here it is:

 

package Launcraft.src;

 

import net.minecraftforge.common.EnumHelper;

import net.minecraft.item.EnumToolMaterial;

import net.minecraft.item.EnumArmorMaterial;

import net.minecraft.item.ItemStack;

 

public class ModEnumMaterial

{

    public static EnumToolMaterial COPPER;

public static EnumToolMaterial SILVER;

public static EnumToolMaterial GEMSTONE;

 

public static EnumArmorMaterial COPPERARMOR;

public static EnumArmorMaterial SILVERARMOR;

public static EnumArmorMaterial GEMSTONEARMOR;

   

    public static void initModEnumMaterial()

    {

COPPER = EnumHelper.addToolMaterial("COPPER", 2, 200, 4.0f, 5, 15);

SILVER = EnumHelper.addToolMaterial("SILVER", 2, 400, 5.0f, 6, 18);

GEMSTONE = EnumHelper.addToolMaterial("GEMSTONE", 2, 1500, 7.0f, 8, 22);

 

COPPERARMOR = EnumHelper.addArmorMaterial("COPPERARMOR", 12, new int[]{2, 5, 4, 1}, 12);

SILVERARMOR = EnumHelper.addArmorMaterial("SILVERARMOR", 18, new int[]{3, 7, 5, 2}, 12);

GEMSTONEARMOR = EnumHelper.addArmorMaterial("GEMSTONEARMOR", 30, new int[]{3, 8, 6, 3}, 25);

    }

}

Ahh I see, I think you just have to rename 'public static void initModEnumMaterial()' to 'public ModEnumMaterial()' since I think the reason that it crashes is that initModEnumMaterial() not gets called before there's a call to the ModItems class cousing it to not get assigned and couse a null pointer exception. Try it :)

I tried it but I get an error because I have to load it in the main File. But how can I make that? It has no init.

 

sorry if that question is dumb but I'm actually not very good with java.

You're doing it the hard way, just use enum helper to register a new enum(in 1 line of code) in your mod files init

"you seem to be THE best modder I've seen imo."
