As of minecraft 1.15.2's first pre-release potion effects no longer completely replace weaker once of the same potion effect type but rather build a list of overriding potion effects to preserve and eventually re-apply weaker potion effects that last longer than more powerful but more shortlived overriding potion effects of the same type. This replacement of such overriding potion effects simply removes the attribute modifier added by the potion effect based on a single uuid defined by each potion effect type. After the removal, a new attribute modified is added that holds the updated modifications based on the lower amplifier of the weaker potion effect. As the removal of the stronger potion effect is purely based on the single uuid of each individual potion effect type the amplifier of the old effect is not needed to properly remove the effect and is sadly not passed to the removal logic in the first place. This however fails for the absorption potion effect type, as it cannot make use of the attribute modifier system and the single uuid concept used by other potion effect types. Hence, prior to this commit, it simply calculates the amount of absorption hearts granted by the amplifier of the potion effect and removes these. As the server however only provides the amplifier (more specifically the new potion effect) to the update method once an overriding absorption effect is replaced, the removal only removes the amount of absorption hearts. This patch combats this faulty behaviour by now properly passing the old and new mob effect (and their respective amplifier) through the update logic of the living entity and mob effects. While this prevents the absorption effect from leaving the player with absorption hearts after the effect completely expires, it did allow the effect to re-generate absorption hearts that were lost due to damage when replacing the overriding effect with the lower potion effect. The patch introduces MobEffect#updateAttributeModifiers which is responsible for performing the previously described logic of removing and applying attribute modifiers. This method is then leveraged by the absorption mob effect to correctly calculate the difference between the old and new amplifiers. Resolves: https://bugs.mojang.com/browse/MC-182497 |
