I want to use the tween prototype in a custom class that extends MovieClip. I am already including “lmc_tween.as” in my root and I have already replaced the “MovieClip.as” file in my flash directory with the one from the shared/Zigo directory. However, I still get compiler errors if I try to include “lmc_tween.as” in the class file, or without the include in the class it will compile but the tween prototype will not work in the custom class. Does anyone know how to fix this? :huh:
