c# I have a drag script that doesnt work on spawned objects!

Hi,
I have a script that allows me to drag the object with my mouse when i hover over it.
It perfectly works with a normal object in the scene, but when I try to spawn a prefab with the script attached I cant drag it!
Where is my mistake? Thanks for every answer

Here is the code:

Drag Script:

Code (csharp):

1.  
2.     private Vector3 screenPoint;
3.     private Vector3 offset;
4.  

continues here:

Code (csharp):

1.  
2.         void OnMouseDown()
3.         {
4.             screenPoint = Camera.main.WorldToScreenPoint(gameObject.transform.position);
5.  
6.             offset = gameObject.transform.position - Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z));
7.  
8.         }
9.  
10.         void OnMouseDrag()
11.         {
12.             Vector3 curScreenPoint = new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z);
13.  
14.             Vector3 curPosition = Camera.main.ScreenToWorldPoint(curScreenPoint) + offset;
15.             transform.position = curPosition;
16.  
17.         }
18.  

and here is the important section of the spawn script:

Code (csharp):

1.  
2.     void SpawnObject()
3.     {
4.         Instantiate(Steak, SteakSpawner.position, SteakSpawner.rotation);
5.     }
6.  

 

Does your spawned object have a collider? Is it an exact prefab of the object in your scene?

 

yes it has a collider and it has the script attached, but it doesnt work

 

I mean, if it's an exact copy, then it should work. I would say make sure nothing is blocking it. Add some debug.log messages to your OnMouseDown to see if it's registering, same with the drag.
