Question by RandomUser123 · Sep 20, 2014 at 09:09 PM · instantiatebuttonclone

Having an issue with instantiating objects on button clicks

Theres a button in my scene and I want to instantiate an object when I press it but it returns the error:

 Type IPointerClickHandler expected Button received. i:0. The variable bullet of helicopter has not been assigned.
 You probably need to assign the missile variable of the helicopter script in the inspector
 
 public Rigidbody bullet;

 public void fire()
     {
         Rigidbody clone;
         
         clone = Instantiate(bullet, transform.position, transform.rotation) as Rigidbody;
         clone.velocity = transform.TransformDirection(Vector3.forward * 10);
     }

I have the bullet prefab on my object in the inspector and my button uses the function above when clicked so I don't know what the problem is, if anyone could help, I'd appreciate it

change the code to:

 public GameObject bullet;
 
 public void fire()
 {
  GameObject clone;
  
  clone = Instantiate(bullet, transform.position, transform.rotation) as GameObject;
  clone.rigidbody.velocity = transform.TransformDirection(Vector3.forward * 10);
 }

you may need to delete and recreate the button in the scene for some reason to get it to work.
