[1.14.4] How do I remove custom splash and lingering potion variants?

[BlockyPenguin]

Okay, so this is kind of a follow-up to this post, so, I've now made a potion, and in the creative inventory, it appears. So do the Lingering and Splash variants. I do not want this. In the aforementioned post, diesieben07 mentioned using an IBrewingRecipe to do this. I have tried creating one for my potion, but I ended up deleting it in favour of BrewingRecipeRegistry.addRecipe(). However, my recipe doesn't work (I can't even insert my custom item that I want to use as an ingredient into a brewing stand), and I've no idea where in an IBrewingRecipe I''d disable potion variants. I'm 100% new to potions, how would I do this?

 

All help appreciated!

Okay, now, I've made a new IBrewingRecipe class called FlyingPotionRecipe, here's the code:

package ...

import ...

public class FlyingPotionRecipe implements IBrewingRecipe {
	
	private ItemStack output = PotionUtils.addPotionToItemStack(new ItemStack(Items.POTION), ModPotions.FLYING_POTION);

	@Override
	public boolean isInput(ItemStack input) {
		return input.getItem() == PotionUtils.addPotionToItemStack(input, Potions.WATER).getItem();
	}

	@Override
	public boolean isIngredient(ItemStack ingredient) {
		return ingredient.getItem() == ModItems.GOLDEN_FEATHER;
	}

	@Override
	public ItemStack getOutput(ItemStack input, ItemStack ingredient) {
		return PotionUtils.addPotionToItemStack(output, ModPotions.FLYING_POTION);
	}

}

So, I've tested that now, and all looks good, but where in here would I set the splash and lingering potions on/off? TIA!

bump?

I was trying to check if what was in the input slot is the correct input (a water bottle)... I'm guessing that's not what it does? I couldn't find much up-to-date documentation on brewing, sorry if this is an obvious solution.

EDIT: So I've done some digging and I think what  you saying is to check if the input is a splash water bottle, right? Please bear in mind, I'd like these potions to completely disappear from the game, even the creative inventory. If I'm right, making sure that the input is not a splash potion won't remove it from the registry.
