Hello, I was working on my mod and I was following the tutorial at (http://www.minecraftforge.net/wiki/Basic_Modding) and I tried to run it and got this error.

I also have the code for here:

 

Soldiers_Mod.java:

package SoldierW518.Soldiers_Mod;

 

import cpw.mods.fml.common.Mod;

import cpw.mods.fml.common.Mod.Init;

import cpw.mods.fml.common.Mod.Instance;

import cpw.mods.fml.common.Mod.PostInit;

import cpw.mods.fml.common.Mod.PreInit;

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.network.NetworkMod;

 

@Mod(modid="Soldiers_Mod", name="Soldiers Mod", version="1.0")

@NetworkMod(clientSideRequired=true, serverSideRequired=false)

public class Soldiers_Mod {

 

@Instance("Soldiers_Mod")

    public static Soldiers_Mod instance;

 

@SidedProxy(clientSide="SoldierW518.Soldiers_Mod.Client", serverSide="SoldierW518.Soldiers_Mod.CommonProxy")

public static CommonProxy proxy;

 

@PreInit

public void preInit(FMLPreInitializationEvent event) {

 

}

 

@Init

public void load(FMLInitializationEvent event) {

proxy.registerRenderers();

}

 

@PostInit

public void postInit(FMLPostInitializationEvent event) {

 

}

 

}

 

CommonProxy.java:

 

package SoldierW518.Soldiers_Mod;

 

public class CommonProxy {

public static String ITEMS_PNG = "/SoldierW518/Soldiers_Mod/items.png";

public static String BLOCK_PNG = "/SoldierW518/Soldiers_Mod/block.png";

 

public void registerRenderers() {

 

}

}

 

ClientProxy.java:

 

package SoldierW518.Soldiers_Mod.Client;

 

import net.minecraftforge.client.MinecraftForgeClient;

import SoldierW518.Soldiers_Mod.CommonProxy;

 

public class ClientProxy extends CommonProxy{

 

@Override

public void registerRenderers() {

MinecraftForgeClient.preloadTexture(ITEMS_PNG);

MinecraftForgeClient.preloadTexture(BLOCK_PNG);

}

 

}

 

If anyone could help me out I would greatly appreciate it.

 

Thanks for Reading,

On your @SidedProxy

it is declared that it can't find the class named Client.class, which you have named ClientProxy.class.

Easy fix:                                                                  V V V V V V V  FIX RIGHT THERE

 

@SidedProxy(clientSide="SoldierW518.Soldiers_Mod.ClientProxy", serverSide="SoldierW518.Soldiers_Mod.CommonProxy")
   public static CommonProxy proxy;

 

Old Code:

@SidedProxy(clientSide="SoldierW518.Soldiers_Mod.Client", serverSide="SoldierW518.Soldiers_Mod.CommonProxy")
   public static CommonProxy proxy;

 

New Code:

@SidedProxy(clientSide="SoldierW518.Soldiers_Mod.ClientProxy", serverSide="SoldierW518.Soldiers_Mod.CommonProxy")
   public static CommonProxy proxy;

 

Thank you very much for showing me where I had an error in my code! But, this didn't fix it. I had to do this.

 

@SidedProxy(clientSide="SoldierW518.Soldiers_Mod.Client.ClientProxy", serverSide="SoldierW518.Soldiers_Mod.CommonProxy")

public static CommonProxy proxy;

 

Because my package that the ClientProxy was in was called "SoldierW518.Soldiers_Mod.Client.ClientProxy" but still Thank you SO much for at least showing me where I made a mistake which made me look at the code and figure out what I did wrong.

 

Thank you very much for reading,
