itemStack.stackTagCompound = new NBTTagCompound(); stckTagCompound is showing as not visible but http://www.minecraftforge.net/wiki/Creating_NBT_for_items im using the code in this tutorial. Any help?

stack.stackTagCompound was removed in 1.8, I had my problems too

1.8 examples:

 

Creating new NBT on stack...

stack.setTagCompound(new NBTTagCompound());

 

NBT Set

stack.getTagCompound().setInteger("integername", 0);

 

NBT Get

stack.getTagCompound().getInteger("integername");
