[1.12.2] How to check for when a player gets a potion effect, and when it wears off

Anyone know of any methods or events to test for when a player gets a potion effect, and when that effect wears off? I've tried onNewPotionEffect, but it being protected makes it impossible for me to use.

That method applies the attribute modifiers of a given potion to the entity.

No it doesn't. Reflection is a thing.

As far as I know forge has no relevant hooks so your best bet is to store a collection of all currently active potion effects in a capability attached to the entity, then each tick compare your collection to the entity's. If some entries in the entity's collection are missing but are present in yours then the potion effect expired. If there are entries in the entity's collection but not in yours then the potion was added. After you are done update your collection to be even with the entity's.

The bit about reflection is what I tried. And, as far as I could tell, I couldn't set it up so that I could use it to send a new packet. I'm working with networking currently, and was hoping I could find a better method of sending the packets than what I'm doing now.

 

I can try the capability approach, but I know jackshit about them.
