Instantiate Terrain Object as child of Empty Game Object

Question

I realise this has been asked many times already, but I've just come from FOUR other threads with similar titles, tried what they said, and couldn't get it to work.

I have a script attached to an empty Game Object (with box collider attached). I want to instantiate a terrain piece as a child of the object.

So far I have:

 var tile;
 
 tile = Instantiate (fHigh1, Vector3(r, 0, c), transform.rotation);
 
 tile.transform.parent = this;

A multitude of different errors pop up with every combination I try. I've also tried:

 tile.transform.parent = transform;
 tile.transform.parent = Transform;
 tile.Transform.parent = transform;
 tile.Transform.parent = Transform;
 tile.transform.this = transform;

Help please :(

I would think your error is there:

 tile.transform.parent = this;

'this' represents the script not the object.

try

 tile.transform.parent = transform;

The code below works for me (in C#):

 public class Script : MonoBehaviour {
     public GameObject tile;
     void Start () {
         GameObject obj = (GameObject)Instantiate(tile,new Vector3(0,0,0),Quaternion.identity);
         obj.transform.parent =transform;
     }
 }

Note: Since you are using UnityScript, if you have #pragma strict at the top var tile; should be var tile:GameObject;

 var tile :  GameObject ;
 tile = Instantiate (fHigh1, Vector3(r, 0, c), transform.rotation);

Throws error: "BCE0022: Cannot convert 'UnityEngine.Transform' to 'UnityEngine.GameObject'."

And as you read above, I already tried:

 tile.transform.parent = transform;

With no success. :( Perhaps it is in fact:

 tile.transform.parent = transform;

but I have to fix the other issue first?

Also, I don't know C# yet. XD

You may have different type of variables, so to make it simple just make them all GameObject:

 var obj:GameObject;
 var tile:GameObject;
 function Start () {
     tile = Instantiate(obj,Vector3(0,0,0),Quaternion.identity);
     tile.transform.parent =transform;
 }

I did what you said and played:

InvalidCastException: Cannot cast from source type to destination type. tileCollider.OnTriggerEnter (UnityEngine.Collider other) (at Assets/Scripts/tileCollider.js:57)

A preview:

var tile : GameObject; var fHigh1 : GameObject;

 function OnTriggerEnter ( other : Collider )
 {
 r = other.transform.position.x;
 c = other.transform.position.z;

 
 if ( other.gameObject.name == "fHigh1")        
 {
 tile = Instantiate (fHigh1, Vector3(r, 0, c), Quaternion.identity);
 }
 
 tile.transform.parent = transform;
 
 }

Note the other.gameObject.name is referring to a DIFFERENT "fHigh1" object.
