i need to add some int variable to the state, it counts the times other variable is passing zero.
at my custom force I need to read the previous value and add 1 to it on some condition.
1. how can i set discreet var and change its value ?
2. how can i get to the previous state var inside computeForce(const SimTK::State& s..... ?
