    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.***

    Do you have permissions setup for it? What happens when you type /npc? Anything show in the server console?

    I will ask the developer of Citizens what they are doing to fix it...

    Delete the NPCTrader.jar (not the NPCTrader folder) and redownload it.

    This works for me. (Seems Craftbukkit loads the Plugins in downloadorder (Filedate maybe))

    Yeah for some reason my listener for iConomy stopped working, however what you can do is just /plugin enable NPCTrader once your server is started, I am going to fix this later today.

    any chance of some source code for people whos plugin didnt generate the plugins\NPCtrader folder
  20. Offline


    I really don't know why it stopped working, it's code I never changed, but I am going to look into it for next update which should be later today. But you can get the config.yml by opening the jar with any archiving program that supports it.
  21. Offline


    I've wanted to use this for a while, but it's just not possible for me. I understand that you had a lot of problems with SQLite, but I also don't use iConomy. Is there any chance you could support BOSEconomy too, or put the source on github so someone can fork it?
  22. Offline


    thanks i will be looking foward to this and will the update be compatable with CB617

    I'm using the version for 612 on 617. Works fine for me.

    I had the same issue with the config file not being generated on 612+. All you need to do is manually create the NPCTrader folder in your plugins directory and it'll generate it after a restart. Hope that helps!

    I've updated to 1.1, but still it loads before iConomy. How can I correct this?

    Wait a min.. So I have to run mySQL in the background? So far all those plugins that I've been using uses sqlite and I do not need to run anything else other than the MC server.
    I used to run maplestorey ps so it's like that? I will need to run mysql and use mysql query to edit those stuffs?

    I will have a new release out soon with fixes.

    Getting the same above errors that there's no iConomy installed even though there is. Using the command /plugin enable [whatever] doesn't do anything at all other than tell me it's an unknown console command.
