[Playerstage-users] Simple c++ question

[bob b. <bob...@gm...>]

I am trying to pass a laserProxy to a function and am getting some errors.
Its been awhile since I used c++ so hopefully this is just a newbie thing,
but if anyone can let me know how to pass a proxy like this I'd appreciate
it!

----------
#include <iostream>
#include <libplayerc++/playerc++.h>
#define MAXSPEED 0.6 //max speed of the robot
#define MAXRANGE 8  //max range of the laser

using namespace PlayerCc;
using namespace std;

// have code that works, just simplifying for now.
int getWallDirection(LaserProxy sp)
{ return(0); }


int main(int argc, char *argv[])
{
 using namespace PlayerCc;
 using namespace std;
  PlayerClient    robot("localhost", 6665);
  //this is to change the order in which the data is stored
  robot.SetReplaceRule(true,-1,-1,-1);
  robot.SetDataMode(PLAYER_DATAMODE_PULL);

  //use proxies
  LaserProxy      sp(&robot,0);
  Position2dProxy pp(&robot,0);

  //Read several times before the robot actually starts getting data
  robot.Read();
  for(int i = 0; i<5 ; i++)
  {
    robot.Read();
  }
  int wallDirection = 100; // 0 is stright, -1 right, +1 left.
  wallDirection = getWallDirection(sp);

  std::cout << "Final Answer : -1 right, 0 straight, 1 left ///   " <<
std::endl;
  std::cout << wallDirection << std::endl;
}
