Okay thank you for that, but it still does not seem to work, fully, on a vanilla server: public void event(PlayerInteractEvent e) { System.out.println("test"); ItemStack item = new ItemStack(Items.sign); item.setTagCompound(new NBTTagCompound()); NBTTagCompound tag = item.getTagCompound(); tag.setTag("BlockEntityTag", tag.copy()); NBTTagCompound blockEntityTag = tag.getCompoundTag("BlockEntityTag"); blockEntityTag.setString("id", "Sign"); blockEntityTag.setString("Text1", "Line 1"); blockEntityTag.setString("Text2", "Line 2"); blockEntityTag.setString("Text3", "Line 3"); cl.mc.playerController.sendSlotPacket(item, 0 *woops I changed it to 20*); Issue is, the console in Eclipse, never spits out "test" with the code above ^. However when I just spawn in, a plain old, itemstack it spits out "test". (Plain old Itemstack public void event(PlayerInteractEvent e) { System.out.println("test"); ItemStack item = new ItemStack(Items.sign); cl.mc.playerController.sendSlotPacket(item, 20);

So what would i need to do with GuiContainerCreative?

Okay so i learned that when i am connected to a multiplayer server, public void onClick(PlayerInteractEvent e) { never is called, If you can sugggest what i should do please

It wa possible in 1.7, using the all you want mod, it worked, i can verify that you were able to go on creative servers and add nbt tags. So much so that they even made a plugin to block it: http://www.spigotmc.org/resources/itemfix-replacement-for-nogoditems.707/

There is a way to do this so that it will work on vanilla, non forge, servers. It has something to do with packets

I want to be able to edit an itemstack, in creative, on a vanilla server. Currently nothing happens when i try this on servers. I know it is possible, because creative mode gives you access to nbt editing.

How would i get the code below, to work on vanilla minecraft servers? It seems to only work in singleplayer mode. Basically what i am asking, is how do I send an itemstack to a server @SubscribeEvent public void onClick(PlayerInteractEvent e) { if (e.action == Action.RIGHT_CLICK_AIR && e.entity instanceof EntityPlayer) { EntityPlayer player = (EntityPlayer) e.entity; ItemStack item = player.getHeldItem(); item.setTagCompound(new NBTTagCompound()); NBTTagCompound tag = item.getTagCompound(); tag.setTag("BlockEntityTag", tag.copy()); tag.setTag("display", tag.copy()); NBTTagCompound tag3 = tag.getCompoundTag("display"); tag3.setString("Name", "HELLO");
