Problem With Spawning Enemy Prefab?

I have created a spawner that spawns clones of my enemy prefab the problem i face is that i have the enemy moving towards my object of choice but when they spawn they do not move towards the object. if i place them in the scene and apply the object for them to target they start moving towards it perfectly but they do not from the spawner here is what happens.

And here is my code for moving towards the chest

Code (csharp):

1. var target: Transform;
2. var startTime;
3. var timer1: int;
4. var timingOn: boolean;
5. var GetReadyButton: boolean;
6. var font : Font;
7.  
8. function Start()
9. {
10.    
11. }
12.  
13. function Update()
14. {
15.    if(Input.GetButton("StartWave"))
16.    {
17.       timingOn = true;
18.       startTime = Time.time; //time starter
19.      
20.    }
21.    
22.    if (timingOn)
23.    {
24.       TimerStart();
25.    }
26.    
27.    if(!target)
28.    {
29.  
30.       target = GameObject.FindWithTag("Chest").Transform;
31.       return;
32.    }
33. }
34.  
35. function OnGUI ()
36. {
37.    GUI.skin.label.font = font;
38.    GUI.Label (Rect (400, 40, 100, 20),"Press G To Start"); //First Text to tell player to press g to start
39.    
40.    if(Input.GetButton("StartWave"))
41.    {
42.       GetReadyButton = true;
43.    }
44.    
45.    if(GetReadyButton)
46.    {
47.       GUI.Label (Rect (415, 55, 100, 20),"10 Seconds");
48.    }
49. }
50.  
51. function TimerStart()
52. {
53.    timer1 = Time.time;  //Set time
54.  
55.    if(timer1 - startTime >= 10)
56.    {
57.       //Debug.Log ("Timer finished, spawn now");
58.       GetComponent(NavMeshAgent).destination = target.position;
59.       //target = GameObject.FindWithTag("Chest").Transform;
60.      
61.     }    
62. }

I Hope someone can fully solve this because i have been stuck on this for awhile now :/

Thank you

 

Well, as far as I can tell, this seems to be the problem:

Code (csharp):

1.  
2.    if(!target)
3.  
4.    {
5.  
6.       target = GameObject.FindWithTag("Chest").Transform;
7.       return;
8.  
9.    }
10.  

Did you try to use debug.log or print to see if this if-statement runs through? It seems like it should, and I'm going to guess that the problem lies with the FindWithTag. Check if the Chest has the "Chest" tag.

Also, try GameObject.Find("Chest") just in case. It may also just be "easier" and more specific, although it does have its disadvantages.
