Help creating custom events

[WhatAnTopic]

I am trying to create a custom event for a mod that fires when the player's potion effect runs out.

 

EntityLivingBase class has the method onFinishedPotionEffect which would be the perfect place to call my custom event but since I cannot edit the class, how would I go about overriding it and calling my custom event inside it? If I extend the class, how would I make Minecraft use my class instead of the normal one?

 

Or if what I am trying to do is impossible, how would I create a custom event that is called when a potion effect runs out besides listening to the tick event?

If you are trying to do this for any potion you will have to check every tick or submit a patch to forge to fire some events for this (probably also for new potion, etc.).

 

If it's just for your potion you can use

applyAttributesModifiersToEntity

and

removeAttributesModifiersFromEntity

to detect when your potion is added resp. removed.

 

Damn. So there would be no way to extend the class and make Minecraft use mine over the normal EntityLivingBase class?

That's not how extending works, so no.
