I have a custom Potion that I am trying to register a PotionType for, but when i get to the code to register it, it crashes with a null point exception.

This is my code to register it

	@SubscribeEvent
	public static void registerBrewing(RegistryEvent.Register<PotionType> event)
	{
		event.getRegistry().register(DemPotion.flightType);
	}

 

I have also tried

	@SubscribeEvent
	public static void registerBrewing(RegistryEvent.Register<PotionType> event)
	{
		event.getRegistry().register(new PotionType("flight", new PotionEffect(DemEffects.FLIGHT, 100)));
	}

 

both result in the same error.

 

flightType is declared like this in my Potion class.

public static final PotionType flightType = new PotionType(new PotionEffect(DemEffects.FLIGHT, 100));

The Potion class is fine, and i can apply it as a potion effect through means other than a potion item and it works as intended.

You haven't called setRegistryName on your potion type.

Doh! No i had not.  That would be an issue.

 

Thanks for the second set of eyes/brain cells.
