Get vector3 from another script (38228)

Hey guys.

I’m having some problems with getting a vector3 variable from another script.

public Vector3 krudtPosition;

In Update(), I’m running this next script through once, using a bool checking if it has just been done.

krudtPosition = new Vector3(30.50F,krudt.transform.position.y,krudt.transform.position.z);

This works fine when I debug it. The problem comes when I want to get it in another script.

First I define this.

public Grid krudtScript;

Grid is the name of the script where I want to get the vector3 from.

Then, in the Start() i do the following:

public GameObject krudt;
GameObject theKrudt = GameObject.Find("Krudt");
krudtScript = GetComponent("Grid") as Grid;

And lastly, I’m using it like this:

krudt.transform.position = krudtScript.krudtPosition;

I’ve also tried this, but to no luck:
krudt.transform.position = new Vector3(krudtScript.krudtPosition);

I’m getting this error:
NullReferenceException: Object reference not set to an instance of an object

That's simply because you implicitly use:

this.GetComponent()

instead of

theKrudt.GetComponent()

So you search for this script on the gameobject this script is attached to and not on the other where it actually is.
