This guide assumes all deprecation warnings have been addressed, since the deprecated APIs have been removed.

User callback

When calling f3d::interactor::start() or f3d::interactor::playInteraction(), it was possible to set a user callback automatically called at each event loop. If you were setting such callback, please call f3d::interactor::setEventLoopUserCallback() manually before calling start() or playInteractor(). The callback takes an argument of type f3d::interactor::interactor_state_t allowing you to retrieve useful information about the interactor state.
