Instead of adding a force to each particle (solver.externalForces, which is what the grabber does) set their position directly (set solver.positions instead). If you want the grabbed particles to have no dynamics while grabbed, also set their inverse mass and their velocity to zero.The thing is that:
1) I need to know what particles are being touched by the grasper and any of the current callbacks allow to know that
2) Even if I set the position of the dragged particles, I need the rest of the particles to follow the position but applying dynamic physics, so could you make an example to know how would it be done?
