    • @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.
    • If simulate is true it only simulates adding the ItemStack to the IItemHandler. Why? Why not just put this in the accept function?   Where is this code being called? Post all of it,
    • I'm having issues. I just installed Minecraft Forge on my Linux server, but every time I try to add mods the server crashes. I have the Recommended version of Forge installed. I download a mod and added it to the "Mods" Folder and it gives the same error no matter what the mod is. It works as long as I don't have any Mods in the Mods folder. Here's what happens when I try to start the server:   [16:59:13] [main/INFO] [cp.mo.mo.Launcher/MODLAUNCHER]: ModLauncher running: args [--gameDir, ., --launchTarget, fmlserver, --fml.forgeVersion,

    • Yes! That was the missing piece, thank you so much! I could have sworn that method was related to movement, not rendering, probably because the field it clears is also cleared in the doesNotBlockMovement method... I guess it's just by default that things which don't block movement aren't considered to be solid renders, either. Anyway, thanks again, I'm glad this is finally solved
    • 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).
