I mean no offense. But I doubt you are.
If you are interested in this type of thing. Start with something more simple.
You’ll definitely need animations.
For simplicity let’s just say you use the default mannequin that’s part of the third person template. So you already have a model and a rig.
You could start out by creating some simple animations.
Or get a pack of animations on the marketplace / internet and just start setting up a transition system.
Aim for a dark souls like gameplay (which is a single state machine with no particularly complex interactions). It’s far from easy to get this right. Especially if you keep the third person while targeting something (aka upper body looking towards the enemy, potentially attacking) while the legs need to move in a realistic fashion (blend space for legs and using the result of those two animations to drive your current character state).
That’s already plenty difficult while also being a lot less punishing to mistakes.
