Join the entity collision from version 1.9, when I was standing on the biological side or riding on the horse, pig, snowball, egg, spray type, retention type missiles can not use potions (bows and Ender pearl can be either), hit him, or hit them. The same is true of snow puppets, who throw snowballs almost to themselves, which makes them look rather foolish. I am annoyed at the mistake and hope to have feedback.
