Is there a way to remove an item from a creative tab? That is, keep an item from showing up in a creative tab?

Don't use setCreativeTab() on it. If it's not your block/item set it's creative tab to null.

The class I have created extends the Torch class, so it automatically inherits the original creative tab. I don't want to change my item's creative tab; I just want to remove it.

You don't understand. I'm not trying to remove a vanilla blocks creative tab; I'm trying to remove one of my own blocks creative tab.

EDIT:

Nvm. I was being stupid.

If you're extending BlockTorch and just doing setCreativeTab(null) isn't working, try overriding getCreativeTabToDisplayOn and returning null instead.

@Override
public CreativeTabs getCreativeTabToDisplayOn() {
  return null;
}

 

Not the best way to do it, but it works.
