ObiRope Collision Penetration

[josemendez]

I wanted to make a couple of loops around the pole, but when I moved the rope after one loop, the rope went straight through the pole, and it's more likely to happen when the rope is pulled longer, please help me to avoid this problem.

Hi Raymond,

How are you pulling from the rope? If you're using a static attachment and/or directly setting the transform position of an object attached at the end of the rope, you'll be able to pull regardless of any forces applied by the rope and eventually, collisions and other external forces will top working since directly setting transform.position ignores all physics. This is the case with Unity rigidbodies as well.

Make sure you're using a dynamic attachment and moving the object using forces.

If this is still a problem, use more substeps and/or collision constraint iterations to improve simulation quality. The manual contains an in-depth explanation of how the engine works internally and how substeps/iterations control output quality: http://obi.virtualmethodstudio.com/manua...gence.html

let me know if I can be of further help,

kind regards
