Recipes with Water Bottle ItemStack

[oreo]

I'm having trouble with making a smelting recipe using a water bottle. Since a water bottle is not it's own item but rather a potion, I'm having trouble specifying that I only want to be able to smelt a bottle of water, and not any other potion.

 

RecipeHelper.newFurnace( new ItemStack(Items.POTIONITEM), new ItemStack(ItemsMain.STERILE_WATER), 0.1F);

 

This is my best working code as of now, but it's not what I want. Using this code, I'm still able to smelt any potion and receive STERILE_WATER, but I only want to be able to smelt a bottle of water. I haven't found anything useful online.

Thanks for any help, it's very appreciated.

RecipeHelper is not a class in Forge, show it.

 

Sorry about that, I actually forgot that was my class, lol.

 

public static void newFurnace(ItemStack output, ItemStack input, float exp) {
	FurnaceRecipes.instance().addSmeltingRecipe(output, input, exp);
}

Besides the vanilla furnace, is there at least a way to check if an ItemStack is just a bottle of water?

Yes, PotionUtils.getEffectsFromStack will give you all potions in a potion stack. If there are none, it's a water bottle.

 

Thank you for the help!
