怎样让遇敌时自定义优势条

KB.Driver

所谓优势条，指的是：

像这样的东西 遇敌就会弹出然后滑动 在不同位置停下会有不同效果
但是脚本中设定是优势一定在最左，劣势一定在最右，变化的只是长度。
我希望能够自定义不同敌群的遇敌条，有办法实现吗？要怎么实现呢？

# 2012.02.01 - Started Script and Finished.
#
#==============================================================================
# ▼ Introduction
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# Whenever a random encounter initiates, a gauge will appear on screen. And
# depending on the timing regarding a player's button input, the battle will
# start off as a pre-emptive attack for the party, a normal battle, or even a
# surprise attack from the enemy.
#
#==============================================================================
# ▼ Instructions
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# To install this script, open up your script editor and copy/paste this script
# to an open slot below ▼ Materials/素材 but above ▼ Main. Remember to save.
#
# Create or download an image with the filename "BattleAdvantage" within the
# Graphics\Pictures\ folder of your project.
#
#==============================================================================
# ▼ Compatibility
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# This script is made strictly for RPG Maker VX Ace. It is highly unlikely that
# it will run with RPG Maker VX without adjusting.
