The RPG Maker Resource Kit

• v. 1.4: Made it more compatible by restoring some of the script cleanliness that was lost in the upgrade from 1.3 to 1.3b
  
• v. 1.3b: Fixed fatal error. You MUST replace v. 1.3
• v. 1.3: Added an information screen about the item. Now, you can select an item and see a breakdown of what it does. As well, added icons (major bug, please upgrade to 1.3b)
• v. 1.2: Various little design changes and aesthetic stuff. Included Ordering Tax option
• v. 1.1: Increased it's functionality by allowing the option of ordering items from the catalogue. (not released)
• v. 1.0: Made the basic screen. Viewable catalogue of all items collected

---

This script allows you to set up groups of items, and then it will give you a log of all the items in that group that the party has encountered. You can have an infinite number of groups. It also allows you to order items from a catalogue at user-specified locations. As well, it gives detailed onfo on all items you have collected.

• Easily customizable groups containing any number of items, weapons, armors, or all three
• Unlimited number of groups
• Displays all the items in that group that have been encountered so far, as well as the price in a store
• Has a ratio in the corner between the items encountered and total items in a group
• Can set up an event which allows you to order items from a specified catalogue
• Can attach an ordering tax on ordering from the catalogue of whatever you desire
• Shows all the stats and descriptions of each and every item through a window accessible when you are not ordering.

# Catalogue Script
# Version: 1.4
# Author: modern algebra
# Date: July 10, 2007
#------------------------------------------------------------------------------
# Description: Allows you to have a log of all items collected and not yet
# collected.
#------------------------------------------------------------------------------
# Instructions: This script allows you to set up groups of items (items, weapons,
#               and/or armors. All types can be contained within a single group)
#               and allows you to view which of the items in that group have
#               been in your party's possession. By default, there are three
#               groups: items, weapons, armors. But you can change these and add
#               more very easily. To use, call this in a script:
#
#                    $scene = Scene_Catalogue.new (X)
#
#               where X is the group number. I'd suggest this script to be used
#               as items which call common events which have that $scene thing
#               in them. By default, it exits to the item menu. Instructions on
#               how to configure the group are at line 31
#------------------------------------------------------------------------------             
# You can also use this as a method of ordering, like from a real catalogue.
# Basically, it brings up your item log, and you can choose any of the items to
# buy. This can be useful for an Animal Crossing Game for example, but I think
# it can be useful for many types of games. In order to use this feature, use
# this call script:
#
#   $scene = Scene_Catalogue.new (X,Y)
#
# where X is the group number and Y is the ordering tax coefficient. I.e., Y is
# a number, and whatever you make that number it will multiply the price by it.
# For example, if Y = 1.15, then there will be 15% ordering tax. I.e. if an item
# costs 50 Gold in a store, then it would cost 58 Gold to order it from the
# catalogue.

    # CONFIGURABLE AREA
    #---------------------------------------------------------------------------
    # To make a group, make an array, and place each item you wish to have in
    # that group inside the array. Example:
    #
    # @catalogue.push (["Fish",[$data_items[1], $data_items[3], $data_items[32]]])
    # @catalogue.push (["Gold Items",[$data_armors[5], $data_weapons[3]]])
    #
    # That would make two groups. The first group would be called "Fish" and
    # have item 1, item 3, and item 32 in it, and the second group would be
    # called "Gold Items" and include armor 5 and weapon 3 in it.
    # By default, there are three categories, items, weapons and armors.
    #---------------------------------------------------------------------------
    # The basic set up:
    # @catalogue.push (["name", [<array of items included in the group>]])
    #
    # You can set up as many groups as you like.
    #
    # If you know how, you can also put them on the same line, like this:
    # @catalogue = [["Items",$data_items],["Weapons",$data_weapons],["Armors", $data_armors]]
    # but to keep it simple, follow the instructions. In default, items group is
    # 0, weapons group is 1, armors group is 2, and if you add another group
    # underneath, it would be 3, and so on. So, $scene = Scene_Catalogue.new (0)
    # would bring up the items log, etc...

• modern algebra

• zzzdude, for the request

I am willing to rectify any incompatibility issues and fix any bugs. Unless it is a very interesting request, I will not add major features to this upon one user's request, though if many people want it I will do it. I will provide support for this script here at rmrk and at rmrevolution.rmrk.net. If this script is posted elsewhere (other then rmrk, rmrevolution, chaosproject, and RPG RPG Revolution), I am not aware of it and as such, am not able to provide support.  On that note, please don't steal my script.


