MapSwitch 2 for RPG Maker XP [Exclusive]

[PK8]

MapSwitch! 2 (RMXP)
Version: 2

Introduction
This script is pretty much designed to help developers streamline their projects with great ease. Here's how the script works and try to bear with my sloppy attempt at an explanation.

Okay so when a player enters a certain group of Map IDs, a particular switch would activate. When the player leaves one of those Map IDs, the switch that activated upon entering in the map would deactivate as well.

Again, I think it's totally useful and it helps streamline your project a little bit. Alright, here's an example:
How about marking which maps are "dungeons"? Whenever the player enters a map marked as a "dungeon", a switch would activate.

Features

• Developers can set up what group of map IDs would activate a switch.
  
• Switch deactivates whenever the player is not in a marked map ID.
  
• It might help streamline your project.
  

Screenshots
I can't screenshot this but I will say this. Try the script out, set it up, enter multiple rooms and use RMXP's debug function (press F9) to see which switches are activated.

Demo
No demo.

?                                                                              ?
?   Usage:                                                                     ?
?   Mapswitch[switch id] = [multiple map ids]                                  ?
?                                                                              ?
?   Example:                                                                   ?
?   Mapswitch[1] = [2, 3, 5]                                                   ?
?   Whenever the player is on maps 2, 3 or 5, switch 1 would activate. Whenever?
?   the player is not in any of those maps, the switch would deactivate.       ?

Author's Notes
I made v1 a year ago, mainly to give users (primarily eventers) a script which could help them out a little. Version 2 might not be much but it's a vast improvement over the first.
