    ItemCraft is a Bukkit mod that allows adding new item and block types, crafting and furnace recipes, and custom tree generators and more. Using a Modloader and SettingsGUI interface it allows subplugins known as ICPlugins to be loaded to support client mods. ICPlugins can be created by translating a client mod using the ICTranslator ICplugin. Using a ModloaderMP interface (ported by krnlyng/liar) it allows porting multiplayer mods to bukkit.

    • Add more Block types
    • Add more Item types
    • Add more Entity types
    • Add more TileEntity types
    • Add more Crafting recipes
    • Add more Smelting recipes
    • Add more Tree generators
    • Ported ModLoader interface
    • Ported ModLoaderMP interface
    • Fake GUIAPI Settings interface
    • Startup file for configuring plugins and making simple blocks and items

    Installation & Usage:
    • Back up your world(s). Just in case.
    • ItemCraft.jar goes in same folder as craftbukkit
    • IC plugins go into ItemCraft/ICPlugins folder under craftbukkit. (folder is autocreated the first time)
    • uncomment (remove #) in front of all plugins you want to use in plugins.ics (autocreated in ItemCraft/ICScript)
    • Make sure you have the recommended version of craftbukkit in the title - since this is a mod of that version in particular.
    • Delete/rename the META-INF folder inside craftbukkit-0.0.1-SNAPSHOT.jar (Use some decent zip program (e.g. 7zip) that can do it.)
    • All players on the server needs to have the client mods installed
    • If you use the 16 bit entity id packet mod (in case you use new entites (only ICMCreatures need it)), All players need (flan's unofficial) ModLoaderMP client mod
    • All players also need the 16 bit entity id packet mod (overwrites a ModLoaderMP's class so make sure ModLoaderMP is installed first) in case you use new entites (only ICMCreatures need it) If decide not to use the packet mod, you can turn it off putting this in your startup file: false setEntityIDPacketMod
    • Sometimes you get block/item ID conflicts, between plugins. You then need to set the conflicting ids in the startup script using setID command: example. They have to be set before the plugin that uses them is loaded. Note also that there is typically a props file on the clientside you have to edit the ids on to be the same as well.
    • To start:
      • Windows:
        java -Xmx1024M -Xms1024M -cp ItemCraft.jar;craftbukkit-0.0.1-SNAPSHOT.jar org.bukkit.craftbukkit.Main
      • Others:
        java -Xmx1024M -Xms1024M -cp ItemCraft.jar:craftbukkit-0.0.1-SNAPSHOT.jar org.bukkit.craftbukkit.Main

      Reporting errors:
      • Read known issues - don't report those.
      • State the version of CB, ItemCraft and ICPlugin(s) you have problems with
      • If your client crashes, start the client from command line so that you get the error report.
      • Make sure the mod(s) works in SSP First before you report any errors here.
      • You are more likely to get a response if you describe the problem in more detail and do some testing yourself first of under what circumstances it occurs
      • Do not ask for uploads of minecraft.jar.
      • Do not pm me.
      • If you have problems installing, you are likely doing something wrong. Make sure you've followed the instructions exactly, read the FAQ and Wiki. If that doesn't work you can always ask in the thread, while I will likely not reply, there are others who can help you with your problem. But at least try to get it working yourself first.

      That said, I want to thank all who have helped users with their problems. In particular special thanks to icephantom and Asymetrikon for their big efforts in this. Also a special thanks to xeronut for being generally helpful.

    I'm afraid to say I'm in quite the bind. Today I attempted to add nadonalt's trees to my server by using your example startup and properties configuration. Everything seems to work fine at first untill I made the mistake of using /item to give myself one of the custom blocks. From that point on my client just froze and now I am unable to log into my server using my username because of whats in my inventory.

    I checked modloader.txt for my client and there doesnt seem to be any meaningful error outputs, same thing for my server.log

    config usedefaults
    id blockTopiary 153
    id blockPalmLeaves 154
    id blockPalmTrunk 155
    id blockPalmSapling 156
    id blockBanana 157
    id itemBanana 7422
    id itemBananaGreen 7423
    id blockBananaCake 158
    id itemBananaCake 7424

    plugin ICNTrees.jar
    plugin KSlopes.jar
    plugin ICFancyPack.jar

    I don't know what to do :(
    Please help!

    Hey ho,
    is planned to implement "Ceiling Stairs" and Hedgges & Shears" from Kaevator?
    Best Regards

    Its probably Essentials /give. Before this I always deleted my player file when this happened, but now that I've changed the dummy id to 255, you can actually put in a block with that id and then throw that item in lava to get rid of it.

    Earlier there was quite popular demand of Mo's creatures, so I translated it and am at the moment expanding the fake GUIAPI to support more settings that it uses. I have no idea if this will work though, its the first time I'm dealing with mobs.

    ok, it works, more or less (itemcraft 0.6.1 with KSlopes 1.2 on cb-766)
    works on Linux with RemoteRestartToolkit
    works on Windows only without the rkit
    crafting recipes works fine
    BUT: when i create an item via TooManyItems or /item i get a dummy and mc crashes and get a bad-login until i restart the server, clean the inventory and restart again to prevent another crash or simply delete the userfile in the world-dir
    sry that i cant give you an error-log but mc closes too fast to see it and the server-log is clean, no error
    when i use TooManyItems in soloplayer it works fine

    Confirmed DefaultCommands v3.3.0 is causing the crash. Even after emptying the inventory and loading up the server with DefaultCommands enabled and then joining with an empty inventory results in a crash. Disable DefaultCommands and everything works perfectly.

