Inactive [MECH/DEV] ItemCraft 1.6.6 - Support for client mods in Bukkit [1060/1000]

ItemCraft
Version:1.6.6


Description:

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.

Features:

• 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:
    
    Code:

    java -Xmx1024M -Xms1024M -cp ItemCraft.jar;craftbukkit-0.0.1-SNAPSHOT.jar org.bukkit.craftbukkit.Main

  • Others:
    
    Code:

    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.

Can anybody solve my problem please?

 

Oh, it just had to be recompiled after changing Packet24, that explains why there was no difference in the code between the unmodified and modified mx.class. Works nicely now
Just one thing: Can you add a mob spawning command since (at least as far as I know) /spawnmob in Essentials won't spawn the extra mobs.

 

Try re-downloading it in say firefox, chrome at least got a fucked up cache.

 

How can I change the parameters for Mo Creatures (spawn rate, difficulty etc), this page has some information http://itemcraft.wikispaces.com/Tutorials but the mention of the old startup syntax is a bit confusing, is there a way to do the same thing with the new startup syntax or do I have to make a separate .ic file loaded with includeold that has all the parameters?

 

I'm not able to start this..
If I make a start.bat it just closes and no server is running...
what can i do?
I have win7 64bit and im using bukkit 818.

 

try this for your run.bat file

@ECHO OFF
SET BINDIR=%~dp0
CD /D "%BINDIR%"
"%ProgramFiles(x86)%\Java\jre6\bin\java.exe" -Xincgc -Xmx1G -cp ItemCraft.jar;craftbukkit-0.0.1-SNAPSHOT.jar org.bukkit.craftbukkit.Main
PAUSE

 

Hi,
How to disable the 16bit packet thingy, if i do it it says that:
false <-- Unknown Identifier "false setEntityIDPacketMod" @ line 5 col 5

I put it in init.ic.. is this wrong :O ?

 

Yes you can add this with the new Syntax too. But the way with the old Syntax works too.

 

Its an embarrassing bug. Try with 1.3.7

 

So, is there any possibility to add Mod like FINITE LIQUIDS?

 

This always baffles me a bit, does your server really run at 1gb of ram? Mine croaks if i dont give it at least 1.7gb.
Dont think it ever releases memory, tried to mess around with plugins, but no obvious perpetrator

 

Still doesnt work
anyone did it on another way?
or someone post his ItemCraft files

 

Mo creatures crash game when connect to server ... in single all ok...

 

@asdaarg

I know the plugins are not your problem but one of my users is having issues starting minecraft using a bin and jar I gave him. All my other users are fine. He is forced to use a .bat to run minecraft

Code:

java -Xms768m -jar "C:\Program Files\Minecraft\minecraft.jar"

If i go any higher it wont allocate the memory and or run.

Then when I start his MC with Modloader, AudioMod, MoCreatures, Kslopes, and Fancypack.. (yes this jar is tested and works on all my other users)... He gets some wierd errors in the command prompt and MC crashes.

Code:

[Props] Unable to open fancypack_core.properties!
Failed to load mod from "mod_FancyPack.class"

Then you see Kslops load just fine, Audio Mod initializes.. some open AL code then it

openAL initialized.
STOPPING!

thats when MC Crashes.

I have no idea. I had him delete his whole bin and use mine.. same avail..

Im using the 1.5_01 version as my server is not 1.6.6 due to me waiting on a Terrain Mod to become 1.6.6 compatible.

Any help for him would be greatly appreciated. Thank you in advance.

 

This needs a little clarification on what you are trying to achieve here. ItemCraft will not currently run without the 16bit entity.
You say you are trying to disable it ? and you say you put 'IT' in the init.ic, what 'IT' please ?

[Edit]
Apologies, I haven't been getting any errors using IC 1.3.6 - didn't know about it.

Have we any specs on this persons machine ? i.e. chip / ram / os

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Ok, another bug, try now with 1.3.8.

 

Hello, I have a little Minecraft Server and I want to add new item, I have download your (very good) plugin and he work fne with SuperSlopes (with craftbukkit 860) , but I want to add my custom item made with MCP, but I don't understand how I can translate my Mod (MCP) to the Itemcraft API.​

​

For exemple, I have 2 ***.java:​

The first mod_MyMod.java who content:​

​

Code:

package net.minecraft.src;
public class mod_MyMod extends BaseMod
{
public mod_MyMod()
{
ModLoader.RegisterBlock(myBloc);
ModLoader.AddRecipe(new ItemStack(myBloc, 1), new Object[]
{"#",Character.valueOf('#'), Block.dirt});
}
public static final Block myBloc = (new
BlockMyBloc(99,2)).setHardness(2.0F).setResistance(10F)
.setStepSound(Block.soundStoneFootstep);
public String Version()
{
return "1.5_01";
}
}

