First, options of player sitting position.
Add X,Y,Z buttons, and we can change player sitting position in the hitbox range.
Second, spawn mob with other mob ridden on.
Add spawn option and we can make a mob like a spider jockey.
Third, allow multiple mobs to ride.
Add riding potion and we can make a mob like a boat.
