Hi Blaze,

Welcome back to our community!

Rigidbody rb; is a declaration (and definition) of a variable. In C#, all variables require a name and a data type. Here, the type is Rigidbody. Then the variable is able to hold a reference to an object of type Rigidbody. Otherwise, its default value is null (= no object reference).

In line 22, your code assigns a reference to the rb variable, given GetComponent returns an object.

Did this clear it up for you?

Yes i get but i have one more question
This Is also a valid statement for C#

Void start
{
rigidbody rb = GetComponent();
}
so can we declare and reference at the same time in start

[Nina]

Yes, that’s right. In your example, the rb variable gets declared within Start, and an object reference gets assigned in the same live if GetComponent returns a reference.
