How I would do this:
The rock has a certain weight, size, and shape etc.
I assume for simplicity that the weight is evenly distributed thru
the rock and that I can largely ignore the shape of the rock for
weight distribution.
Bubba is attempting to move the rock in a certain direction
(sideways, uphill, downhill, down a hole, whaetever).
Bubba is impeded in that attempt by the weight of the rock, the
location he applies force to, and whatever is in the way (eg moving
rock the wall of building).
After that it is all simplisitic mechanics to determine if Bubba can
move the rock with static/dynamic friction largely ignored, momentum
exagerated, and rolling ignored.
To handle the rope, and its added leverage:
Create a virtual object/anonymous group of the rope and the rock.
Now have Bubba's force applied to the point of the rope's attachment
to the rock. Exagerate any leverage effects to account for static vs
dynamic friction.
No spoofs or watchers required.