    I'm not sure I quite understand the whole dummy id thing. Are there any plugins that use the /item /give command which are safe to use with these custom blocks? If not then thats fine, I only used /item in the first place to see if the blocks are working. I think nadonalt's trees only has two recipies, which brings me to my next question.

    Are the custom trees only spawnable on chunk generation or do some saplings have the off chance of turning into another tree? I understand I need to first add the right lines to my startup.txt if I want the trees to spawn by themselfs. However I'm wondering if I could just add custom recipes to my startup.txt in order to obtain the custom saplings, which I could then plant and watch flourish.

    Sorry for all of the questions, I'm just a little confused as to how this all works.

    Support for MO' Creatures would be GREAT! I don't have any NPC plugins so Having a little more life on my server would be awesome. :)

    I have tried a lot plugins wich allow a give command... the only one that works for me and does not crash the client was SimpleGive - its not perfect but it works.

    not working as i experienced:

    - PlgEssentials
    - Essentials
    - AdminCommand
    - xGive
    - DefaulCommand

    and surely the command from the server-console works too... op yourself with op [youringamename] in the console then /give [name][id][amount] works. but you cannot use this with toomanyitems...

    The default /give works. Problem is other plugins override it.
    I'm not sure, it hasn't been tested yet.
    Yes you can add custom crafting recipes to craft saplings.

    Mo's creatures works. There was an issue with entity type ids being cast down to byte causing client to crash with negative entity ids, and since Modloader uses ids of 3000+, and I'm thinking 256 ids is going to be way too little if you want to run various mods, I decided to mod the packets to handle 16 bit ids on both server and client side and it turned out to be a success. So in order to use Mo's creatures the users will also have to download my 16 bit entity id packet client mod. I was going to post the plugin yesterday but my internet connection was gone. So I started or rather continued to work on the mimic block feature that I intended to have in 0.7. Since its almost finished now, I'm going to finish it and then upload both.

    I'm also anticipating some problems with using several mods that register new entities, because of the way Modloader works. Hopefully they can be resolved by simply loading the plugins in the right order. Which should work unless Modloader does some unpredictable stuff delegating unique ids.

    KSlopes reactions with plugins/cmd's:
    WorldEdit: does not copy Slopes, but copies Slopes in Chests
    SuperPickaxe: returns the base-item, without the dmg
    TMI: game crashes after giving a Slope-block
    /item,/i,/give: same as TMI
    BackupPlugin: Backups all SlopeBlocks and Slopes in Chests
    RemoteRestartToolkit: Linux: all ok; windows: doesn't find KSlopes.jar
    /clearinventory doesnt remove the new blocks (from defaultCommands)

    Ehm, the 16bit entity pack mod download is currently not working. And since it is needed for the mod to work on the server, could you fix that, please? Or am I misunderstanding you and is it unreleased at the moment?

    Hmmm where to put the startup.txt now with the New Version? Tried the folder where the bukkit.jar is, ICPluginsfolder,Itemcraftfolder in bukkitfolder. Installation and Usage doesnt say something about it.

    ICPlugins. Should work there. In fact it should autocreate it there.

    When you're planning to add /ic give function? Also I am curious weather anyone is going to try to make Planes mod compatible with IC?

    And for the info asdaarg, I have been very successful as well on developing my mod, I'm done with Chair, Stool, Table and 1 Legged Table models, now have to retexture them. Moving on to light blocks - lanterns, lamps etc.. :)

    /ic give function hmm, I'd have to implement a separate plugin for that since itemcraft is no longer a plugin (to avoid being reloaded) I'll put up a link to SimpleGive meanwhile.

    Planes mod, should probably be easy to translate now that i've got the framework in place with mo's creatures. But at the moment going to add the missing optional stuff in fancypack since a lot of people have been asking for it.

    I look forward to seeing your new textures :)

    Hi! I would really love to see IndrustrialCraft in SMP, I hope someone would port it to ItemCraft :).
  23. Is this some horribly cruel joke or did you just make this the best mode ever,
    i cant really understand, mo creatures really, are we dreaming ?

    Ok dont try to create the ICPlugins Folder yourself. Just let it generate itsself. That was the reason the startup didnt work.
    I installed MoCreatures. I logged in and saw one of the new Creatures (Boar) and a new Bird. Then the Server crashed with this Error:

    Tried it 3 more Times but the Server kept crashing.
    I ran the Server without any Plugins. Just Itemcraft and Mocreatures. Error remains.
    After a few trys i find that there are almost no Creatures at all. I can run around a bit, but after some Time the Server crashes. Maybe when it tries to spawn a Mob?

    CB version? 138 is off the wall place for an error to occur.
    Edit: No it isn't, my source is a bit out of date.. hmm
  30. No water mobs, and no ogres and wraiths, why ?
