no references to my player. I understand prefabs cannot keep references to objects in a scene but is there another way around t$$anonymous$$s? If there is a way, could somebody explain t$$anonymous$$s to me. as I am new to Unity and know only the basics. Thank you.

You need to add a reference to the Player in a script of your freshly instantiated GameObject. You can do it from the instantiator script or from the instanciated one.


From the instatiator class

 using UnityEngine;

 class ClassW$$anonymous$$chInstantiatePrefab : MonoBehaviour
 {
     public GameObject Prefab;
     private Player _player;
 
     private void Start()
     {
         // You may need a different logic here to retrieve
         // the Player, change it to fit your needs.
         _player = GetComponent<Player>();
     }
 
     public void MethodW$$anonymous$$chInstantiatePrefab()
     {
         var go = Instantiate(Prefab);
         var component = go.GetComponent<YourComponent>();

         component.Player = _player;
     }
 }


From the instance class

 class MyClass
 {
     private Player _player;
 
     private void Start()
     {
         _player = FindObjectOfType<Player>();
     }
 }
