Member Function Documentation

void inet::LinearRotatingMobilityBase::initializeOrientation ( )

overrideprotectedvirtual

Initializes the orientation from module parameters.

Reimplemented from inet::RotatingMobilityBase.

 {
     MobilityBase::initializeOrientation();
     if (!stationary) {
         setTargetOrientation();
         EV_INFO << "current target orientation = " << targetOrientation << ", next change = " << nextChange << endl;
     }
     lastUpdate = simTime();
     scheduleUpdate();
 }

void inet::LinearRotatingMobilityBase::rotate ( )

overrideprotectedvirtual

Moves according to the mobility model to the current simulation time.

Subclasses must override and update lastPosition, lastSpeed, lastUpdate, nextChange and other state according to the mobility model.

Implements inet::RotatingMobilityBase.

 {
     simtime_t now = simTime();
     if (now == nextChange) {
         lastOrientation = targetOrientation;
         EV_INFO << "reached current target orientation = " << lastOrientation << endl;
         setTargetOrientation();
         EV_INFO << "new target orientation = " << targetOrientation << ", next change = " << nextChange << endl;
     }
     else if (now > lastUpdate) {
         ASSERT(nextChange == -1 || now < nextChange);
         double delta = (simTime() - lastUpdate).dbl() / (nextChange - lastUpdate).dbl();
         lastOrientation = slerp(lastOrientation, targetOrientation, delta);
     }
 }

virtual void inet::LinearRotatingMobilityBase::setTargetOrientation ( )

protectedpure virtual

Should be redefined in subclasses.

This method gets called when targetOrientation and nextChange has been reached, and its task is to set a new targetOrientation and nextChange. At the end of the movement sequence, it should set nextChange to -1.
