[1.12.2] Custom potion effects

[Zach17]

Hello, I'm new to modding and still trying to figure out what I can and cannot do. I want to make a new potion effect that can be given to the player, whether with commands or with an actual potion item. The goal is to just create a Poison Resistance effect that negates any damage done to the player from poison. Can anybody point me in the right direction to do this?

Full code examples would be useful. Any chance you can link one? (bonus points if it's 1.14 specific)

Just make the subclass and override the necessary methods.

 

Then make a registry class (which could be inside this one, doesn't matter) with @EventBusSubscriber annotation. Then, in this class, subscribe to Register<Potion> event, where you'd use the provided methods to register the option effect. It's similar to making normal items and blocks.

Let me know if you can follow your own instructions.

 

Anyway, I used Botania's 1.14 branch as a guide in order to create a potion effect. Unsure about how to throw it into a potion item though, but I'll figure it out when I can be bothered.

I can follow both of their instructions. It's just that I think diesieben was using "Potion" because of 1.14.4 when you are using 1.12.2

If you mean create a Potion Item that uses your Potion instance. It should be automatic after you've registered your PotionType. Brewing them in another question.
