Try this: Create a new package: data.minecraft.tags.blocks Put the tag files in there. I think that is what I did. What this theoretically does is it appends the file to the default minecraft tags. Just try it. Also make sure you create a new world while testing it. Testing it in an already created world will still make them decay.

Did you set up the folders properly? Remember the data folder does not go in assets. Show me your data folder setup.

Name one file logs, and another to leaves. And when it comes to minecraft tags, no you do not need to add them, just make sure replace is set to false.

Sorry for not marking my post solved but the issue here has to do with block tags: https://minecraft.gamepedia.com/Tag Your mod has to have a file tagging your leaves block as leaves and another another tagging your log block as a log. Or something to that affect. I will be updating my post soon.

How would I go about doing this?

Ok so I have: package com.kenneths_medieval_mod.objects.blocks.workstations.smelting_forge; import org.lwjgl.opengl.GL11; import com.kenneths_medieval_mod.KenmodMain; import net.minecraft.client.Minecraft;

Whats wrong?

Can you help me with this? I am not sure where you are getting your numbers in you blit function from but I can give you the GUI I created so you can help me get those numbers: There is a free program: https://pixlr.com/editor/ It allows you to see the coordinates of each pixel by hovering over the image.

where does the 40 come from in you blit function?

Im talking about the arrow and flame you see in the furnace gui...

I am so close to finishing my custom furnace yet this is the last obstacle I face. Any idea how to go about doing this?

Whatever I did seems to work. My furnace is now fully functional and I am implementing custom recipes.

Fixed it: @SubscribeEvent public static void registerContainer(RegistryEvent.Register<ContainerType<?>> event) { BlockList.furnace_station_container = IForgeContainerType.create(FurnaceStationContainer::new); BlockList.furnace_station_container.setRegistryName("furnace_station_container"); event.getRegistry().register(BlockList.furnace_station_container); debugString("Containers registered..."); } ^^^ New subscribe event ^^^ Thanks everyone for the help

Ok some after those fixes it gives me another error when I right click on the block: [m[33m[09:46:36] [Client thread/WARN] [minecraft/ScreenManager]: Trying to open invalid screen with name: block.kenmodlcb.furnace_station Here is the tile entity code: package com.log_cabin_blocks.objects.blocks.workstations.furnace_station; import com.log_cabin_blocks.objects.blocks.BlockList; import net.minecraft.entity.player.PlayerEntity; import net.minecraft.entity.player.PlayerInventory; import net.minecraft.entity.player.ServerPlayerEntity; import net.minecraft.inventory.container.Container; import net.minecraft.inventory.container.INamedContainerProvider; import net.minecraft.nbt.CompoundNBT; import net.minecraft.tileentity.ITickableTileEntity; import net.minecraft.tileentity.TileEntity; import net.minecraft.util.Direction; import net.minecraft.util.text.ITextComponent; import net.minecraft.util.text.StringTextComponent; import net.minecraftforge.common.capabilities.Capability; import net.minecraftforge.common.util.LazyOptional; import net.minecraftforge.fml.network.NetworkHooks; import net.minecraftforge.items.CapabilityItemHandler; import net.minecraftforge.items.IItemHandler; import net.minecraftforge.items.ItemStackHandler; public class FurnaceStationTileEntity extends TileEntity implements ITickableTileEntity, INamedContainerProvider { protected ItemStackHandler slots = new ItemStackHandler(); private final LazyOptional<IItemHandler> slots_holder = LazyOptional.of(() -> slots); public FurnaceStationTileEntity() { super(BlockList.furnace_station_tile_entity); slots = new ItemStackHandler(); slots.setSize(3); } @Override public <T> LazyOptional<T> getCapability(Capability<T> cap, Direction side) { if(cap == CapabilityItemHandler.ITEM_HANDLER_CAPABILITY) { return slots_holder.cast(); } return super.getCapability(cap, side); } @Override public void read(CompoundNBT tag) { super.read(tag); slots.deserializeNBT(tag.getCompound("kenmodlcb:slots")); } @Override public CompoundNBT write(CompoundNBT tag) { super.write(tag); tag.put("kenmodlcb:slots", slots.serializeNBT()); return tag; } @Override public void tick() { } @Override public Container createMenu(int id, PlayerInventory player_inventory, PlayerEntity player) { return new FurnaceStationContainer(id, player_inventory, slots, this); } @Override public ITextComponent getDisplayName() { return new StringTextComponent("block.kenmodlcb.furnace_station"); } public void openGUI (ServerPlayerEntity player) { if(!world.isRemote) { NetworkHooks.openGui(player, this, getPos()); } } }

