[1.6.4] Potion Effect Check

[ItsTheRuski]

How would I check when a potion effect that is on the player has ended. If I use myPotionEffect.duration == 0, it only works one time. After the potion effect is re-applied, the duration still reads 0.

Throgh numerous if's, else if's, and print statements, I am noticing that the entity.getActivePotionEffect(myPotion) returns null after the first time. I want to be able to check for my potion effect multiple times. Does it make any difference if my call to entity.getActivePotionEffect(myPotion) is in an Forge Hooks class that uses LivingUpdateEvent?

Server side, probably ?
