[SOLVED][1.19.4] How to order/place mod tabs inside the inventory?

[JimiIT92]

In my mod I add several new creative tabs, and I want them to be displayed in a specific order. Specifically, I register these tabs inside the CreativeModeTabEvent.Register event

@SubscribeEvent
public static void register(CreativeModeTabEvent.Register event) {
  BUILDING_BLOCKS = registerTab(event, "building_blocks", () -> new ItemStack(BLBlocks.RUBY_BLOCK.get()));
  COLORED_BLOCKS = registerTab(event, "colored_blocks", () -> new ItemStack(BLBlocks.YELLOW_CONCRETE_STAIRS.get()));
  NATURAL = registerTab(event, "natural", () -> new ItemStack(BLBlocks.HOLLOW_BIRCH_LOG.get()));
  FUNCTIONAL = registerTab(event, "functional", () -> new ItemStack(Items.PAINTING));
  REDSTONE = registerTab(event, "redstone", () -> new ItemStack(BLBlocks.COPPER_BUTTON.get()));
  TOOLS = registerTab(event, "tools", () -> new ItemStack(BLItems.EMERALD_PICKAXE.get()));
  COMBAT = registerTab(event, "combat", () -> new ItemStack(BLItems.KATANA.get()));
  FOOD_AND_DRINK = registerTab(event, "food_and_drink", () -> new ItemStack(BLItems.SASHIMI.get()));
  INGREDIENTS = registerTab(event, "ingredients", () -> new ItemStack(BLItems.RUBY.get()));
  SPAWN_EGGS = registerTab(event, "spawn_eggs", () -> new ItemStack(BLItems.COPPER_GOLEM_SPAWN_EGG.get()));
}

private static CreativeModeTab registerTab(CreativeModeTabEvent.Register event, String name, Supplier<ItemStack> iconSupplier) {
  return event.registerCreativeModeTab(new ResourceLocation(BlazersMod.MOD_ID, name),
                                       builder -> builder
                                       .icon(iconSupplier)
                                       .title(Component.translatable("itemGroup." + BlazersMod.MOD_ID + "." + name))
                                       .build());
}

and I thought they were displayed in this order, so the first mod tab would be building blocks, the next would be colored blocks etc...
However when I load the game they are misplaced. Specifically the first tab I see is the mod's spawn eggs tab, which is the last one registered, than the mod's ingredients tab and then the tools tabs, so isn't in the reverse registration order. If I intercept the CreativeModeTabEvent.BuildContents event to see when those tabs are populated I get the same wrong ordering, so it makes sense that in game they are ordered like this. Do I need to specify something to make them ordered in the same order as they are registered?

Maybe? https://github.com/MinecraftForge/MinecraftForge/blob/6e1de81ff5b94ec72ffbb5a243bf6f41d88e932b/src/main/java/net/minecraftforge/event/CreativeModeTabEvent.java#L77

Thank you, that worked

Could you show final code?

Sure, the only difference is that I'm now passing the previous tab to the method I use to register all my tabs. So now I have this
 

BUILDING_BLOCKS = registerTab(event, "building_blocks", CreativeModeTabs.SPAWN_EGGS, () -> new ItemStack(BLBlocks.RUBY_BLOCK.get()));
COLORED_BLOCKS = registerTab(event, "colored_blocks", BUILDING_BLOCKS,()  -> new ItemStack(BLBlocks.YELLOW_CONCRETE_STAIRS.get()));
NATURAL = registerTab(event, "natural", COLORED_BLOCKS, () -> new ItemStack(BLBlocks.HOLLOW_BIRCH_LOG.get()));
FUNCTIONAL = registerTab(event, "functional", NATURAL, () -> new ItemStack(Items.PAINTING));
REDSTONE = registerTab(event, "redstone", FUNCTIONAL, () -> new ItemStack(BLBlocks.COPPER_BUTTON.get()));
TOOLS = registerTab(event, "tools", REDSTONE, () -> new ItemStack(BLItems.EMERALD_PICKAXE.get()));
COMBAT = registerTab(event, "combat", TOOLS, () -> new ItemStack(BLItems.KATANA.get()));
FOOD_AND_DRINK = registerTab(event, "food_and_drink", COMBAT, () -> new ItemStack(BLItems.SASHIMI.get()));
INGREDIENTS = registerTab(event, "ingredients", FOOD_AND_DRINK, () -> new ItemStack(BLItems.RUBY.get()));
SPAWN_EGGS = registerTab(event, "spawn_eggs", INGREDIENTS, () -> new ItemStack(BLItems.COPPER_GOLEM_SPAWN_EGG.get()));

where I pass the previous tab to all the registerTab methods.
So my register tab method now simply adds the provided the tab to the "afterTab" list parameter provided to the registerCreativeModeTab function

private static CreativeModeTab registerTab(CreativeModeTabEvent.Register event, String name, CreativeModeTab afterTab, Supplier<ItemStack> iconSupplier) {
  return event.registerCreativeModeTab(new ResourceLocation(BlazersMod.MOD_ID, name),
                                       List.of(),
                                       List.of(afterTab),
                                       builder -> builder
                                       .icon(iconSupplier)
                                       .title(Component.translatable("itemGroup." + BlazersMod.MOD_ID + "." + name))
                                       .build());
}

It would be cool if the ordering was automatic like it was before, but I guess is not the end of the world to provide an extra parameter 😅