​

​

And the second BlockMyBlock;java:​

​

Code:

package net.minecraft.src;
import java.util.Random;
public class BlockMyBloc extends Block
{
public BlockMyBloc(int i, int j)
{
super(i, j, Material.rock);
}
public int idDropped(int i, Random random)
{
return Block.cobblestone.blockID;
}
}

​

​

​

This is just a exemple, this bloc is useless.​

This code work fine in solo with Modloader, but I want to translate this (exemple) to Itemcraft. Please can you help me? You will help all of my community!​

​

Sorry for grammar,synthax... I'am not English but I try to be comprehensible​

 

Hi Asdaarg,

First, you do some great job, keep continue
I come here because i have some trouble with ICMCreatures, i can't use any horse, i can ride it but i have no control on it, except if i hit him until death and when i get down i recevied the message "Disconnected by server - You moved too quickly".
And also i don't have any spawn of shark or dolphin in water but skuid are there(a lot in group), i use the method with the old startupsyntax for MoCreatures to control the spawn of the mob in case of but nothing : / in solo mode no problem with the mob water.
If you have any idea, Thks.

Bye (sorry for my english ...)

 

Mc blackscreens if you connect

 

intel [R] core [tm] 2 duo e4500 @2.2 ghz
2gb Ram
Windows Vista

 

How do I add it with the new syntax?

 

Dont know. Its quite complicated if you know nothing about Programming. Im just beginning to learn it.

@Marco:
Im trying to figure this out too. Im in the process of making a little Mod. Would be nice if i could add it to my Server someday. When i make some Progress i let you know.

 

This is a known bug :

There is an incompatibility between the "16 bit entity id packet mod" and the "Worldedit Client-side Interface" (which can be found here), can someone merge the class "mx.class" ?

Thanks.

 

These are known issues with Mo Creatures. It is what it is for now - water mobs don't appear, horses don't work properly and some of the other creatures (i.e. werewolf) don't appear. Your question has been raised before - all that can be said is that there is currently no fix available.

 

Asymetrikon:
I try too, if I make a mod who work with ItemCraft I will post how to do that on this topic/forum.

 

Well, that should be more than enough to run it. Since you have taken a working 'bin folder and put it onto this machine, then it narrows down to something wrong with the machine.
Options : Is the o/s compromised with either a Virus / Spam-ware - Does it have so many processes running that there is no memory left to run anything else ? Does it have on-board graphics which is sharing the actual ram, in which case, is the amount of ram being shared 'changable' in the bios - perhaps theres not enough ram being given to the on-board graphics - or perhaps too much ? Is he using java 6 ? Although in beta, I've been using Java 7 for a while now with no problems - available HERE. Perhaps your user could give this a try.
Hows the pagefile setting on this machine - could it be expanded to be a little bigger ?

It all seems very odd that everyone else can use it except one person (or one machine). At this point, one can only offer suggestions, which may or maynot be of assistance.
[Edit]
Unfortunately the java download site in read-only until next week due to maintainence, so no downloads at the moment.

Here is my current start params. for the java version of Minecraft :
java -server -Xms2048M -Xmx20484M -XX: ParallelGCThreads=2 -cp Minecraft.jar
net.minecraft.LauncherFrame

( There should no space beetween -XX: and the word ParallelGCThreads=2 - I've had to leave one because the P keeps getting changed to a smily face if I don't)

Your user will have to reduce the amount of memory to from 2048 to 1024, I also use the jdk version of java rather than the jre. The -server option will only work with the jdk version.
Again, the standard params. should work in almost all cases, so still thinking there is a problem with this persons machine, however, at this point, anything is worth a try.

 

Ok i see those known issues but i was not sure thats was thas was my case, now it confirmed.

For those that say they don't, werewolves, wraiths, and ogres do spawn if you set their spawn difficulty to 0.

 

Where is the 1.3.8 link? I tried downloading the link right under the bold "1.6.6" but when I try to run it the server fails to start and is saying the ItemCraft is version 1.3.3

EDIT: this is the link my browser shows http://tetragaming.com/asdaarg/ItemCraft/0/ItemCraft.jar

 

I updated to 1.6 today and noticed something.
I installed the Sphereworldplugin and made a skylands map with Multiverse too.
In both Worlds there is very little Water and the Landanimals from MoCreatures are much more frequent in this Worlds than in the normal ones. Its really noticable.
So maybe the low Spawnrates of the Landanimals has something to do with the not spawning Wateranimals?
When you use loud with the old startup you can see that you get spammed with Spawningerrors from Wateranimals in normal Worlds. In the Worlds with little Water you get very little Errors. So i thought maybe its related.