It will not work with any script which overwrites Window_Gold or Window_ShopNumber
It will not initialize for old savefiles.
This ought to be compatible with SDK. No guarantees once they release the version that separates Window_Gold into nine methods ^_^ (just kidding)

---

See Attached

This sounds great. This would be useful for an Animal Crossing game.

Thanks  ;D

Anyway, I am now posting v. 1.2. I decided to make it so that at user-specified areas you can order items from the catalogue. i.e. buy any item that you've previously owned in whichever group you specify. You can also set a tax for ordering it  :police:

EDIT:

Did it up under the guidelines of the new template. I think it looks good  :lol:

This looks really sweet :D +rep to you matey :P

*

Updated to Version 1.3. Now you can view detailed information on any item. As well, icons are shown now, and I fixed a major source of incompatibility between other item scripts. It should work with most any script now.

wow, thanks!
Sorry for leaving, my laptop broke, had to send it in while I was visiting california, long stupid ordeal with compaq, internet got disconnected, loads of other crap.

I am ganna use this script, EXTREMELY useful.

how do I give rep    :P

i downloaded the demo but there's a problem with both the demo and when i fixed it up in my game, i can't equip any weapons or armours or accesories, and the ones that i have equipped, one i un-equip them, they disappear

Odd, you're right, I think it must have happened when I modified soe of the script for v. 1.3

I'll fix it soon and post a new script/demo


Okay, the new script that is up should work. It is incompatible with other scripts which modify gain_item, gain_weapon, and gain_armor methods of Game_Party. I will fix that soon. I think the problem occured because I improperly aliased those methods. So, to fix it quick, I just overwrote them, but I will post a better version when I have time.

Hmmm...
Say I want a group with items # 37-47, 1-5, etc.
Would I have to go and make [$data_items[37] [$data_items[38]... all the way through 47? or is there a shortcut...

Shortcut:

$data_items[X,Y]

where X is the id of the first item in the database, and Y is the amount of items after that you want to include. Examples:

$data_items[37,11] returns items 37-47
$data_items[1,5] returns items 1-5

Also, make sure you have v. 1.3b

yea, I do.
Know Y, does that count the first number as well?
So it is 37 AND  all the numbers after it?

yes, it counts 37

i want to make a log that included selected ID of weapons and also some Armor IDs (accessories), reason for this is that some of the accessories whihc you can equip are added parts for some weapons, how would i go out this, would i have to combine [$data_weapons[IDs]] and [$data_armors[IDs]] in the same pair ()

Like this:

[$data_armors[ID], $data_weapons[ID], etc...]

if you plan to make another version of this script, i got some suggestions

1. have the script make it so that it shows a complete list of weapons, items & armors but as black icons and can not be read and when you do get that item, weapon or armor, it shows up so you can see what weapons you have got and what ones your missing, good for gamers who like colecting every item in the game

2. a catalogue that lists monsters and their stats
        EDIT: the ones you encounter, thanks zzzdude, i forgot to add that

you don't have to do any of these, their just ideas

How about monsters you encounter, because then a boss battle would be to predictable.

Just modified the code to improve the compatibility. My quick fix for v. 1.3b was to overwrite some methods, so if you want to replace 1.3b with 1.4, you can. You don't need to though, as the only thing I changed was compatibility and I made a small edit to the way the Equippable Classes are drawn and I removed the name/price labels. However, if you are not experiencing a compatibility issue, then it isn't necessary to upgrade. If you do upgrade, remember to retain your groups and copy them into the new script.

And I'll make a special version for you which draws all items. but disables the ones you haven't encountered.

As for the bestiary, maybe, we'll see.

EDIT:

