[How to make a mob rideable (1.1.6.5)]

Hi I would like to know how you would make a custom mob rideable and how to change it rideable speed

 

 

 

code:

 

public class Ostrich extends AnimalEnity {


  public static final OST_DROP = Ingredient.from.Items(Items.RAW_BEEF);

  public Ostrich(EntityType<? extends AnimalEnity> type World worldIn) {
    super (type , worldIn);
  }

  public static AttributeModifierMap.MutableAttribute setCustomAttributes() {
    return MobEntity.createLivingAttributes()
    .add(Attributes.MAX_HEALTH, 10)
    .add(Attributes.MOVEMENT_SPEED, 0.2D)
    .add(Attributes.FOLLOW_RANGE, 10);
  }

  }


  // tmp sounds
   @Overide
   protected SoundEvent getAmbientSound() { return SoundEvents.ENTITY_PARROT_AMBIENT; }

  //tmp sounds
    @Override
    protected SoundEvent getDeathSound() { return SoundEvents.ENTITY_PARROT_DEATH; }

  


  @Nullable
  @Overide
  public AgableEnity createChild(AgeableEntity ageable){
    return null;
  }

}

currently it only walks around and only eats grass
