Why is not assigning new value ?

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.
The out parameter `itemTransform' must be assigned to before control leaves the current method
this is the error Im getting
k, changing from out to ref, solved the problem THAN$$anonymous$$ YOU!
Add itemTransforms = null in the first if branch like this:
if (item == null)
{
Debug.Log ("Item is null");
itemTransforms = null;
}
Variables with out parameters must always be assigned a value in a function and in your version this was not the case because you only assigned it a value in the else branch.
