    NPC Trader - The Full featured localized shop system

    Version 1.1.4 (Testing Version!)

    The first localized full featured shop system for Bukkit/iConomy, in NPC Form!

    What's better for a localized shop system then your very own NPC Clerk / Teller / Worker / Slave / Whatever word you want to call your NPC!

    • Localized system
    • Fully player controlled (No admin intervention needed)
    • Full Item and Metadata support (Colored wools, etc)
    • Item name or ID recognition
    • Partial name recognition (If online)
    • Complete internal permissions system for managers of the NPC
    • iConomy Based
    • MySQL data storage
    • Item stocking system
    • In-Game help for everything
    • Supports Permissions and GroupManager (Using FakePermissions) Plugins!
    Installation / Setup

    1. Put NPCTrader.jar in your plugins folder
    2. Put mysql-connector-java-bin.jar in your main minecraft folder
    3. Restart your server (Auto-generates config.yml in plugins/NPCTrader/)
    4. Edit the config.yml for MySQL and other config settings.
    5. Restart once more
    6. Enjoy!
    If for some reason the folder / config does not auto-generate, then you can open the .jar file with 7zip or winzip or other archiving utility that supports jars and extract the config.yml from the jar.

    NOTE: If you do not have or do not know if you have MySQL setup then you either have to setup MySQL or not use this plugin for now. Please do not post questions asking how to install MySQL as that is outside of the scope of this post. You can follow this tutorial (Thanks @Germata!) for detailed windows installation and setup, but I cannot provide support for installing and setting up MySQL, only support for my plugin specifically.


    Permissions will only be used if it is installed. The following is the permissions list:

    npc.admin      - Give to admins for full access to all NPCs
    npc.admin.list - Access to /npc list npcs
    npc.user.*     - General user commands, you can specify by replacing * with command name, I.E. buy
    npc.manager.*  - NPC Manager commands
    npc.owner.*    - NPC Owner commands
    npc.create     - Ability to create an NPC 
    If permissions is used you may also specify limits on how many NPCs a specific player or group may have ownership flag on, please see config file for more information.


    Once the plugin is installed and running, you can see the in-game help by typing /npc in your chat window. To interact with an NPC just right click on it first.

    Here is a simple tutorial for setting up an NPC named Bob that sell's bread, cooked fish, and cooked pork, and buys wheat, raw fish, and raw pork.

    1. Stand exactly where you want your NPC, including head position and body rotation.
    2. Type: /npc create Bob 6 10 This will create the NPC with 6 Item Slots, each holding 10 units.
    3. Right click on the newly created NPC
    4. Type: /npc setup 1 bread 1 2 0 true false This will setup Slot 1 with Bread, selling lots of 1 at 2 Coins, buying them from players at 0, True for NPC Selling it, False for buying from players.
    5. Repeat step 4 for Cooked fish and Pork
    6. Type: /npc setup 4 wheat 64 0 10 false true This will setup Slot 4 with Wheat, buying lots of 64 at 10 Coins. This one is set False to selling it to players, but true to buy from players.
    7. Type: /npc stock 1 20 This will stock the NPC with 20 breads on slot 1 (Assuming you have enough bread).
    8. Repeat step 7 for raw fish and pork.
    You know have a fully setup and functioning NPC.

    Known Issues / Bugs

    • Config folder does not get generated on Linux - Works on Windows
    • Cookies and beds, and pretty much any other 1.4/1.5 items.
    • Spams console when you stand close to an NPC
    • Gives error when an NPC is spawned (Can be ignored)
    • Head / Rotation is not being properly set on spawn / move. (Fixed in 1.14)
    • Does not work with actual permissions (works with GroupManager)
    • Rename command is broken
    Things Todo

    • Re-write item handling
    • Support for both GroupManager and Permissions
    • iConomy 5 Support
    • Add armor capacity
    • Tie into WorldGuard for checking for build rights (Will be optional)

    If you installed MySQL for Windows just to run this plugin then check out this link to see how to create the initial minecraft database you will need.

    *** NOTE: SQLite IS NEVER GONNA HAPPEN! If you want to see an alternative, fork the src, make it work as an option, and I will include it in.***

    The root of the problem is that we have a bunch of different plugins all doing the same basic thing using different config file formats.

    There are 3 solutions in my mind:
    1) All these permission plugin authors sit down and set a standard that they all work on so we have one well developed plugin​
    2) The Bukkit team picks an official permission plugin​

    And the best one, which is the best long term solution:
    3) The Bukkit team gets their own permission solution implemented​

    Is it possible to edit the skins for the NPC's?
  5. Offline


    when i try to create an npc it says
    "an internal error occurred while trying to perform this task"
  6. Offline


    I believe it goes off your char.png file, so if you change that, the NPC skin will be that skin when you create the NPC. Atleast that's how I think it works!

    Yes, the most of us have this problem. Hope MatCat will fix this with the next update.

    Hey, is there a way to change what the npcs say when you approach them? Would be nice to have some of them say something other than "Can I interest you in anything?" [​IMG].

    I know what's causing the error

    Caused by: java.lang.NoSuchMethodException: com.MatCat.NPCTrader.NPCTrader.<init>()
    .. I had the same problem when I tried recompiling SearchIDs. The error was being caused by plugin.getDescription() failing for no apparent reason. The solution I found was to hard-code the plugin name and version (SearchIDs, 1.21-gigawatts) to get it to not fail on load.

    This has been addressed as Bug #512 - but they say it's not a bug, just a compatibility error.

    If I had the source I'd try hacking at it. :)

    Hope this helps!

    What the hell is MySQL??? I Dunno how to install this mod please describe better
  30. Offline


    MySQL is not a mod nor is it anything thats been developed by any of the developers for bukkit. MySQL is a peice of software that is usually used on webservers and games servers as a data storage application. It can store billions of lines of data easily with the only limitation being the amount of hard drive space availiable it runs completely independant of Bukkit.

    If you are looking for a good peices of MySQL server software lookup Wamp server. very easy to setup and very intuitive.

    And it's used on more than webservers and game servers - It's a database. It's used really anywhere data storage is needed.
