custom story idea : the darkness

[pandasFTW]

You wake up in a strange room, which you, at first look, dont recognize, but you are not sure though, because you are barely able to see anything through the pitch-black darkness... outside the window, you hear horrible noises, and it sounds like they are coming closer.


this is the story for my new custom story! this is my first custom story though. i have tried to make custom stories before, but had to give up, because i am really REALLY bad at scripting... so i,d really like some help from you guys on how i do scripting, i,d really like to know the basics, y'know, making locked doors which open when using a key, and making monsters spawn when i pick up that key or enter an area. how to make them start walking around in search of me. and then, after ( hopefully ) having failed to find me, de-spawn again...
i really hope to get some help from you guys!
thanks :-)
