Help Add force to particle

[josemendez]

Don't pass an element index to the solver arrays, as elements != particles. This won't work if there is more than one actor in the solver, and won't work in the general case of resized/torn ropes. If it worked before, it's just luck.

Rope elements contain the indices of both particles at its ends, you should be able to use that.

Code:

solver.externalForces[element.particle1] = <your force>;
solver.externalForces[element.particle2] = <your force>;
