Modding help: SP works, MP doesn't

Hi forum,

 

I'm getting started with Forge modding and want to start something minimap-like to check out the capabilities of Forge. I've already set up a basic skeleton that calls a hook when a Chunk is loaded (which looks very good so far to me!). That's pretty much what I wanted.

 

But it only works when I do singleplayer. As soon as I try to connect to a MP server, it instantly crashes the game:

Here's the basic mod code

 

package com.examplemapper;

import net.minecraft.world.chunk.Chunk;
import net.minecraftforge.common.MinecraftForge;
import cpw.mods.fml.common.Mod;
import cpw.mods.fml.common.Mod.EventHandler;
import cpw.mods.fml.common.Mod.Instance;
import cpw.mods.fml.common.SidedProxy;
import cpw.mods.fml.common.event.FMLInitializationEvent;
import cpw.mods.fml.common.event.FMLPostInitializationEvent;
import cpw.mods.fml.common.event.FMLPreInitializationEvent;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;

@Mod(modid = ExampleMapperMod.MODID, version = ExampleMapperMod.VERSION)
public class ExampleMapperMod {
public static final String MODID = "ExampleMapper";
public static final String VERSION = "0.01";

@Instance(ExampleMapperMod.MODID)
public static ExampleMapperMod instance;

@SidedProxy(clientSide = "com.examplemapper.ClientProxy", serverSide = "com.examplemapper.CommonProxy")
public static CommonProxy proxy;

@EventHandler
public void preInit(FMLPreInitializationEvent event) {
	proxy.preInit(event.getSuggestedConfigurationFile());
}

@EventHandler
public void load(FMLInitializationEvent event) {
	proxy.load();
}

@EventHandler
public void postInit(FMLPostInitializationEvent event) {
	proxy.postInit();
}
}

 

where the CommonProxy code is completely empty and the ClientProxy code just registeres my event handling class to the MinecraftForge.EVENT_BUS.

 

A side note: I cannot seem to find the JAR that is built for my mod. If I want to make a release, where would I find it?

 

Thanks for your help,

Henrik

    Aaaah! I see! Hadn't thought of that at all, thank you a lot.

     

    So since I don't want to dev on my remote server, how can I generate a JAR that I can include with my (production) Minecraft installation and drop into the mods/ directory of it?

     

    Cheers,

    Henrik
