...so, you're not asking anyone to
help you script this.
In reality, you're expecting the community to
script it for you.
How would you ever learn to script it yourself?
Doubtful that anyone is going to step forward and create this script for you. I certainly wouldn't do that...

...especially when you're not willing to even make an earnest effort yourself.
Closely examine the stock triggerzone scripts and stock door scripts, and you will easily have your solution...
and a whole new sense of self-reliance...
