[XP]Chrono Cross Key Items Script Help [SOLVED]

[Poptart]

Hello, I'm just requesting a little help with the script "Chrono Cross Key Items". Everything seems to work nicely with the exception of, if I make two or more conditional branches, only the first one will work. But, I'd like to have an event react differently to different items selected...



Link to script:
http://forum.chaos-project.com/index.php/topic,12727.0.html

Any help would be appreciated..

The reason is this:

class Interpreter
  def used_item(id)
    flag = id == $game_temp.key_item
    $game_temp.key_item = 0 #<============= This
    return flag
  end
end

The item you select is stored in $game_temp.key_item. Then, when you call used_item the first time, it will clear out the $game_temp.key_item with a zero. Thus, using used_item a second time will compare your ID with a zero...so it will always fail.

You can remove this offending line from the script, but I would suggest that, in all your events using the script call used_item, to put another script call

$game_temp.key_item = 0

somewhere near the end of it.

Thank you so much!

Okay, it didn't take very long to fix it. I didn't really test it much but I think it should work technically.

Code: ruby

# Chrono Cross Key Items
# Version 1.1
# Author gameus
#-------------------------------------------------------------------------------
# Intro:
# Ever play Chrono Cross? You can bring up a window that displays a list of 
# your Key Items and you can use them on NPCs and events to have a 
# certain action take place.
#
# Features:
# -Display All Items or Marked Items
# -Won't conflict while events are running
# -Use items on NPCs and have something happen
#
# Instructions:
# This script is pretty much plug-n-play. But you have to decide if you want
# to display All Items or just Key Items. If you just want Key Items, scroll
# down and set "CCKEY_SHOW_ALL_ITEMS" to false. Then be sure to create a 
# unique element which will be used as your Key Item Element. Mark any item
# with this element that you want made as a key item. Then set 
# "CCKEY_ITEM_ELEMENT" to that element's id.
#
# Using this with Events:
# All it requires is a simple Conditional Branch Script Call. 
#   used_item(item_id)
#   -item_id = The id of the item you'd like the event to react to.
# It's a bit hard to explain, but that's why there's a demo.
#
# Compatibility:
# -Not tested with SDK
# -Shouldn't conflict with anything
#
# Version History:
# 1.0
# -Initial Release
#
# 1.1
# -Allowed multiple item calls in one event page
#
# Credits:
# gameus ~ For creating the script
# SquareSoft ~ For inspiring the script

Works great. I know the thread was about a month old, but saw it and wanted to fix it. Will update main post now.
