Problem with code

I have this code

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class spawn : MonoBehaviour {
5.  
6.     public Transform[] spawnPoint;
7.     public GameObject tnt;
8.     public int Level = 1;
9.     public int a = 0;
10.     public int score = 0;
11.  
12.     public float offsetY = 40;
13.     public float sizeX = 100;
14.     public float sizeY = 40;
15.     public float delay;
16.  
17.     public Transform Count3;
18.     public Transform Count2;
19.     public Transform Count1;
20.     public Transform CountGo;
21.     public Transform CountSpawn;
22.  
23.     // Use this for initialization
24.     void Start () {
25.         Time.timeScale = 0;
26.         InvokeRepeating ("SpawnTNT", 4, delay);
27.     }
28.    
29.  
30.     void Update () {
31.    
32.         if (a > 10) {
33.             if(delay > 0.3F){
34.             delay *= 0.9F;
35.             a=0;
36.             Level++;
37.            
38.             }
39.         }
40.     }
41.  
42.     void SpawnTNT ()
43.     {
44.         int i = Random.Range (0, 5);
45.         Instantiate (tnt, spawnPoint [i].position, Quaternion.identity);
46.         a++;
47.     }
48.  
49.     void OnGUI()
50.     {
51.         GUI.Box (new Rect (Screen.width / 2 - sizeX/2, offsetY, sizeX, sizeY), "Score: "+score);
52.     }
53.  
54.     void addScore ()
55.  
56.     {
57.         score++;
58.     }
59.  
60.     void Go ()
61.     {
62.         Time.timeScale = 1;
63.         Invoke ("SpawnCount3", 0);
64.     }
65.  
66.     void SpawnCount3()
67.     {
68.         Instantiate (Count3, CountSpawn, Quaternion.identity);
69.     }
70. }
71.  

And im getting these errors

Code (CSharp):

1. Assets/scripts/spawn.cs(68,17): error CS1502: The best overloaded method match for `UnityEngine.Object.Instantiate(UnityEngine.Object, UnityEngine.Vector3, UnityEngine.Quaternion)' has some invalid arguments
2.  
3.  
4. Assets/scripts/spawn.cs(68,17): error CS1503: Argument `#2' cannot convert `UnityEngine.Transform' expression to type `UnityEngine.Vector3'
5.  
6.  

 

CountSpawn is a Transform, you need a position (Vector3).

Code (csharp):

1. Instantiate(Count3, CountSpawn.position, Quaternion.identity)

Edit: This was misleading/incorrect, so struck out.
Note, you're instantiating a transform there, is that what you want? (Count3 is a transform) did you want to instantiate a GameObject or a Transform? I expect you want a GameObject.

 

Should still work as a Transform iirc.

 

This page:

http://docs.unity3d.com/ScriptReference/Object.Instantiate.html

indicates that there are only two overloads to Instantiate, neither takes a transform.

 

I'm pretty sure that @LaneFox is correct. The two overloads both take Object, which I assume both Transform and GameObject both inherit from.

From that link (emphasis mine):

If you are cloning a GameObject then you can also optionally specify its position and rotation (these will default to Vector3.zero and Quaternion.identity respectively). If you are cloning a Component then the GameObject it is attached to will also be cloned, again with an optional position and rotation.​

As such, Transform is a Component (inherits from) and therefore it will clone the attached GameObject also (but I assume it still returns (correctly) a reference to the Transform and not the cloned GameObject, but the GameObject can be got from transform.gameObject, etc).

I've amended my previous post to remove my misleading/incorrect statement.
