{
    argnewtonupdate* arg=(argnewtonupdate*)fpsetworld;
 
    while(!(*(arg->end)))
    {
        if(!(*(arg->pause)))
        {
            (*arg->progress) = IN_PROGRESS;
            SDL_framerateDelay ((arg->manager));
            NewtonUpdate ((arg->nWorld), 1.0f/80.0f);
        }
        else
        {
        SDL_Delay(50);
        }
        (*arg->progress) = IDLE;
    }
    return 0;
}

Je sèche complètement quelqu'un peut il m'aider ??

ps: a noter que je n'utilise pas la fonction NewtonCreateCompoundCollisionFromMesh () qui provoque la segfault dans mon programme.
