Hi, I changed the thread, edited some…

So i have an external as file which have a function. the function make the movie clip do something when it hit another object which i named “block.”

but the external as file can’t accses “block” movie clip which’s added from the fla files and given an instance name as “block”.

FYI, the as file is attached to a movie clip.
