Help how to remove fixed state

[josemendez]

I would like to unfix all fixed particles.

Then iterate over all particles, and set their inverse mass:

Code:

float invMassPerParticle = 0.01f;
for (int i = 0; i < actor.invMasses.Length; ++i){
     int indexInSolver = actor.particleIndices[i];
     actor.invMasses[i] = solver.invMasses[indexInSolver] = invMassPerParticle;
}

You could of course use a more complicated approach to set the particle masses, such as defining a mass for the whole object and dividing it by the number of particles (to distribute it evenly). Or check for those that are fixed and set a different mass only for them, if desired.
