I went through the crash report and found this.

java.lang.NullPointerException: Can't add null-object to the registry, name FirstMod:Firestone.

 

help would be appreciated

We need more than that to go on.

 

The only thing I can tell from that is that you're trying to add null to the registry, maybe you're doing "GameRegistry.registerItem(null,someStringName);" ?

Might your crash be in any way related to this?

 

Except that item has to be lowercase.

For blocks use "tile".

Ok what he said worked and i launched MC but the block is not there. I checked my code and found that i had forgot to register the block so i put

GameRegistry.registerBlock(Firestone);

and it had an error, i checked quick fixes and it wanted to change it to make it

GameRegistry.registerBlock(Firestone, null);

 

this is causing my MC to crash again.

 

Where I told you

GameRegistry.registerBlock(Firestone);

and it had an error, i checked quick fixes and it wanted to change it to make it

GameRegistry.registerBlock(Firestone, null);  <-- MAKE THIS NOT NULL

this is causing my MC to crash again.

 

See above

 

And then

 

I have to put something there. I can't just leave it blank, I was wanting to know what to put there

It's a fuckin' string.  What do you want to call the block?  It can be anything (as long as you don't use something that's been used before).  Seriously.  Not.  That.  Hard.

here is my main.

package jibberish.firstmod.common;

 

import jibberish.firstmod.block.BlockFirestone;

import net.minecraft.block.Block;

import net.minecraft.block.material.Material;

import cpw.mods.fml.common.Mod;

import cpw.mods.fml.common.SidedProxy;

import cpw.mods.fml.common.event.FMLInitializationEvent;

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

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

 

@Mod(modid = "FirstMod", name = "First Mod", version = "1.0.0 Alpha")

 

public class FirstMod {

@SidedProxy(clientSide = "jibberish.firstmod.client.ClientProxy", serverSide = "jibberish.firstmod.commpn.CommonProxy")

public static CommonProxy proxy;

 

public static Block Firestone = new BlockFirestone(2000, Material.glass).setUnlocalizedName("firestone");

 

 

public void load(FMLInitializationEvent event){

proxy.registerRenderInformation();

}

 

public FirstMod() {

 

GameRegistry.registerBlock(Firestone, "Firestone");

 

}

}

 

and here is my block class

package jibberish.firstmod.block;

 

import net.minecraft.block.Block;

import net.minecraft.block.material.Material;

import net.minecraft.client.renderer.texture.IIconRegister;

import net.minecraft.creativetab.CreativeTabs;

 

public class BlockFirestone extends Block {

 

private String unlocalizedName;

public Block setBlockName(String Firestone)

{

this.unlocalizedName = Firestone;

return this;

}

public BlockFirestone(int par1, Material par2Material){

super(par2Material);

this.setCreativeTab(CreativeTabs.tabBlock);

this.setLightLevel(0.9F);

this.setHardness(4);

this.setResistance(5);

}

public void registerIcons(IIconRegister iconRegister) {

blockIcon = iconRegister.registerIcon("FirstMod:Firestone");

}

public Block setUnlocalizedName(String Firestone) {

return null;

}

 

}

 

 

Oh and i understand this might not be very good code. I've been following a 1.6.4 tutorial so ive had to convert some things.

Ohhh ok.. thanks

 

Also,

 

public BlockFirestone(int par1, Material par2Material){

 

You can drop the "int par1" as you're not using it.  That used to be the block ID, but as block IDs are no longer A Thing, you don't need it.
