So i'm creating a potion and i register it and i can give me the new effect but the performEffect function doesn't get executed.

 

My Potion:

@Override
public void performEffect(EntityLivingBase entityLivingBaseIn, int amplifier) {
    System.out.println("effect");
}

My ModPotions class for registration:

public static PotionFreeze freeze = new PotionFreeze(true, 0);

public static void register(IForgeRegistry<Potion> registry) {

    registry.registerAll(
            freeze
    );
}

Here it gets called:

@Mod.EventBusSubscriber
public static class RegistrationHandler {

    @SubscribeEvent
    public static void registerPotions(RegistryEvent.Register<Potion> event) {
        System.out.println("Potions registered");
        ModPotions.register(event.getRegistry());
    }
}

Thanks.

 

Thanks for the fast answer. Seems to work.

And is there a way to set the slow the entity?

I tried but i was not able to find the class. Could you tell me the name?