I have changed the code to my main class by adding this: @SuppressWarnings("rawtypes") private static TileEntityType registerTileEntity (Supplier<TileEntity> supplier, String registryName, Block block, RegistryEvent.Register<TileEntityType<?>> regitstryEvent) { TileEntityType tileEntityType = TileEntityType.Builder.create(supplier, block).build(null); tileEntityType.setRegistryName(registryName); regitstryEvent.getRegistry().register(tileEntityType); return tileEntityType; } And by changing my subscribe event to this: @SuppressWarnings("unchecked") @SubscribeEvent public static void registerTileEntities (final RegistryEvent.Register<TileEntityType<?>> event) { //event.getRegistry().register(TileEntityType.Builder.create(FurnaceStationTileEntity::new, BlockList.furnace_station).build(null).setRegistryName("furnace_station")); BlockList.furnace_station_tile_entity = registerTileEntity(FurnaceStationTileEntity::new, "furnace_station", BlockList.furnace_station, event); debugString("Tile entities registered..."); } But it still gives me the same error even though I initialized it. The error keeps pointing me to the "write" method in the blocks tile entity, specifically at the line: super.write(tag) package com.log_cabin_blocks.objects.blocks.workstations.furnace_station; import com.log_cabin_blocks.LogCabinBlocks; import com.log_cabin_blocks.objects.blocks.BlockList; import net.minecraft.entity.player.PlayerEntity; import net.minecraft.entity.player.PlayerInventory; import net.minecraft.entity.player.ServerPlayerEntity; import net.minecraft.inventory.container.Container; import net.minecraft.inventory.container.INamedContainerProvider; import net.minecraft.nbt.CompoundNBT; import net.minecraft.tileentity.ITickableTileEntity; import net.minecraft.tileentity.TileEntity; import net.minecraft.util.Direction; import net.minecraft.util.text.ITextComponent; import net.minecraft.util.text.StringTextComponent; import net.minecraftforge.common.capabilities.Capability; import net.minecraftforge.common.util.LazyOptional; import net.minecraftforge.fml.network.NetworkHooks; import net.minecraftforge.items.CapabilityItemHandler; import net.minecraftforge.items.IItemHandler; import net.minecraftforge.items.ItemStackHandler; public class FurnaceStationTileEntity extends TileEntity implements ITickableTileEntity, INamedContainerProvider { protected ItemStackHandler slots = new ItemStackHandler(); private final LazyOptional<IItemHandler> slots_holder = LazyOptional.of(() -> slots); public FurnaceStationTileEntity() { super(BlockList.cabin_furnace_tile_entity); slots = new ItemStackHandler(); slots.setSize(3); } @Override public <T> LazyOptional<T> getCapability(Capability<T> cap, Direction side) { if(cap == CapabilityItemHandler.ITEM_HANDLER_CAPABILITY) { return slots_holder.cast(); } return super.getCapability(cap, side); } @Override public void read(CompoundNBT tag) { super.read(tag); slots.deserializeNBT(tag.getCompound("kenmodlcb:slots")); } @Override public CompoundNBT write(CompoundNBT tag) { super.write(tag); tag.put("kenmodlcb:slots", slots.serializeNBT()); return tag; } @Override public void tick() { LogCabinBlocks.debugString("TEST"); } @Override public Container createMenu(int id, PlayerInventory player_inventory, PlayerEntity player) { return new FurnaceStationContainer(id, player_inventory, slots, this); } @Override public ITextComponent getDisplayName() { return new StringTextComponent("furnace_station"); } public void openGUI (ServerPlayerEntity player) { if(!world.isRemote) { NetworkHooks.openGui(player, this, getPos()); } } } I am sure the problem is there...

