On the RegistryEvent.Register<Item> event I made a substitution alias: GameRegistry.addSubstitutionAlias("minecraft:map", GameRegistry.Type.ITEM, myEmptyMap); where myEmptyMap is an instance of com.example.MyEmptyMap that extends net.minecraft.item.ItemEmptyMap.

In The constructor of net.minecraft.item.ItemEmptyMap there is the call to setCreativeTab(CreativeTabs.MISC); so I left my constructor empty.

Why in the misc tab there are 2 minecraft:map items? How can i remove one?

 

Thx

 

I reported this here, cpw isn't intending to fix it.

 

You can probably set the vanilla Item's creative tab to null before you substitute it to prevent it from showing up in the creative menu.

As cpw said this is a sided effect so the method addSubstitutionAlias must be called only in server side. The solution is to  remove it from client proxy.

Thx

But if you have to overwrite a method of the item in both sides? Let's say that you want to overwrite onItemRightClick?

He said it's a side effect, not a sided effect.

 

This has nothing to do with the client/server sides.

Sry for my bad english

I tried this but it does not work:

 

@SubscribeEvent

public void onRegisterEvent(RegistryEvent.Register<Item> event) {

   Items.MAP.setCreativeTab(null);

    try {

             GameRegistry.addSubstitutionAlias("minecraft:map", GameRegistry.Type.ITEM, MyMod.myEmptyMap);

         } catch (ExistingSubstitutionException e) {

        e.printStackTrace();

    }

}

 

Still 2 items in the misc tab.

Looking into this further, the original Item is never returned by the registry iterator used in CreativeTabs#displayAllRelevantItems; the substitution is returned twice. This explains why setting the creative tab of the original Item doesn't work.

 

I'm not sure if there's any way to fix this.
