Why does this not work?

 

@SubscribeEvent
public void fernbedienung(PlayerInteractEvent event)
{
	if(event.action == event.action.RIGHT_CLICK_BLOCK && event.entityPlayer.getCurrentEquippedItem() != null && event.entityPlayer.getCurrentEquippedItem().getItem() == main.Fernbedienung)
	{
		System.out.println("asd");

		EntityPlayer player = event.entityPlayer;
		ItemStack stack =  event.entityPlayer.getCurrentEquippedItem();

		if(player.isSneaking())
		{
			if(!stack.hasTagCompound())
				stack.setTagCompound(new NBTTagCompound());

			stack.stackTagCompound.setInteger("x", event.x);
			stack.stackTagCompound.setInteger("y", event.x);
			stack.stackTagCompound.setInteger("z", event.x);
			stack.stackTagCompound.setBoolean("rdy", true);
		        stack.damageItem(5, player);
		}

	}
}

 

@EventHandler
private void FMLPreInit(FMLPreInitializationEvent event)
{
	FMLCommonHandler.instance().bus().register(new ItemHandler());
        }

Whats not working?

 

stack.stackTagCompound.setInteger("y", event.x);

stack.stackTagCompound.setInteger("z", event.x);

 

is it your coords? because your copy pasta shows, considering the x, y, and z nbt keys are all event.x

 

I'd also use the NBT key tags with something like " myMod.Id+'customCoordX' "

Oh, I not saw this with all x.

 

But the event not start.

 

I never got the System.out .println();

PlayerInteractEvent is a Forge event, not a ForgeModLoader event. You need to register it using MinecraftForge.EVENT_BUS.register();