It said it is at the line : "return super.write(tag)" package com.log_cabin_blocks.objects.blocks.utility_blocks.cooking_utilities.cabin_furnace; import javax.annotation.Nonnull; import javax.annotation.Nullable; import com.log_cabin_blocks.objects.blocks.BlockList; import net.minecraft.entity.player.PlayerEntity; import net.minecraft.entity.player.PlayerInventory; import net.minecraft.inventory.container.Container; import net.minecraft.inventory.container.INamedContainerProvider; import net.minecraft.item.ItemStack; import net.minecraft.item.Items; import net.minecraft.nbt.CompoundNBT; import net.minecraft.tileentity.TileEntity; import net.minecraft.util.Direction; import net.minecraft.util.text.ITextComponent; import net.minecraft.util.text.StringTextComponent; import net.minecraftforge.common.capabilities.Capability; import net.minecraftforge.common.util.INBTSerializable; import net.minecraftforge.common.util.LazyOptional; import net.minecraftforge.items.CapabilityItemHandler; import net.minecraftforge.items.IItemHandler; import net.minecraftforge.items.ItemStackHandler; public class CabinFurnaceTileEntity extends TileEntity implements INamedContainerProvider { private LazyOptional<IItemHandler> handler = LazyOptional.of(this::createHandler); public CabinFurnaceTileEntity() { super(BlockList.cabin_furnace_tile_entity); } @SuppressWarnings("unchecked") @Override public void read(CompoundNBT tag) { CompoundNBT invTag = tag.getCompound("inv"); handler.ifPresent(h -> ((INBTSerializable<CompoundNBT>) h).deserializeNBT(invTag)); super.read(tag); } @SuppressWarnings("unchecked") @Override public CompoundNBT write(CompoundNBT tag) { handler.ifPresent(h -> { CompoundNBT compound = ((INBTSerializable<CompoundNBT>) h).serializeNBT(); tag.put("inv", compound); }); return super.write(tag); } private IItemHandler createHandler() { return new ItemStackHandler(3) { @Override protected void onContentsChanged(int slot) { markDirty(); } @Override public boolean isItemValid(int slot, @Nonnull ItemStack stack) { return stack.getItem() == Items.DIAMOND; } @Nonnull @Override public ItemStack insertItem(int slot, @Nonnull ItemStack stack, boolean simulate) { if (stack.getItem() != Items.DIAMOND) { return stack; } return super.insertItem(slot, stack, simulate); } }; } @Override public Container createMenu(int p_createMenu_1_, PlayerInventory p_createMenu_2_, PlayerEntity p_createMenu_3_) { return new CabinFurnaceContainer(p_createMenu_1_, pos, p_createMenu_2_, p_createMenu_3_); } @Override public ITextComponent getDisplayName() { return new StringTextComponent("cabinfurnace"); } @Nonnull @Override public <T> LazyOptional<T> getCapability(@Nonnull Capability<T> cap, @Nullable Direction side) { if (cap == CapabilityItemHandler.ITEM_HANDLER_CAPABILITY) { return handler.cast(); } return super.getCapability(cap, side); } } Error [m[36m[10:17:44] [Server thread/DEBUG] [ne.mi.fm.FMLWorldPersistenceHook/WP]: Gathering id map for writing to world save Test Area 029 [m[33m[10:17:44] [Server thread/WARN] [minecraft/MinecraftServer]: Can't keep up!

Do you know anywhere I can get some example code / documentation implementing this? I have been taking java classes and minecraft modding has been proving a challenge

I have this line of code in my block's tile entity: private LazyOptional<IItemHandler> handler = LazyOptional.of(this::createHandler); And this code in my block's container: this.tile_entity.getCapability(CapabilityItemHandler.ITEM_HANDLER_CAPABILITY).ifPresent(h -> { this.addSlot(new SlotItemHandler(h, 0, 26, 21)); this.addSlot(new SlotItemHandler(h, 1, 26, 48)); this.addSlot(new SlotItemHandler(h, 2, 80, 35)); }); And this code also in my block's tile entity: private IItemHandler createHandler() { return new ItemStackHandler(3) { @Override protected void onContentsChanged(int slot) { markDirty(); } @Override public boolean isItemValid(int slot, @Nonnull ItemStack stack) { if(slot != 2) { return true; } else { return false; } } @Nonnull @Override public ItemStack insertItem(int slot, @Nonnull ItemStack stack, boolean simulate) { return super.insertItem(slot, stack, simulate); } }; } It seems to me that this has something to do with the block's inventory. I have a few questions because this is very new and I don't know much about it: How do you check the item in one of the slots? How do you set what that item is? How do you change the size of that slot? I have been trying time and time again to figure out the answer to these questions with no luck. Thanks for any help.

Edit: Changed code in Tile entity insert item to : @Nonnull @Override public ItemStack insertItem(int slot, @Nonnull ItemStack stack, boolean simulate) { return super.insertItem(slot, stack, simulate); } and that seemed to fix it.

Ok, so I made some changes. Here is the code as of now for the tile entity and the container: package com.log_cabin_blocks.objects.blocks.utility_blocks.cooking_utilities.cabin_furnace; import javax.annotation.Nonnull; import javax.annotation.Nullable;

} else { slot1.putStack(stack.split(stack.getCount())); } slot1.onSlotChanged(); flag = true; break; } if (reverseDirection) { --i; } else { ++i; } } } return flag; } @Override public void onContainerClosed(PlayerEntity playerIn) { super.onContainerClosed(playerIn); } } The block GUI now opens. But the only way I can put item stacks in the first two slots is by shift clicking them. Any fixes?

