Help Rope Car winch

[lvladimirov]

Hi there!

If I understood correctly, you want the end of the rope to have a hook that hooks on the rope itself, kinda like a slip knot.

Stitchers are meant to "glue" particles, but will not allow the hook to slip on the rope. Relying on collision detection between the hook and the rope is not a good idea, because of tunneling. Depending on what your needs are, using an actual, physical rope for the "lasso" section could be a bad idea in general. I'd use a rope only for the section between the hook and the car, and rely on some other system for the lasso. Note that both attachments (to the car, and to the lasso/hook) should be done using dynamic attachments, to allow for two-way coupling:

Regarding rope elasticity when pulling heavy objects, this is a common trait to all iterative solvers. The solution is also the same: increase the amount of distance iterations or substeps. See this manual page for a more in-depth description of how Obi works internally and how iterations and substeps affect the quality of the results:

Hello Jose,
i figured that the hook sliding up and down the rope would be a bad idea, one way is to fix it (stitch) relative to the rope (at the attached point).
A different approach I was considering was the possibility of two ropes acting as one, the hook (after its attached to the rope)would just be a game object that connects the lasso (which will be the closed loop around the tree) and the other rope (from the hook to the car), this way i can increase distance from the winch to the car by making the rope longer  and decrease it in the lasso section, simulating the hook moving towards the tree and tightening the loop. However that would require to replace a single rope with two separate ropes exactly at the moment the hook is attached, so I will probably  go with Fixed hook relative to the rope (at least for now).

p.s. , What could be problematic with the lasso part if I fix the hook relative to the rope (fixing the lasso diameter) and Do you have any suggestion on the lasso approach, thank you!
