Transform.position not changing

Hello!
I want to read in the position of my player. It is a prefab and will be spawned then starting the Game at the position (0|0|0). Now, in the script of the EnemyKI (AI) I want to read in the position of the player. The problem is, that the position is not updating then reposition the player.
Hope you can help me!
Here my script:

Code (C#):

1.  
2. using System.Collections;
3. using UnityEngine;
4.  
5. public class EnemyAI : MonoBehaviour  {
6.     public GameObject target;
7.     public float moveSpeed;
8.     public float rotationSpeed;
9.  
10.  
11.     void Start() {
12.         target.transform.position = new Vector3 (0, 0, 0);
13.  
14.         Debug.Log (target.transform.position);
15.  
16.  
17.     }
18.  
19.  
20.  
21.  
22.     void Update() {
23.         Debug.DrawLine (transform.position, target.transform.position);
24.  
25.         Vector3 pos = target.transform.position;
26.         Debug.Log (pos);
27.     }
28.  
29.  
30. }
31.  

I dragged the player prefab into the field in the inspector.

 

What are you expecting to happen?

 

I want the position witch is wirtten on the console to update then I change player position. Later I want to use the player position to let the enemy chase the player

 

Currently you're forcing

target

to 0,0,0 and logging that vector to the console. That's pretty much it. It's repeating 0,0,0 in the console because you've told it to do exactly that.

If you expect something else to happen, you should probably write some more code to facilitate that.

 

But In the Update loop I rewrite the position to the console. So why the position is ever (0|0|0)? I am moving the Player!!!

Code (C#[ using System.Collections; using UnityEngine; public class EnemyAI : MonoBehaviour { public GameObject target; public float moveSpeed; public float rotationSpeed; void Update() { Debug.DrawLine (transform.position, target.transform.position); Vector3 pos = target.transform.position; Debug.Log (pos); } } [/Code):

1.  

 

Because you are pointed at the Prefab, not the Scene Object.

 

And how to get the Object in the game?

 

One easy way of doing that is reference the scene player in your enemy spawning script.
When any enemy is spawned, pass the reference to the newly instantiated enemy.

 

Can you show me that in code please?

 

You should really consider doing some beginner tutorials, because I explained it simply.
It would look something like this.

Code (csharp):

1. public GameObject enemyPrefab;
2. public GameObject target; // player
3.  
4. void SpawnEnemy() {
5.    GameObject go = Instantiate(enemyPrefab);
6.    go.GetComponent<EnemyAI>().target = target; // assign the reference from here to there.
7.  }

Something like that.

 

But the reference to the player is the same. I am drag and drop the prefab to the script. What is the difference between yours and mine? Or is it only working from Objects witch are on the Herachy?

 

No, no.. I assume the game object that spawns the enemies is in the scene when you begin. I also assume that the player, too, is in the scene. You would drag the player from the hierarchy to this variable.

 

No. My player is a prefab and will be instantiated by a player spawning script

 

Well, is the player spawning script/object in the scene when it starts, along with the enemy script that spawns?

 

I've got a GameObject in my Scene witch hold a script for enemy, and player spawning.

 

Okay then, so to elaborate on my earlier example with a small modification:
the player spawning script has a reference to the enemy script.
the player spawning script spawns the player and retains the reference.
- script passes the newly made reference to the enemy spawner

the enemy spawner instantiates enemies and passes the reference of the player in the scene along to them.

This is just one way. Does it make sense now?

 

But how to get the reference of the player? Its a prefab.

 

So, when it spawns the player from the prefab, it stores the instantiated copy in a variable. Uses that to pass along...

 

Ahhh And I pass this Object to the Enemy spawner script and this passes it to the enemyAI script?

 

Exactly...

 

But before I wanted to rewrite the AI, its works with GameObject.FindGameObjectWithTag("Player"). But now it doesn't work anymore.
But thank you for your help

 

Sure, tag would work. I couldn't understand from your latest reply what doesn't work anymore, but hopefully you can figure out which one to use.
I prefer to avoid using 'Find', whether by tag or name, but the option is always there.

 

Okay Thank you very much.
But what to do then I've got more then one player? (In my case a fleat of spaceships)

 

Well, then you'd have a list of players the enemy might be interested -- limited perhaps by threat* or proximity or some other value/variable. If that's what you meant..

edit: fixed typo.

 

Hmmm I don't know. But thank you for your help.

 

So what exactly is the solution ? How can I update the transform of a gameObject that is instantiated from a prefab and print out every single point when im moving it ? I am trying to use bounds.contains but it does not update the position of the prefab, it just stucks at the instantiation position even when its in Update(). How can I update and print the exact position of a gameObject which is instantiated whenever it moves?

 

Solution: the only solution I found is to duplicate which over object your trying to apply the transform to and delete the old one.

explanation: its not a issue cause you're doing something wrong.. its some internal issue which causes the transform of that specific object to be immune to any changes through scripts. I wasted hours on it before realizing there is nothing wrong with my code its just Unity had a screw lose somewhere internally causing this problem,

 

FOR ANYONE WHO IS STRUGGLING WITH THEIR GAME OBJECT SUDDENLY NOT BEING MOVEABLE:

I couldnt find this almost anywhere online, but for me this issue was caused by the animator. Try disabling the animator and see if you can move now. If you can, then there is at least one animation in which the game object as a whole (not individual bones) is moved/translated. Delete or change the animations and it should let you move now

 

I think u can't instantiate the objectPrefab on Inspector if u want get the current position each time.

So, i used FindObjectOfType<T> the Type is the name of the script attached the Player :

Code (CSharp):

1. private Transform _targetPos;
2.  
3. private void Awake()
4. {
5.    _targetPos = FindObjectOfType<PlayerController>().GetComponent<Transform>();
6. }
