Hello, I am new to modding in Minecraft.

 

After creating a few test blocks and a TileEntity I wanted to test my mod to see if things were working alright. However when I loaded up the game in Eclipse the game crashed and I got this error, and I cannot figure out what the problem is:

It should be noted that I am following this tutorial to learn to mod: https://wiki.mcjty.eu/modding/index.php/Main_Page

 

I believe the problem is in CommonProxy, so here is what that looks like:

package com.benthom123.test.proxy;

import java.io.File;

import com.benthom123.test.Config;
import com.benthom123.test.ModBlocks;
import com.benthom123.test.ModItems;
import com.benthom123.test.modClass;
import com.benthom123.test.blocks.FirstBlock;
import com.benthom123.test.blocks.datablock.DataTileEntity;
import com.benthom123.test.items.FirstItem;

import net.minecraft.block.Block;
import net.minecraft.item.Item;
import net.minecraft.item.ItemBlock;
import net.minecraftforge.common.config.Configuration;
import net.minecraftforge.event.RegistryEvent;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.event.FMLInitializationEvent;
import net.minecraftforge.fml.common.event.FMLPostInitializationEvent;
import net.minecraftforge.fml.common.event.FMLPreInitializationEvent;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;
import net.minecraftforge.fml.common.registry.GameRegistry;

@Mod.EventBusSubscriber
public class CommonProxy {
	// Config instance
    public static Configuration config;

    public void preInit(FMLPreInitializationEvent e) {
        File directory = e.getModConfigurationDirectory();
        config = new Configuration(new File(directory.getPath(), "modtut.cfg"));
        Config.readConfig();
    }
    public void init(FMLInitializationEvent e) {
    	 if (config.hasChanged()) {
             config.save();
         }
    }

    public void postInit(FMLPostInitializationEvent e) {
    }

    @SubscribeEvent
    public static void registerBlocks(RegistryEvent.Register<Block> event) {
    	 event.getRegistry().register(new FirstBlock());
    	 GameRegistry.registerTileEntity(DataTileEntity.class, modClass.MODID + "_datablock");
    }

    @SubscribeEvent
    public static void registerItems(RegistryEvent.Register<Item> event) {
    	  event.getRegistry().register(new ItemBlock(ModBlocks.SmoothObsidian).setRegistryName(ModBlocks.SmoothObsidian.getRegistryName()));
    	  event.getRegistry().register(new FirstItem());
    	  event.getRegistry().register(new ItemBlock(ModBlocks.dataBlock).setRegistryName(ModBlocks.dataBlock.getRegistryName()));
    }

           
}

 

 

if another class is the issue, here is the entire project on GitHub: https://github.com/InterdimensionalCat/src

 

Any help would be appreciated!

 

EDIT: It looks like this line of code specifically in CommonProxy is the issue:

  event.getRegistry().register(new ItemBlock(ModBlocks.SmoothObsidian).setRegistryName(ModBlocks.SmoothObsidian.getRegistryName()));

Edited October 25, 20177 yr by InterdimensionalCat

public static final String MODID = "btm";

 

@ObjectHolder("modClass:SmoothObsidian")

public static FirstBlock SmoothObsidian;

 

Hmmm
