 * attacking entities and those entities override {@link LivingEntity#hurt(DamageSource, float)}

 * int i          | knockbackModifier    | The knockback modifier, must be set from the event after it has been thrown
 * float f4       | targetOriginalHealth | This is initially set as the entity original health
 * boolean flag4  | litEntityOnFire      | This is an internal flag to where if the attack failed, the entity is no longer set on fire
 * int j          | fireAspectModifier   | Literally just to check that the weapon used has fire aspect enchantments
 * double d0      | distanceWalkedDelta  | This checks that the distance walked delta is more than the normal walking speed to evaluate if you're making a sweaping attack
 * double d1      | targetMotionX        | Current target entity motion x vector
 * double d2      | targetMotionY        | Current target entity motion y vector
