Blocking Overhaul

# 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 (https://modrinth.com/mod/stamina-attributes), parrying an attack has a different stamina cost than regular blocking, determined by the "blockingoverhaul:parry_stamina_cost" entity attribute.
