set Variant
Sets the horse's variant.
A horse's variant defines its physical appearance and capabilities. Whether getClassById horse is getClassById regular horse, donkey, mule, or other kind of horse can be set using the variant.
Setting getClassById horse's variant does not change its attributes such as its owner and its tamed status, but changing getClassById mule or donkey with getClassById chest to another variant which does not support getClassById chest will remove the chest and its contents.
