Flips Actor Equip Restriction v1.1

                            Flips Equip Restrictions
                                     v1.1

Hey guys and girls ;D

this is one of my first usefull (I hope so) scripts on VX-Ace.
This script helps you to restrict certain armors and weapons for actors.
I know it could be done over the Equip Types but why to set up for a
single Axe a new Equiptype because only 1 actor is using it?
Not needed anymore with this script!

Set a notetag in the equipment which should be restricted for certain actors
and it will work (:

How to use it?
Write in the notetag of a weapon or armor:

<restrict_actor: x>

or

<restrict_actor: x,x>

As an example:

if you want that the weapon with the ID 1 won't be available for the actor with
the ID 5 then do this: <restrict_actor: 5>
if actor 5, 7, 10 and 12 shouldn't be able to use the weapon then set it up like
this: <restrict_actor: 5,7,10,12>

I hope you understand what I mean (:

Version History:

v1.1
- fixed a huge bug, which would cause an error if the actor has some equipments
  equiped from beginning.

v1.0
- Got this Script to work :D
- Allows to restrict certain actors certain weapons from their equipment type
