That nasty SP bar

[Mel]

Hey,

I'm using this HP/SP bar script for enemies and have one problem.
When refilling the SP with a potion or SP heal state, the bar doesn't update correctly.

The HP bar works perfectly fine but the SP bar not. It only updates after using another skill.

Does anyone have an idea what to do?
I think the easiest way is to code the SP bar exactly like the HP bar but I'm too bad to accomplish that..

Here is the script. It's only copy and paste.

Code:

#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
# Enemy/Actor HP & SP Bars +
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
# By: El Conducter +
# Updated: January/08/08 +
# Version: 4.0 +
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
#
# Update History:
# Version 1.0 - Displays enemy & actor HP & SP bars in battle.
#
# Version 2.0 - Made the enemy HP bars more centered aligned with the
# enemy. Actor bars now also show in menu screen.
#
# Version 3.0 - Module added to change bar lengths easier.
#
# Version 4.0 - System Rebuilt, new look for bars, new scrolling ability,
# more customizable features, bars on menu screen is lost,
# SDK compatible
#----------------------------------------------------------------------------

#----------------------------------------------------------------------------
# What it Does:
# See enemy and actor HP/SP bars during battle.
#
#----------------------------------------------------------------------------

#----------------------------------------------------------------------------
# How it Works:
#
# This version of the script works similar to the previous versions,
# however it runs a lot differently. Rather than the invisible window
# to display the bars as in previous versions, sub-sprites are used
# instead. The same effects can be achieved this way with more efficeincy
# and less code. New fetures can be taken advantage of through this new
# system like the ability for visual filling and depletion of bars.
# Though not built directly for the SDK, this script will work with or
# without it.
#
# Lengths and settings for the bars are stored in module Bar_Config.
#
# New and altered scripts are:
#
# - module Bar_Length
# - Sprite_HP_Bar
# - Sprite_SP_Bar
# - Sprite_Battler
# - Game_Battler
# - Scene_Battle
#
#----------------------------------------------------------------------------

#----------------------------------------------------------------------------
# How to Use This Script:
# Just copy it and paste it above Main. If using the SDK, paste below SDK
# and above Main.
#
# To change the bar lengths and other settings go to module Bar_Config
# and change the values there.
#----------------------------------------------------------------------------

#----------------------------------------------------------------------------
# Comments:
# I hope my script is easy for you to use and modify. Study this script
# to learn the ways of RGSS and join the ranks of those known as 'Scripters'.
