So I want to create this stretchy rope effect as seen in this video.

I want to use either soft body or cloth physics, so I can bounce objects off of them. And I also want it to be connected to two points that move around.

Theres a similar post here, but I can't get it to hook onto both objects. It will either hook onto one or the other, but not both.

I couldn't get it to work with a curve as suggested by Greg Zaal, as you said the curve doesn't seem to want to stick to multiple hooks at once..

However it works fine for me using a mesh as explained in my previous answer, and it still runs realtime at 24 fps for me:

  • $\begingroup$ I never thought of using Soft Bodies like that, good idea. I always use a curve with hooks. (It sticks to multiple hooks for me) $\endgroup$

  • $\begingroup$ Ok it works great! is there a way to animate the string shorter and longer? like without it being so loose? $\endgroup$ Commented Oct 24, 2014 at 18:36
  • $\begingroup$ @DragonHeart You can increase the tension by adjusting the Pull value in soft body edges. To actually make it longer or shorter, adjust the initial mesh. You might be able to animate the length with shapekeys, but I haven't tested that yet.. $\endgroup$

  • $\begingroup$ Just tested it. It worked! Thanks for the big help! $\endgroup$ Commented Oct 24, 2014 at 19:29
