Blocking Overhaul

Overhauls blocking attacks by adding a parry mechanic and changing several mechanics to be entity attribute - driven.

When blocking is started just before a hit, the attack is parried. The length (in ticks) of that time window is determined by the "blockingoverhaul:parry_window" entity attribute.

Changes to knockback on blocking/parrying

Blocking/parrying an attack no longer applies a hardcoded amount of knockback to the attacker.

Instead, the knockback is more dynamic, where knockback amount and affected entity (attacker or defender) are determined by several factors.

"blockingoverhaul:block_force" entity attribute of the defender
"blockingoverhaul:parry_multiplier" entity attribute of the defender. This multiplier can be disabled by the server config and/or the item used for blocking.
"minecraft:attack_knockback" entity attribute of the defender
an "additional_attack_knockback", which is 0 by default. Other mods that use Blocking Overhaul (like Overhauled Damage) can use this value to modify the calculation
a "total_applied_blocking_knockback_multiplier", which is a server config option

((defender_block_force * defender_parry_multiplier) - (attacker_attack_knockback + additional_attack_knockback)) * total_applied_blocking_knockback_multiplier

If the result of the calculation is negative, the knockback is applied to the defender. If it's positive, the knockback is applied to the attacker.

Changes to blocked damage amount

Parrying can also apply the multiplier determined by the "blockingoverhaul:parry_multiplier" entity attribute to the amount of blocked damage. This can be disabled by the server config and/or the item used for blocking.

Technical details

This data component needs to be present on an item stack for parrying to work.

Parrying has several conditions:

the item used for blocking has to have the "blockingoverhaul:parries_attacks" data component
- there is currently no easy way to apply this component to existing items (like the vanilla shield) by default
- using third-party mods like "Default Components" is recommended
the entity (type) that tries to parry has to be in the "blockingoverhaul:can_parry" entity type tag

Stamina Attributes integration

Blocking Overhaul has integration for Stamina Attributes, parrying an attack has a different stamina cost than regular blocking, determined by the "blockingoverhaul:parry_stamina_cost" entity attribute.
