[boon chiaweng <booncw@xxxxxxxxxxx>]

I was thinking of declaring two variables (idA and idB), and use a function getVariable() or setVariable(argument) to change it.  So that I can asses information using "scene->body::[idA].get()->state->pos" and it doesn't get messed up.  Or will it still?  

Could you explain more about omp_get_thread_num() and static variable? How can I switch of f parallel processing (scons jobs=1)?


Yours,

Boon
