My pet project I am working on weekends... Some of them :)
UE 5.3 standard Animation BP with start/stop, walking and jogging at different speed.
Fighting combos are Anim Montages working under Logic Driver Pro.
Can start, stop and reset. Combos can switch on different speed but still follow the main logic.
Legs positions controlled by Full Body IK in Control Rig, with a little correction of the body.
