[SCRIPT] How to achieve this scenario?

[serbusfish]

The scenario;

You enter a room, the sound of a plate or vase smashing is heard from another room, the centre dot 'looks' to where the sound came from, then the sound of a monster walking is heard followed by the sound of a door shutting.

How would I go about doing this? I have the actual level built ready, I just have no clue about scripting, I understand the basic idea of it but I cant just open up a text doc and type in what I want to do, whereas I have no problem opening the level editor and building a random set of aesthetically pleasing rooms (imo ).
