Conditional Skills and Equipment VX
Version: 2.6.1

Introduction

I was inspired by a request to make this script. It allows you to set special use conditions to any skills or equipement you want. It's a very simple script and is currently under development, but I wanted to post it anyway.

Read Instructions Before Using

Features

Allows you to make skills and equipment that require special conditions to be used.

These include:

You can set the script to remove equipment when they don't meet their requirements anymore

eg. A Begginers Below Level 5 Sword will be removed when you reach level 5

The script can also hide any skills you want when they can't be used.

Screenshots

Can't really take a screenshot....

#==============================================================================

#

#  - INTRODUCTION -

#

# This script can be used to set special use conditions to skills and equipment

# There are a number of different ones you can check:

#

#------------------------------------------------------------------------------

#

#  - FEATURES - 

#

#  There are a number of different Conditional features that can be used

#  These include:

#

#  STATE  - Whether certain states are inflicted

#  WEAPON - Whether certain weapons are equipped

#  ARMOUR - Whether certain armours are equipped

#  ITEM   - Whether certain items are in your inventory (which can be used up)

#  HP     - Whether HP is MORE or LESS than a percent of the MAXHP

#  GOLD   - Whether the party has a certain amount of gold (which can be used up)

#  LEVEL  - Whether the LEVEL is MORE or LESS than a certain point

#  CLASS  - Whether the actor is a certain class

#  PARTYMEMBER - Whether a certain actor is in your party (and alive)

#  PARTYNUMBER - Whether a certain amount of actors are in your party (and alive)

#  FREEHAND    - Whether the actor has 1 or 2 free hands

#  ATK  -  Whether the actor has a certain amount of ATK

#  DEF  -  Whether the actor has a certain amount of DEF

#  SPI  -  Whether the actor has a certain amount of SPI

#  AGI  -  Whether the actor has a certain amount of AGI

#

#  NOSHOW - Add this to make a skill not appear when it can't be used

#

#  More than one can be used on any skill or equipement

#  However only some can be used for skills and only some for equipement

#

#------------------------------------------------------------------------------

#

#  - USAGE -

#

#  First make a skill/equipment in the Database and in it's note box place this:

#

#        <skill>                  <equip>

#         .....         or         .....

#        <skill>                  <equip>

#

#  You must place any necessary Coding or tags in there

#  Anything you place in there must be on a separate line

#

#  Condition tags must be followed by a number, multiple numbers can be entered

#  these must be separated by a comma ','

#  Some conditions can use the '&' feature

#

#  See EXAMPLES if you are unsure  

#

#------------------------------------------------------------------------------

#

#  - SKILLS -

#

#   The special conditions that can be set to skills are as follows:

#

#           STATE  WEAPON  ARMOUR  HPLESS  HPMORE

#           FREEHAND  ITEM  ITEMUSE  GOLD  GOLDUSE

#                LEVELLESS  LEVELMORE  CLASS

#                 PARTYNUMBER  PARTYMEMBER

#

#------------------------------------------------------------------------------

#

# - EQUIPMENT - 

#

#   The special conditions that can be set to equipment are as follows:

#

#           LEVELLESS  LEVELMORE  WEAPON  ARMOUR

#                    ATK  DEF  SPI  AGI

#

#------------------------------------------------------------------------------

#

#  - EXAMPLES -

#

#   Here is a list of examples to show you how to use each condition:

#

#   STATE12    -  State 12 must be inflicted to use the skill

#   WEAPON1    -  Weapon 1 must be equipped to use the skill

#   ARMOUR2,9  -  Both armours 2 and 9 must be equipped to use the skill

#   FREEHAND2  -  Both of the actors hands must be free to use the skill

#   HPLESS25   -  Health must be below 25% to use the skill

#   HPMORE50   -  Health must be above 50% to use the skill

#   ITEM1,2    -  Must have items 1, 2 and 3 to use the skill

#   ITEMUSE1,2 -  Must have and will use 1 of items 1 and 2 to use the skill

#   ITEM1&3,2  -  Must have 3 of item 1 and 1 of item 2 to use the skill

#   ITEMUSE1&3 -  Must have and will use 3 of item 1 to use the skill

#   GOLD1000   -  Must have 1000 Gold to use the skill

#   GOLDUSE100 -  Must have and will use 100 Gold to use the skill

#   CLASS1,2   -  Must be Class 1 or 2 (RTP : Paladin, Warrior) to use the skill

#   LEVELLESS5 -  Must be under Level 5 to use the skill

#   LEVELMORE9 -  Must be over level 9 to use the skill

#   PARTYMEMBER4 -  Must have Actor 4 (RTP : Ylva) to use the skill

#   PARTYNUMBER3 -  Must have 3 or more actors in the party to use the skill

#   ATK100  -  Must have ATK greater than or equal to 100

#   DEF100  -  Must have DEF greater than or equal to 100

#   SPI100  -  Must have SPI greater than or equal to 100

#   AGI100  -  Must have AGI greater than or equal to 100

 # Remove Equipment when conditions don't apply anymore?

 REMOVE_EQUIP  = true

 # Show a message saying that the equipment has been removed?

 SHOW_MESSAGE  = true

 # Speed at which the message will disappear

 MESSAGE_SPEED = 2     # 1 = Slow     2 = Medium     3+ = Very Fast

 # Amount of frames the message will stay for

 MESSAGE_STAY = 20     # 20 is average - You want it lower if the speed is slow

 # Use an Icon in the message?

 USE_ICON      = true

 # Message that tells you what has been removed

 EQUIP_REMOVE  = "%s unequipped"

 # Message explain's why

 EQUIP_MESSAGE = "%s can't use it anymore"

Compatibility

Compatible with most things I hope. However, this script is under development, so bugs may occur. The script also changes 'Window_Skill's 'refresh' command and 'Scene_Equip's 'update_item_selection' command. However the small pieces of coding can easily be added where you need it.
