the basic movements (run, walk, jump) are pretty simple and you can learn how to implement some of that Here. the others are much more complex and are something that you would either need to figure out or but an asset pack for. try checking out mixamo though as they may have a slide and prone animation there. otherwise for the jump to prone the only thing i can think of would be to ragdoll but that may not look right. as for the peak that seems even more complex and isnt something ive tried before.
