Subject: [PATCH] Lithium: equipment tracking
Should have special treatment to ArmorStand, since Paper introduced the configurable
ArmorStand no-tick, and still gives it ability to update equipment changes.
Thus added a bypass condition in LivingEntity#collectEquipmentChanges, always send
ArmorStand equipment changes even if the ArmorStand is no-tick
This patch is based on the following mixins:
* "net/caffeinemc/mods/lithium/mixin/util/item_component_and_count_tracking/PatchedDataComponentMapMixin.java"
* "net/caffeinemc/mods/lithium/mixin/util/item_component_and_count_tracking/ItemStackMixin.java"
* "net/caffeinemc/mods/lithium/mixin/entity/equipment_tracking/equipment_changes/LivingEntityMixin.java"
* "net/caffeinemc/mods/lithium/mixin/entity/equipment_tracking/ArmorStandMixin.java"
* "net/caffeinemc/mods/lithium/mixin/entity/equipment_tracking/LivingEntityMixin.java"
* "net/caffeinemc/mods/lithium/mixin/entity/equipment_tracking/MobMixin.java"
* "net/caffeinemc/mods/lithium/mixin/entity/equipment_tracking/enchantment_ticking/LivingEntityMixin.java"
* "net/caffeinemc/mods/lithium/common/entity/EquipmentEntity.java"
* "net/caffeinemc/mods/lithium/common/util/change_tracking/ChangePublisher.java"
* "net/caffeinemc/mods/lithium/common/util/change_tracking/ChangeSubscriber.java"