Here is your version, Memor-X


#===============================================================================
# Catalogue Script
# Version: 1.4 Memor-X Edition
# Author: modern algebra
# Date: July 10, 2007
#------------------------------------------------------------------------------
# Description: Allows you to have a log of all items collected and not yet
# collected.
#------------------------------------------------------------------------------
# Instructions: This script allows you to set up groups of items (items, weapons,
#               and/or armors. All types can be contained within a single group)
#               and allows you to view which of the items in that group have
#               been in your party's possession. By default, there are three
#               groups: items, weapons, armors. But you can change these and add
#               more very easily. To use, call this in a script:
#
#                    $scene = Scene_Catalogue.new (X)
#
#               where X is the group number. I'd suggest this script to be used
#               as items which call common events which have that $scene thing
#               in them. By default, it exits to the item menu. Instructions on
#               how to configure the group are at line 31
#------------------------------------------------------------------------------             
# You can also use this as a method of ordering, like from a real catalogue.
# Basically, it brings up your item log, and you can choose any of the items to
# buy. This can be useful for an Animal Crossing Game for example, but I think
# it can be useful for many types of games. In order to use this feature, use
# this call script:
#
#   $scene = Scene_Catalogue.new (X,Y)
#
# where X is the group number and Y is the ordering tax coefficient. I.e., Y is
# a number, and whatever you make that number it will multiply the price by it.
# For example, if Y = 1.15, then there will be 15% ordering tax. I.e. if an item
# costs 50 Gold in a store, then it would cost 58 Gold to order it from the
# catalogue.

    #===========================================================================
    # CONFIGURABLE AREA
    #---------------------------------------------------------------------------
    # To make a group, make an array, and place each item you wish to have in
    # that group inside the array. Example:
    #
    # $catalogue.push (["Fish",[$data_items[1], $data_items[3], $data_items[32]]])
    # $catalogue.push (["Gold Items",[$data_armors[5], $data_weapons[3]]])
    #
    # That would make two groups. The first group would be called "Fish" and
    # have item 1, item 3, and item 32 in it, and the second group would be
    # called "Gold Items" and include armor 5 and weapon 3 in it.
    # By default, there are three categories, items, weapons and armors.
    #---------------------------------------------------------------------------
    # The basic set up:
    # $catalogue.push (["name", [<array of items included in the group>]])
    #
    # You can set up as many groups as you like.
    #
    # If you know how, you can also put them on the same line, like this:
    # $catalogue = [["Items",$data_items],["Weapons",$data_weapons],["Armors", $data_armors]]
    # but to keep it simple, follow the instructions. In default, items group is
    # 0, weapons group is 1, armors group is 2, and if you add another group
    # underneath, it would be 3, and so on. So, $scene = Scene_Catalogue.new (0)

I haven't really tested it, but it ought to work. And:

QuoteIf you do upgrade, remember to retain your groups and copy them into the new script.

thanks modern algebra, you'll be remembered for this

Alright, I've been working on a version 2.0 for this, and the purpose of my update is to allow easy integration for any type of catalogue information you might desire. What this means is that you can make groups which hold monsters, or skills, or whatever other type of data you might want to make catalogues for and use the catalogue interface to get to that information (Naturally, to make your own groups you would need to be a scripter, but I am willing to make groups for you if you cannot). Considering this, I wanted to know what you guys felt of this design for the bestiary data:

This is of a large battler, as I wanted to test the size translation

I will probably make some sort of analyze skill effect to go along with it, and only display information if the creature has been analyzed. However, what do you guys think of the info I show? Should I show all the specific stats? Should I show EXP and Gold somewhere? Should I shrink large battlers so that they do not take up so much space? Should I do something with the icons to make it more clear what elements the creature is strong or weak against? Should I get rid of the letters and just have the opacity show that?

I appreciate any comments. Also, it looks like the window is not centred, but it is, my windowblinds just cuts stuff.

Instead of having the monsters battler in the backround, I would suggest making a new window, with a smaller version of the monsters battler inside. Having the battler in the backround, makes it harder for some people to read the white text if the text cross the battler.(Or black, wich depends on wich colour you have on the text :)), but that's just what I think.

Other from that, it sounds like a nice edition to the script.

Well, most monsters wouldn't have so large a battler. I don't like the idea of a new window, assuming that by that you mean a window that you call if you want to see the battler (I am assuming that simply because having another window visible at the same time doesn't rectify the problem). However, I could shrink large battlers when they expand over the text. I'll post what that looks like in a bit. Alternately, I could make the battler semi-transparent, more so then it already is.

The shrunken battler looks like this:

And the low opacity like this:

Naturally, I wouldn't do either unless the battler is wide and expands over the text

Very nice addition to the script, modern algebra!
But I think a better design is a split-screen.

One contains the monsters' stats, while the other the pic and description. :)

A picture of what you mean? I don't really see how it would accomodate large battlers to split screen it. Maybe I just don't get what you mean  :-\
Show me a picture.

Also, what do you guys think of this:

Should I just leave icons out of the bestiary? They can look pretty crappy resized like that. If you think I should, which looks better? THe one aabove or:
