If // the velocity is greater than zero (i.e. the Host is not stationary) the // ConstSpeedMobility module calculates a random target position for the Host. // Depending to the update interval and the velocity it calculates the number of // steps to reach the destination and the step-size. Every update interval // ConstSpeedMobility calculates the new position on its way to the target // position and updates the display. Once the target position is reached // ConstSpeedMobility calculates a new target position. // // This component has been taken over from Mobility Framework 1.0a5. // // @see ChannelControl // @author Steffen Sroka, Marc Loebbers, Daniel Willkomm // simple ConstSpeedMobility parameters: debug : bool, // debug switch vHost : numeric const, // speed of the host (in m/s) updateInterval : numeric const, // time interval to update the hosts position x: numeric const, // start x coordinate (-1 = display string position, or random if it's missing) y: numeric const; // start y coordinate (-1 = display string position, or random if it's missing) endsimple