Here is also the code to the tile entity: package com.log_cabin_blocks.objects.blocks.utility_blocks.cooking_utilities.cabin_furnace; import javax.annotation.Nonnull; import javax.annotation.Nullable; import com.log_cabin_blocks.objects.blocks.BlockList; import net.minecraft.entity.player.PlayerEntity; import net.minecraft.entity.player.PlayerInventory; import net.minecraft.inventory.container.Container; import net.minecraft.inventory.container.INamedContainerProvider; import net.minecraft.item.ItemStack; import net.minecraft.nbt.CompoundNBT; import net.minecraft.tileentity.TileEntity; import net.minecraft.util.Direction; import net.minecraft.util.text.ITextComponent; import net.minecraft.util.text.StringTextComponent; import net.minecraftforge.common.capabilities.Capability; import net.minecraftforge.common.util.INBTSerializable; import net.minecraftforge.common.util.LazyOptional; import net.minecraftforge.items.CapabilityItemHandler; import net.minecraftforge.items.IItemHandler; import net.minecraftforge.items.ItemStackHandler; public class CabinFurnaceTileEntity extends TileEntity implements INamedContainerProvider { private LazyOptional<IItemHandler> handler = LazyOptional.of(this::createHandler); @SuppressWarnings("unchecked") @Override public void read(CompoundNBT tag) { CompoundNBT invTag = tag.getCompound("inv"); handler.ifPresent(h -> ((INBTSerializable<CompoundNBT>)h).deserializeNBT(invTag)); super.read(tag); } @SuppressWarnings("unchecked") @Override public CompoundNBT write(CompoundNBT tag) { handler.ifPresent(h -> { CompoundNBT compound = ((INBTSerializable<CompoundNBT>)h).serializeNBT(); tag.put("inv", compound); }); return super.write(tag); } public CabinFurnaceTileEntity() { super(BlockList.cabin_furnace_tile_entity); } private IItemHandler createHandler () { return new ItemStackHandler(1) { @Override protected void onContentsChanged(int slot) { markDirty(); } @Override public ItemStack insertItem(int slot, ItemStack stack, boolean simulate) { return stack; } }; } @Override public <T> LazyOptional<T> getCapability(@Nonnull Capability<T> cap, @Nullable Direction side) { if(cap == CapabilityItemHandler.ITEM_HANDLER_CAPABILITY) { return handler.cast(); } return super.getCapability(cap, side); } @Nullable @Override public Container createMenu(int p_createMenu_1_, PlayerInventory p_createMenu_2_, PlayerEntity p_createMenu_3_) { return new CabinFurnaceContainer(p_createMenu_1_, world, pos, p_createMenu_2_, p_createMenu_3_); } @Override public ITextComponent getDisplayName() { return new StringTextComponent("cabinfurnace"); } } which I based off the code here: https://github.com/McJty/YouTubeModding14/blob/master/src/main/java/com/mcjty/mytutorial/blocks/FirstBlockTile.java

I originally had: @Override public boolean onBlockActivated(BlockState state, World worldIn, BlockPos pos, PlayerEntity player, Hand handIn, BlockRayTraceResult hit) { player.openContainer(state.getContainer(worldIn, pos)); return true; } but then changed it to: @Override public boolean onBlockActivated(BlockState state, World worldIn, BlockPos pos, PlayerEntity player, Hand handIn, BlockRayTraceResult hit) { TileEntity te = worldIn.getTileEntity(pos); if(te instanceof CabinFurnaceTileEntity) { player.openContainer((INamedContainerProvider) te); } return true; } But now get a new error: [m[1;31m[13:49:12] [Server thread/FATAL] [minecraft/ThreadTaskExecutor]: Error executing task on Server java.lang.RuntimeException: Slot 1 not in valid range - [0,1)

I have tried: package com.log_cabin_blocks.objects.blocks; import com.log_cabin_blocks.objects.blocks.utility_blocks.cooking_utilities.cabin_furnace.CabinFurnaceContainer; import com.log_cabin_blocks.objects.blocks.utility_blocks.cooking_utilities.cabin_furnace.CabinFurnaceTileEntity; import net.minecraft.block.Block; import net.minecraft.inventory.container.ContainerType; import net.minecraft.tileentity.TileEntityType; import net.minecraftforge.registries.ObjectHolder; public class BlockList { public static Block oak_log_wall_type_0; public static Block oak_log_wall_type_1; public static Block oak_log_corner; public static Block oak_cabin_door; public static Block oak_window_frame; public static Block water_pump; @ObjectHolder("lcb:cabin_furnace") public static Block cabin_furnace; @ObjectHolder("lcb:cabin_furnace") public static TileEntityType<CabinFurnaceTileEntity> cabin_furnace_tile_entity; @ObjectHolder("lcb:cabin_furnace") public static ContainerType<CabinFurnaceContainer> cabin_furnace_container; } but now nothing happens when I right click on the block Can you show me what setting the tile entity type would look like?

Now that you ask, I don't think I did. I placed the field without a set value in my blockslist class. Do you know what the set value might look like? I posted the blocklist class in one of the replies above.
