It finally worked! Thank you so much! if (event.getTab() == CreativeTabInit.BASE_TAB) { for (RegistryObject<Item> item : ITEMS.getEntries()) { event.accept(item.get()); } }

The following code worked but added all minecraft blocks and items to my creative tab. for (Item item : ForgeRegistries.ITEMS.getValues()) { if (new ItemStack(item.asItem()).getCount() == 1) { event.accept(item.asItem()); } } Is there any way I can filter them out?

The following is written in the main java class: public void addCreative(CreativeModeTabEvent.BuildContents event) { if (event.getTab() == CreativeTabInit.BASE_TAB) { for (Item item : ForgeRegistries.ITEMS.getValues()) { event.accept(item.asItem()); } for (Block block : ForgeRegistries.BLOCKS.getValues()) { event.accept(block.asItem()); } } } The following is written in the constructor of the class: modEventBus.addListener(this::addCreative); The following is the crash report: ---- Minecraft Crash Report ---- // Why did you do that?

Is there a more efficient way of accepting mod items and blocks into a creative tab? I've tried the following code: for (Item item : ForgeRegistries.ITEMS.getValues()) { event.accept(item.asItem()); } for (Block block : ForgeRegistries.BLOCKS.getValues()) { event.accept(block.asItem()); } but the game crashes the second I enter inventory. I think it's a problem with the stack size being over 1 as stated in the crash report. Any help?
