Hi, about your question. If you mean how did I made the cabin door openable well, there are objects in the game that interacts by player's actions. So to enable that ability you have to got to [ Objectives => Add Objective => Add Object => (Choose an interactive object) => Touch Object ] and when you interact with the object you'll notice that it's more like loose. That's all, thanks for asking and sorry for answering lately, good luck! ;)

Thanks Green Goo for answering, you really helped me a lot with answering, or thanks bro

The answer to your question about changing the "audio code" of your DYOM mission: Download notepad ++ then open your DYOM mission using it and there you can rename the mission audio code, ( SD/(Rename Here)/xx.mp3 ) Hope that helped. Sorry for the late answer, been busy.
