ok, so ive been looking around and found out how to get my mp3's on, have the play/pause/stop/next and previous track buttons working but, what i really need now is a volume control. ive tried making a vertical scrollbar and setting to to interact "onChange Play Action Sequence" and then pointing a set property modifier at the "video" object, which would then control the volume. however, i cant get this to work. as it only chooses one volume setting, and thats it. is there any way i can make it work as any other volume slider would work?
