I hope someone can help me.

Would you please show your ModEnumMaterial.java sice it seems to crash on that.

 

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.

Ok I found my mistake. I simply had to put the ModEnumMaterial.initModEnumMaterial(); at te first place in the load function. thanks!

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
