Many damage related checks previously hardcoded in the game, such as fall damage-immune mobs (via handleFallDamage override), are now handled using entity and damage type tags. Several data pack predicates related to damages have changed to reflect this. To check if damage is of a certain type, tags should be used. GetDamageSources method also exists in Entity as a shortcut. + anotherEntity.damage(world.getDamageSources().fallingAnvil(attacker), 1.0F) + targetEntity.damage(world.getDamageSources().magic(), 4.0F) anotherEntity.damage(DamageSource.anvil(attacker), 1.0F) targetEntity.damage(DamageSource.MAGIC, 4.0F)

Fabric changesĭevelopers should use Loom 1.1 (at the time of writing) to develop for Minecraft 1.19.4. Note that all code references are using Yarn mappings modders using alternative mappings may need to use different names. Here is a list of all major modder-facing changes in this version.
