How do you address a named instance of a movieclip from the class file of the movieclip?

Question

I have a movieclip instance named 'placeholder' on the canvas, and I want to change the alpha of the named movieclip from it's class without effecting the alpha of all the movieclips of the same type. How would I specifically target the named movieclip instance that is on the canvas?

Answer 1

Just use the script:

placeholder.alpha = someValue;
