Need some help on a Adventure Game

Hey everybody,
I’ve made loads of simple click and search adventure games like “Grab that key and open that door”.
Easy scripting, mostly stops and GoTo’s.
Thing is, I’ve been checking out Else, If and _Root.
And I found out that stuff is way better to create these kinds of games.
If i had a game i needed to make 1 frame 10 times, because of all the items and combination of 'em.
Here’s a .fla with an easy example of how it should be.
Thing is, is there anyone who could remake that or add the scripts I mentioned earlier?
I just need a small example so I can get started by learning it on my own better.
If>you have key>Door opens, bit like that.

Thanks for the time reading this,

Santa. :sure:
