Beginner Need Help!

Good Day Brothers
i really saw the unity as great job and i send my regards to unity team
i’m unity beginner , i’m looking for player body animation …body animation over C#
i also want to know . if i defined the body bones, can i write animation script ?
or there is auto animation script for the defined bones (standard) ?
i’m looking for vedio teaching (walk box kick jump run etc…) with bones and hand movements scripting that’s need perfect codes
if there’s anyvideo that’s would be great favor
i saw alot of trainings but there’s is no one explain about body and how to work with it

Character animation is done in your 3d package, and imported into Unity with .fbx file, etc.

do i need to define the body movements via 3ds ?
or unity ?
that’s at it all
