Confused about NVL-Mode works with defining character.

[Two Dollars]

I am fairly new to Ren'py and have not used NVL-mode before. But I want to use Nighten's Yet Again phone system. I've watched and read the tutorials but had a question about defining characters.

Here is how I have my characters defined currently.

define MC_Name = Actor(Character("Alena Burke", color = "#FF0044"), "Alena Burke", 0, 0, 100, 60, 70, 80, 60)
define adrian = Actor(Character("Adrian Dragotta", color = "#0033FF"), "Adrian Dragotta", 50, 100, 80, 10, 50, 10, 100)
define nicky = Actor(Character("Nicky Hasagawa", color = "#0033FF"), "Nicky Hasagawa", 100, 25, 100, 100, 90, 100, 100)

If I want to use them in NVL-Mode do I just change them to this?

define MC_Name = Actor(Character("Alena Burke", kind = nv1, color = "#FF0044"), "Alena Burke", 0, 0, 100, 60, 70, 80, 60)
define adrian = Actor(Character("Adrian Dragotta", kind = nv1, color = "#0033FF"), "Adrian Dragotta", 50, 100, 80, 10, 50, 10, 100)
define nicky = Actor(Character("Nicky Hasagawa", kind = nv1, color = "#0033FF"), "Nicky Hasagawa", 100, 25, 100, 100, 90, 100, 100)

I was also a little confused about the whole NVL_clear command and how to get in and out of NVL Mode.

Thank you,
