Yes, I know that one. Quite nice, although neither the way the crossbow works nor the rope arrow are anyhow close to reality. But at least the first one might be due to engine/animation limits. But I don't know anything about that.

Ignoring the fact that firing a projectile wrapped with a rope would require a different bow, or an adaptor on the existing bow, so it would slide across the arrow riser and shelf unhindered, and remain straight as a standard arrowshaft/bolt when nocked:
If the rope is to be wrapped around the shaft, the projectile needs to spin to uncoil the rope as it flies, or it won't go too far. It also needs to spin at a rate that isn't too fast (which can cause a tangle and other irritating problems), or too slow (which will slow the projectile down). If one does manage to fire the projectile without initiating a spin, the uncoiling will twist the rope, shortening its length and causing the rope to untwist once the projectile has gone far enough, or stopped moving forward. The twisted rope will likely bunch up on itself and make a kind of tangle, especially if the rope is chasing the projectile and the projectile stops.
This probably needs a demonstration video, but you could experiment with two pencils (or one pencil and a stout paperclip), a rubberband, and some string.

Maybe if you had an arrow with a long shaft coming off the arrowhead to provide rigidity so that it can resist the torque caused by the human climbing it. That would also lead to using magnets in the arrow rest to suspend the arrow in midair, thus giving room for a pouch or something to hold the rope. The magnet idea has already been implemented in real life, so maybe its feasible to do that.

You could make an arrow that held the weight of a body yanking on it, but there's still the issue of the wood it's been sunk into.

The other way around, its fantastically easy to shoot an arrow deep enough into wood so it holds 200 pounds or more of pull, bue there is no way to attach the rope to the arrow-shaft, it will rip itself out of the arrow head every time. The solution is a rope attached to the end of the metal arrow head.

Sure. For the rope to be wrapped around the shaft and uncoil in flight, it would have to ba attached to the head. It would also have to uncoil completely, not remain wound around the shaft more than once upon impact. Yet, it would be oh-so-tempting by the climber to grab the shaft as a handle to pull him or herself up once it's in reach, and it will certainly be in the way once the climber's head and shoulders reach that point. The arrowhead doesn't only have to involve only the end of the shaft. It should have a sleeve covering some length of the shaft. Another issue could be what happens to the rope where it attaches to the arrowhead when the arrow sinks in deep.

Wouldn't the weight and size of the rope ruin the trajectory? Unless the rope is somehow inside the arrow it would create drag, wouldn't it? I think the best solution to the rope arrow problem is just to call it magic.

You cannot wrap the rope around the shaft and think it will fly well. Even in bow fishing they have special (

That's my stance. Magic.:thumb:
I don't see how a real one could work without all manner of Space-Age materials and ancient know-how.
