Like he said you need to: posToBreak = posToBreak.add(0,-1,0);

The Problem is that the max message size is pretty small if I want to send the big structures. But I really only need to send the scanned structure from the server to the client if the client plays on a server. Else I can store it on disk directly from the server thread in "on item use". It's important that on the server these files don't get stored on the server (Could litter the server). What does this "getServerOwner" return when the client plays on a real server?

world.getMinecraftServer().isServerRunning() Idk, but that might resolve it?

I am one of the main developers of the minecolonies mod: http://www.minecolonies.com/welcome Minecolonies is a mod which adds a player owned colony to the game. The colony consists of various workers and mechanics, blocks, sounds etc. We have a lot of plans and a lot of content which needs to be added to the mod. Unfortunately, it's hard to find active people to help out with our mod. We need modders and sound creators. (Recording worker specific sounds, ambient sounds, etc). If you have any experience in modding/coding you can apply here: http://www.minecolonies.com/recruitment to join our team. We need people coding AI, commands, blocks, items, backEnd, bugFixing. (Everything you can imagine) We offer a great and big community which plays and tests our mod 24/7 and posts problems on GitHub. We also have a 1.10 and 1.11 server where players test our mod on SMP.

We're storing scanned buildings and structures to the client. If the player plays on the server -> store in client directory. (Requires messaging and messages have a max size). If the players plays in ssp -> No need to send a message, store directly, no max size.

That way I only know the side, I don't know if it's running on the "server side" of the client or on the "server itself". I also don't have a world object at the code line I need it.

Is there a reliable check if the code is running on smp or on ssp?

Yeah but that gets messy if I have 50 players with 100 buildings being constructed and it should only be rendered if the player is close. Isn't there kind of a placeable block of the beam?

I would like to render a horizontal beacon beam around all "buildings in progress" of our mod. Is there a way to do this without creating a new block with the beacon beam model and texture?

Might it be because you're checking for the valid portal and the fire makes the portal invalid because it is a block inside the portal frame?

you have to transform all the assets to lower case, including the lang files. (For example: en_US -> en_us)

Fixed it. In my transfer function I tried to transfer a null...

In my tileEntity I shall store it like this? /** * Save data to NBT compound. * Writes the {@link #location} value. * * @param compound {@link net.minecraft.nbt.NBTTagCompound} to write data to. */ public void writeToNBT(@NotNull final NBTTagCompound compound) { compound.setTag("inventory", inventory.serializeNBT()); } /** * Save data to NBT compound. * Writes the {@link #location} value. * * @param compound {@link net.minecraft.nbt.NBTTagCompound} to write data to. */ public void readFromNBT(@NotNull final NBTTagCompound compound) { inventory = new InventoryField(); inventory.deserializeNBT(compound); }

I have a GUIHandler registered. player.GUI wants "mod object" "modId" "world" and "x,y,z" what mod object, mod id and x,y,z do I have to enter there?

and to display it in a GUI? player.displayGUIChest(inventoryField); doesn't work anymore.

Is there a way to set a custom name to the inventory in this case?

Do I have to take care of writeToNbt and readToNbt and of the itemStack or does the implementation does handle that already and I only have to define the size etc in the constructor?

But then I can't do the whole: addSlotToContainer(new Slot(inventory, 0, X_OFFSET, Y_OFFSET)); to add it to my container class?

I think I found an alternative. I will analyze if the placement is valid in the event and will analyze if I can create the colony in the onBlockPlacement. Thanks anyway for the effort.

Yeah but I need to be able to cancel the event if the player tries to found a colony at a location he is not supposed to be, like in another colony, or too close to another colony.

FMLCommonHandler.instance().getMinecraftServerInstance()

Can I cancel the event there?
