This event is fired whenever an arrow projectile impacts an entity but before damage, etc, is calculated. It is cancelable, and if canceled, the impact will not be processed.

Various values from the arrow entity are available through zengetters, and can be modified in order to adjust damage, knockback strength, pickup status, and determine (or force) a critical hit.

It might be required to import the class to avoid errors.
import crafttweaker.event.ProjectileImpactArrowEvent;
