Hello,

first I use forge-1.10.2-12.18.1.2010

so when I want to use addSubstitutionAlias like previous versions, game compile,

but when I join a world the game freeze : the cause is a duplication of StatBase.

I think is a bug of forge.

Logs, Code, etc...

my code :

public static void overrideItem(Item itemold, Item itemnew) {
    	try {
    		itemold.setCreativeTab(null);
    		String name = ((ResourceLocation)Item.REGISTRY.getNameForObject(itemold)).toString();
    		System.out.println("OVERRIDE: " + name);
    		itemnew.setUnlocalizedName(itemold.getUnlocalizedName().replaceFirst("item.", ""));
	GameRegistry.addSubstitutionAlias((name), GameRegistry.Type.ITEM, itemnew);

} catch (Exception e) {
		e.printStackTrace();
}
}

for example :

overrideItem(Items.IRON_HELMET, new ItemArmorMod(ItemArmor.ArmorMaterial.IRON, 2, EntityEquipmentSlot.HEAD));
overrideItem(Items.IRON_CHESTPLATE, new ItemArmorMod(ItemArmor.ArmorMaterial.IRON, 2, EntityEquipmentSlot.CHEST));
overrideItem(Items.IRON_LEGGINGS, new ItemArmorMod(ItemArmor.ArmorMaterial.IRON, 2, EntityEquipmentSlot.LEGS));
overrideItem(Items.IRON_BOOTS, new ItemArmorMod(ItemArmor.ArmorMaterial.IRON, 2, EntityEquipmentSlot.FEET));

error :

Thank you for reply

However you're registering your object is wrong, its getting a duplicate name instead of using your items registry name.

Dont know if that better, but same error... 

String name = ((ResourceLocation)Item.REGISTRY.getNameForObject(itemold)).toString();
String newName = name.replaceFirst("minecraft:", "");
itemnew.setUnlocalizedName(newName);
itemnew.setRegistryName(new ResourceLocation(MFRMod.MODID, newName));
GameRegistry.addSubstitutionAlias(name, GameRegistry.Type.ITEM, itemnew);

 

freezing at loading :

 

and same error finished by :

[15:46:19] [server thread/INFO] [FML]: The state engine was in incorrect state ERRORED and forced into state SERVER_STOPPED. Errors may have been discarded.

[15:46:19] [server thread/INFO] [FML]: The state engine was in incorrect state ERRORED and forced into state AVAILABLE. Errors may have been discarded.

Same here, same error. Though it has been like this for a long time.

 

I firmly believe that addSubstitutionAlias is somehow non-functionning for some people.
