Send itemstack to server

[Samistine]

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?

[Samistine]

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

[Samistine]

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

[Samistine]

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);
