You are not saving the ItemStacks to NBT.

How, when there not slot?

Where are you saving the stacks?

What? Sorry my English is bad.

Where is the object located that contains the items you want to save in the pan?

I saved everything you need, I just need to save item whether it is in the pan or not.

Can you show me the ItemHandler class, please?

Perhaps this you wonder from ItemHandler.

 

 

 

    public static Item DfPancakes = new Item().setUnlocalizedName("dough_for_pancakes").setCreativeTab(Main.FarmCraft2Tab).setContainerItem(Items.BOWL);

    public static Item Pancakes = new ItemFood(4, false).setUnlocalizedName("pancakes").setCreativeTab(Main.FarmCraft2Tab);

 

 

I would suggest you to not do that the way you are doing it now, it just doesn't really make sense. You should instead create an internal inventory for your pan and use that to handle the stacks. This inventory can then be written to and read from NBT.

Yeah, I know it, too. But I do not know how to do that when you click on item with an item, the item is put into the slot.

Override the method onBlockActivated in your Block class and if the held item can be cooked in the pan get your TileEntity, get the inventory inside of it and place the ItemStack in the inventory.

    public boolean onBlockActivated(World world, BlockPos pos, IBlockState state, EntityPlayer player, EnumHand hand, @Nullable ItemStack heldItem, EnumFacing side, float hitX, float hitY, float hitZ)
    {
       TileEntityPan te = (TileEntityPan) world.getTileEntity(pos);
       
       if(!world.isRemote){
           if(heldItem != null && heldItem.getItem().equals(ItemHandler.DfPancakes) && !te.isBurning())
           {
               heldItem.stackSize--;
           } else{
        	   player.openGui(Main.MODID, FC2_GuiHandler.PANGUI, world, pos.getX(), pos.getY(), pos.getZ());
           }
       }
       return true;
    }

 

And now I'm finished. I do not know how to put the item into the slot.

    public boolean onBlockActivated(World world, BlockPos pos, IBlockState state, EntityPlayer player, EnumHand hand, @Nullable ItemStack heldItem, EnumFacing side, float hitX, float hitY, float hitZ)

    {

      TileEntityPan te = (TileEntityPan) world.getTileEntity(pos);

      Container container = te.createContainer(player.inventory, player);

      Slot slot = (Slot)container.inventorySlots.get(0);

     

      if(!world.isRemote){

          if(heldItem != null && heldItem.getItem().equals(ItemHandler.DfPancakes) && !te.isBurning())

          {

              slot.putStack(heldItem);

              heldItem.stackSize--;

          } else{

          player.openGui(Main.MODID, FC2_GuiHandler.PANGUI, world, pos.getX(), pos.getY(), pos.getZ());

          }

      }

      return true;

    }

 

But slot.putStack(heldItem); give me whole stack. But I only want one item, no stack.

You do know about stack splitting, yes?

What? Probably no.

splitStack

ItemStack newstack = stack.split(1);

I figured it out myself.

 

    public boolean onBlockActivated(World world, BlockPos pos, IBlockState state, EntityPlayer player, EnumHand hand, @Nullable ItemStack heldItem, EnumFacing side, float hitX, float hitY, float hitZ)
    {
       TileEntityPan te = (TileEntityPan) world.getTileEntity(pos);
       Container container = te.createContainer(player.inventory, player);
       Slot slot = (Slot)container.inventorySlots.get(0);
       
       if(!world.isRemote){
           if(heldItem != null && heldItem.getItem().equals(ItemHandler.DfPancakes) && !te.isBurning())
           {
        	   ItemStack is = heldItem.splitStack(1);
               slot.putStack(is);
           } else{
        	   player.openGui(Main.MODID, FC2_GuiHandler.PANGUI, world, pos.getX(), pos.getY(), pos.getZ());
           }
       }
       return true;
    }

 

Thanks.

"I have a problem with render" doesn't give us any clue about what's not working correctly? Is it not rendering? Is it rendering weird? Is it upside down? Please, be more specific.

The error is in the Check(). Minecraft always crash.

There's only 1 thing in the Check method that can be

null

(I'm guessing it's an NPE). Figure it out and do a proper

null

-check.

    public boolean Check(){  	
    	if(panItemStacks[2].getItem() == ItemHandler.Pancakes)

    		return true;
