Hi

 

Almost certainly you are registering an item that you haven't instantiated yet (i.e. using new() ).

at com.James.item.MItems.registerItem(MItems.java:45)

 

These links will help you understand how to troubleshoot this type of error yourself.  It will save you an awful of time and frustration...

I need the see your src, specifically MyItems src.

Also put the crash report in code tags, it makes it easier to read.

 

I removes some of the codes that i dont need. So here it is.

 

 

package com.James.item;

 

import com.James.blocks.MBlocks;

import com.James.creativetabs.MCreativeTabs;

import com.James.lib.RefStrings;

 

import cpw.mods.fml.common.registry.GameRegistry;

import net.minecraft.creativetab.CreativeTabs;

import net.minecraft.item.Item;

import net.minecraft.item.Item.ToolMaterial;

import net.minecraftforge.common.util.EnumHelper;

 

public class MItems {

public static void mainRegistry(){

initializeItem();

registerItem();

}

 

public static ToolMaterial persitetool = EnumHelper.addToolMaterial("Persite Tool", 3, 2000, 16.5f, 4.5f, 10);

 

public static Item persitepick;

public static Item persiteaxe;

public static Item persitesword;

public static Item persitespade;

public static Item persitehoe;

 

public static void initializeItem(){

persitepick = new persitepick(persitetool).setUnlocalizedName("persitepick").setCreativeTab(MCreativeTabs.tabTools).setTextureName(RefStrings.MODID + ":persitepick");

persiteaxe = new persiteaxe(persitetool).setUnlocalizedName("persiteaxe").setCreativeTab(MCreativeTabs.tabTools).setTextureName(RefStrings.MODID + ":persiteaxe");

persitesword = new persitesword(persitetool).setUnlocalizedName("persitesword").setCreativeTab(MCreativeTabs.tabTools).setTextureName(RefStrings.MODID + ":persitesword");

persitespade = new persitespade(persitetool).setUnlocalizedName("persitespade").setCreativeTab(MCreativeTabs.tabTools).setTextureName(RefStrings.MODID + ":persitespade");

persitehoe = new persitehoe(persitetool).setUnlocalizedName("persitehoe").setCreativeTab(MCreativeTabs.tabTools).setTextureName(RefStrings.MODID + ":persitehoe");

}

 

public static void  registerItem(){

GameRegistry.registerItem(persitepick, persitepick.getUnlocalizedName());

GameRegistry.registerItem(persiteaxe, persiteaxe.getUnlocalizedName());

GameRegistry.registerItem(persitesword, persitesword.getUnlocalizedName());

GameRegistry.registerItem(persitespade, persitespade.getUnlocalizedName());

GameRegistry.registerItem(persitehoe, persitehoe.getUnlocalizedName());

}

I need your updated crash report as well. And put it in a code block otherwise it just fills up the entire page.

 

The reg crash IS the updated crash.

 

package com.James.item;

import com.James.creativetabs.MCreativeTabs;
import com.James.lib.RefStrings;

import cpw.mods.fml.common.registry.GameRegistry;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.item.Item;
import net.minecraft.item.Item.ToolMaterial;
import net.minecraftforge.common.util.EnumHelper;

public class MItems {
   public static void mainRegistry(){
       initializeItem();
       registerItem();
   }
   
   public static ToolMaterial persitetool = EnumHelper.addToolMaterial("Persite Tool", 3, 2000, 16.5f, 4.5f, 10);

   public static Item persitepick;
   public static Item persiteaxe;
   public static Item persitesword;
   public static Item persitespade;
   public static Item persitehoe;
   
   public static void initializeItem(){
      persitepick = new persitepick(persitetool).setUnlocalizedName("persitepick").setCreativeTab(MCreativeTabs.tabTools).setTextureName(RefStrings.MODID + ":persitepick");
      persiteaxe = new persiteaxe(persitetool).setUnlocalizedName("persiteaxe").setCreativeTab(MCreativeTabs.tabTools).setTextureName(RefStrings.MODID + ":persiteaxe");
      persitesword = new persitesword(persitetool).setUnlocalizedName("persitesword").setCreativeTab(MCreativeTabs.tabTools).setTextureName(RefStrings.MODID + ":persitesword");
      persitespade = new persitespade(persitetool).setUnlocalizedName("persitespade").setCreativeTab(MCreativeTabs.tabTools).setTextureName(RefStrings.MODID + ":persitespade");
      persitehoe = new persitehoe(persitetool).setUnlocalizedName("persitehoe").setCreativeTab(MCreativeTabs.tabTools).setTextureName(RefStrings.MODID + ":persitehoe");
   }
   
   public static void  registerItem(){
      GameRegistry.registerItem(persitepick, persitepick.getUnlocalizedName());
      GameRegistry.registerItem(persiteaxe, persiteaxe.getUnlocalizedName());
      GameRegistry.registerItem(persitesword, persitesword.getUnlocalizedName());
      GameRegistry.registerItem(persitespade, persitespade.getUnlocalizedName());
      GameRegistry.registerItem(persitehoe, persitehoe.getUnlocalizedName());
   }

The reg crash IS the updated crash.

 

That is impossible. Either you didn't send the entire src file or you sent an outdated version That crash report specifically states that the issue is in line 45 but your code only goes to line 42. Please re-run it and re-submit your crash report.

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

 

1.12 -> 1.13 primer by williewillus.

 

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.

Hi.

 

I guess you didn't try what I suggested?

 

The crash is on your line 45:

GameRegistry.registerItem(electricshard, electricshard.getUnlocalizedName());

 

A null pointer exception here means electricshard is null.  If you're not keen to learn about the debugger, you can also check this using this command:

 

System.out.println("electricshard:" + String.valueOf(electricshard));

GameRegistry.registerItem(electricshard, electricshard.getUnlocalizedName());

 

 

electricshard is set here

33:

electricshard = new Item ().setUnlocalizedName("electricshard").setCreativeTab(MCreativeTabs.tabItems).setTextureName(RefStrings.MODID + ":electricshard").getItemFromBlock(MBlocks.electrico);

 

Something in this line must be setting electricshard to null.

Hint - I think you have misunderstood how to use this method correctly.  When you register a block, it automatically registers an ItemBlock (extends Item) for you as well.  You can use this method to retrieve it, but you don't need all the new Item() since it is a static method, i.e. you can write Item.getItemFromBlock.  The block must have been instantiated and registered already.

    public static Item getItemFromBlock(Block p_150898_0_)
    {
        return getItemById(Block.getIdFromBlock(p_150898_0_));
    }
