[Solved][1.19.4] Automatically add items and blocks into costume tab using addCreative() but excluding some

[perromercenary00]

i need some headstorm here 

1.19.4 change the way to add the items and blocks to  custome mod tabs now you have to use an event an manually add every item or block and thas a pain in <t> coze i have to many blocks 
soo i tell to miself what if i use a foor loop whith "DeferredRegister<Item> ITEMS" thing and it works it drops everything into the tab and i dont have to manually keep track of it if change something

 

Spoiler

				
			//agregar items y block a las tabs
		private void addCreative(CreativeModeTabEvent.BuildContents event)
		{
		    Item actualItem = null;
		    Block actualBlock = null;
		    int count = 0;
		
		    if( event.getTab() == tab.MERCBLKTAB ){
		        for ( RegistryObject<Item> ResourceKey : ItemInit.ITEMS.getEntries()) {
		            actualItem = ResourceKey.get();
		                if(!(actualBlock instanceof trampilla)) {
		                     event.accept(actualItem);
		                }
		            count++;
		        }
		    }
		}				
			

 

but i have some blocks and some items that are kinda metablocks/subitems basically the same block thing and i dont nedd/want them to be visible 

 

i try to filter them by class but dint works coze in this stage they are already converted to item block soo i cannot filter using instance of 

	if(!(actualBlock instanceof trampilla)) {
event.accept(actualBlock);
}
	

 

Sooo any idea how i can mark this items blocks to be excluded from the tab

Is your "actualItem" a BlockItem? Then see Block.byItem()

 

Otherwise we can't help you without more information.

If you want help, you need to post a project on github that reproduces your problem.

Incomplete information posted in the forums will likely just mean your question gets ignored.

You also know you can have different DeferredRegisters for different internal categories of your items?

e.g. psuedo code:

    // Real items that should be shown in creative tabs
    public static final DeferredRegister<Item> REAL_ITEMS = DeferredRegister.create(ForgeRegistries.ITEMS, MODID);
    public static final RegistryObject<Item> TEST = REAL_ITEMS.register("test", () -> new Item(new Item.Properties()));

    // Internal items the user shouldn't have direct access to
    public static final DeferredRegister<Item> META_ITEMS = DeferredRegister.create(ForgeRegistries.ITEMS, MODID);
    public static final RegistryObject<Item> META = META_ITEMS.register("meta", () -> new Item(new Item.Properties()));

ya it makes sense 

itemblock is a subclass of item 

and from itemblock the block can be retrieved

		    Item actualItem = null;
		    Block actualBlock = null;
		    int count = 0;
		    boolean RegistrarEste = false;
		
		    if( event.getTab() == tab.MERCBLKTAB ){
		        for ( RegistryObject<Item> ResourceKey : ItemInit.ITEMS.getEntries()) {
		            RegistrarEste = true;
		            actualItem = ResourceKey.get();
		
		            if((actualItem instanceof BlockItem)) {
		                BlockItem actualBlockItem = (BlockItem)actualItem;
		
		                    if(actualBlockItem.getBlock() instanceof trampilla) {//ignore all the trampillas
		                        RegistrarEste = false;
		                    }
		                }
		
		                if(RegistrarEste) {
		                    event.accept(actualItem);
		                }
		                count++;
		            }
		        }				
			}				
			

 

Thanks for your help again
