Serial Killer, I
STRONGLY recommend that you read the command reference (preferably the online version, and also the unofficial version too) from front to back, like a book. Twice.
Don't stop to understand every command in detail, but get a good feel for what is there. From the questions you have been posting you are obviously making a fairly script-intensive mission, which is great, but you're trying to do it without knowing your tools - the scripting commands. In light of your question here, you may find the Cs particularly interesting.
Having studied the comref, spend a good few hours in the rest of the Editors Depot. For example, something I do every now and again is read through the list of scripts that are available. Far better to use existing scripts in your mission than constantly writing your own or worse still reinventing the wheel.
The forum is for when you get stuck: it is not the first port of call.
If you are faced with a problem and have no idea how to solve it, the first thing to do is go back to the comref and see what you can find.
