        purple = null;
        red = null;
        yellow = null;
        FindItemsObjects ();
    }

When I debug.

Debug.Log (blue); it gives me null, but in WhenYouDoSomething function when I debug Debug.Log (itemTransforms); it gives me the object with name line.

Why that transform is not assigned to blue ? or anyotherTransform that I declared?

Hello,

try changing the function declaration to this:

public void WhenYouDoSomething(GameObject item, out Transform itemTransforms, Vector3 itemScale)

Similarly, you will have to call the function like this:

WhenYouDoSomething (_blue, out blue, blueScale);

This way you’re passing the variable to the function by reference and not by value.
