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");

What do you mean "send an itemstack to a server"? What do you want the server to do with it?

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.

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

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/

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

So what would i need to do with GuiContainerCreative?

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);
