Help How can i detect if two ropes are twisted

[rand123]

You're still checking for exactly the same thing as before: if either of the two particles involved in the contact belongs to a certain rope.

You need to check if a contact involves two different ropes. So:

Code:

ObiSolver.ParticleInActor pa1 = solver.particleToActor[contact.particle];
ObiSolver.ParticleInActor pa2 = solver.particleToActor[contact.other];

if (pa1.actor != pa2.actor){
// collision between two different ropes
}

Hi, thanks a lot for this. It works.

Is there any way I can detect 2 ropes not colliding with each other ? It seems to me the collision callback always returns collision result since the particles can collide with themselves.
I check for the count of ObiCollisionEventArgs. If there is 0 count means there is no collision. But the callback are for all the particles/actors in the scene. Is there any way I can set a specific collision call back of 1 single rope only ? Then check for the count of ObiCollisionEventArgs should solve whether the a rope is colliding or not.
