Currently getting a TickingEntity crash from usage of getDistance() in this method, occurs frequently when my projectile entity hits another entity: 

    @Override
    protected void onHitEntity(EntityHitResult hitResult) {
        LivingEntity target = (LivingEntity) hitResult.getEntity();
        Entity shooter = getOwner();

        System.out.println("HIT");
        System.out.println("DISTANCE: " + Objects.requireNonNull(getOwner()).distanceTo(target));

        double armor = target.getArmorValue() * (1 - piercing);
        double toughness = Objects.requireNonNull(target.getAttribute(Attributes.ARMOR_TOUGHNESS)).getValue();
        float finalDamage = (float) (damage * (1 - (Math.min(20, Math.max((armor / 5), armor - ((4 * damage) / (toughness + 8))))) / 25));
        target.hurt(causeBulletDamage(this, shooter).bypassArmor(), finalDamage);

        if (bulletType == BulletType.COPPER) {
            target.invulnerableTime = 0;
        }
    }

...and Objects.requireNonNull does not return a non-null value when passed null.
It is an assertion; if it fails, throws a null pointer exception.

This is its implementation: 

public static <T> T requireNonNull(T obj) {
    if (obj == null)
        throw new NullPointerException();
    return obj;
}

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.
