@SubscribeEvent public void onLivingEntityDrops(LivingDropsEvent event) { LOGGER.info("DROP"); if (!(event.getEntityLiving() instanceof PlayerEntity)) return; BlockPos bedPos; try { bedPos = ((PlayerEntity)event.getEntityLiving()).getBedPosition().get(); } catch (NoSuchElementException e) { bedPos = new BlockPos(0, event.getEntityLiving().getPosition().getY(), 0); } World worldIn = event.getEntityLiving().getEntityWorld(); final IItemHandler[] nowHandler = new IItemHandler[1]; worldIn.setBlockState(bedPos, Blocks.BARREL.getDefaultState()); TileEntity barrelContainer = worldIn.getTileEntity(bedPos); IItemHandler itemhandler; nowHandler[0] = null; barrelContainer.getCapability(CapabilityItemHandler.ITEM_HANDLER_CAPABILITY).ifPresent(new NonNullConsumer <IItemHandler>() { @Override public void accept(IItemHandler ih) { nowHandler[0] = ih; } }); while (nowHandler[0] == null) {}; itemhandler = nowHandler[0]; int slot = 0; for (ItemEntity item : event.getDrops()) { LOGGER.info("drop"); ItemStack leftItemsStack = itemhandler.insertItem(slot, item.getItem().copy(), false); if (!leftItemsStack.equals(ItemStack.EMPTY)) { bedPos = bedPos.north(); worldIn.setBlockState(bedPos, Blocks.BARREL.getDefaultState()); barrelContainer = worldIn.getTileEntity(bedPos); itemhandler = nowHandler[0]; slot = 0; } slot++; } } Now it raises NullPointerException.

I have written the following code based on a related question: final IItemHandler[] nowHandler = new IItemHandler[1]; world.setBlockState(pos, Blocks.CHEST.getDefaultState()); TileEntity chestTileEntity = worldIn.getTileEntity(pos); IItemHandler itemHandler; nowHandler[0] = null; chestTileEntity.getCapability(CapabilityItemHandler.ITEM_HANDLER_CAPABILITY).ifPresent(new NonNullConsumer <IItemHandler>() { @Override public void accept(IItemHandler ih) { nowHandler[0] = ih; } }); while (nowHandler[0] == null) {}; itemhandler = nowHandler[0]; itemHandler.insertItem(1, new ItemStack(Items.SOME_ITEM, 1), false); // also I don't understand what "bool simulate" does But it doesn't work. Chest spawns, but there are no items in it. (There are no errors in LOG).

How exactly do I need to use it?

I need to spawn a chest with some items. I have these variables: PlayerEntity player; World world; BlockPos pos; ItemEntity[] items; // they are assigned, but I don't show the assignments here. I need to create a chest (or a barrel, or a shulker box) in world "world" at position "pos" with items "items". How can I do that? P.S. my minecraft forge version is 1.15.2.

Thanks! Didn't know about that. In survival mode it is fully working.

It logs "RIGHT CLICK".

It doesn't work somewhy. No errors and no item.

In older versions of Minecraft, the World.spawnEntityInWorld method could be used in order to spawn dropped ItemEntity like that (If I'm not misunderstanding): ItemEntity item = new ItemEntity(world, player.getPosition().getX(), player.getPosition().getY(), player.getPosition().getZ(), new ItemStack(Items.SOME_ITEM, QUANTITY)); world.spawnEntityInWorld(item); But in newer version, there is no such method. So, what's the alternative to that which works in newer versions of Minecraft?
