[VX] Recognizing an Area in script.

Ok, so I want to make a skill that recognizes that your in an area (where you load encounters for random battles) and it will display a window that tells the player what monsters are in the area. ( Sort of a tracking skill ).  Sorry about the many questions.. but can someone tell me how to get it so that the script realizes what area your in?

To recognize in which area you are , you can use my script :
http://rmrk.net/index.php/topic,34614.0.html
But it don't tell what monsters are in this area .

Although there are a lot of scripts that could tell you what area that your character is in (dricc's AreaPlus, BulletXT's Do_Something_In_Area; MA has an area script as well), I don't think any return what monsters are in that area without a little editing. I just so happened to have my Local Area scriplets laying around, so I tossed something together for you. I'll leave the building of the tracking window to you. I've commented in several places to show where things should go.

          # 'Tracking' Window Pop-Up here.
          # Remember that this area gets updated around 60 times each second,

Thank you again, Exhydra, your a life saver, I'll play with it later.   I'm sure I'll have more questions so I'll prolly post again later when I'm messing around with it.  Thanks again!

Wouw, this seems really cool I'd love to see what comes out of this

Yes, what I'm going to be working on is a script that gets called upon using a skill, such as "Tracking" or "Knowledge: Nature",  I want it to recognize the area your in and display text saying what monsters in the area.  My game will be composed of a d20 skill system that allows you to level up skills in certain talents and up the percentage chance that they will work. 

The tracking skill will be useful for people in finding where the monsters are that they need that drop items for my crafting skills and synthesis shops.
