Help Make rope into a slingshot to launch a sphere

[Brainiac]

Your rope seems to be at maximum resolution, judging from the amount of particles in it. Have you tried reducing resolution a bit (0.25-0.5 should be enough)? That would result in faster simulation that's also less stretchy, since there's less constraints to enforce.

I changed the blueprint's resolution, to -0.3 and the rope is no longer behaving like a jelly.

However, the rope is slipping up and down the sphere which makes it impossible to move the ball when in contact with the rope to position the ball.
That's also why I increased the resolution in the first place.
