Question when i spawn an enemy through a prefab, my script for movement isnt working

when i spawn an enemy through a prefab, my script for movement isnt working , the prefab is all set up but the new spawned enemys just go to the centre of the spawner. very new to unity so pls respond with caveman english

this is the movement script
public class AiEnemyMovement : MonoBehaviour
{
[SerializeField] private GameObject player;
public Rigidbody2D rb2d;
public float speed = 2;
// Start is called before the first frame update
void Start()
{

}

// Update is called once per frame
void Update()
{

}

void FixedUpdate()
{
transform.position = Vector2.MoveTowards(transform.position, player.transform.position, speed * Time.deltaTime);
}
}

 

Hey and welcome to the forums. Please use code tags next time you post code tho

When you are not sure what is going on in a problem, start by printing some information using Debug.Log!
https://docs.unity3d.com/ScriptReference/Debug.Log.html

You already established that some movement happens. This means the script is being executed. This also means that the speed part is not the problem. So it must be a problem with one of the two positions. Your own position (transform.position) wont ever be unavailable, so the only thing left is player.transform.position. By printing its value, you will gain new information. You will then likely find out that it's not what you think it is.
The above roughly represents the line of thought you should have when approaching a problem.

A prefab can only reference things within it, so unless player is part of the prefab, i'd assume it's not set.

Also, this got nothing to do with your problem, but you dont want to put anything that is not physics into FixedUpdate. I could go into depth, but since Unity tries to make sure FixedUpdate actually gets called on fixed intervals, every bit of slowdown in there causes exponential slowdown to the actual framerate (Update) of your game. A few lines of code here or there wont make a difference, but it's a habit you shouldnt get into, which is why i mention it.

 

thanks yoreki!
