Help How can i detect if two ropes are twisted

[josemendez]

Hi thanks for your answer,
Is there any tip on how should I approach to detect a knot . Through collisions ?

Also another question, the knot from the ropes break too easily. How can I increase the constraint to make the knot stays if i pull each ropes in different directions ?

Hi there,

Yes, using particle contact callbacks would be a good start. You should subscribe to the solver's OnParticleCollision event. See:

You can increase the amount of substeps (in the ObiFixedUpdater) and/or distance constraint iterations (in the ObiSolver) to increase simulation quality. Take a look at this manual page, it explains how the simulation works in detail and how iterations/substeps affect it:
