  Ruby Enemy Action Selection v1.01
  by Adiktuzmiko

  Date Created: 04/11/2014
  Date Last Updated: 04/11/2014
  Requires: N/A
  Difficulty: Easy

======================================================
 Overview
======================================================

 Allows you to use full RGSS3 formulas for determining
 which action an enemy will use.

======================================================
 Usage
======================================================

 Put this script into your scripts editor, probably
 below any other script that might modify Game_Enemy.
 Next thing to do is to tag your enemies. Un-tagged
 enemies will use the default method for selecting
 actions.

 <ruby_actions>
 formula
 <end_ruby_actions>

 Formula can be any valid RGSS3 formula. Accepts
 multiple lines

 example:

 Use skill 4 if HP is > 50, else use skill 10

 <ruby_actions>
   if self.hp > 50
     return 4
   else
    return 10
   end
 <end_ruby_actions>

 It is important that all situations will return a valid
 skill ID.

======================================================
 Compatibility
======================================================

 Aliases Game_Enemy's make_actions method
