Re: [Playerstage-users] establish a group of robots using "for" loop, but doesn't work

[jiajia <jia...@16...>]

Hi,
  Actually, I try this:
  my .cc is:
   int
   main(int argc, char *argv[])
   {
     parse_args(argc,argv);
     using namespace PlayerCc;
     PlayerClient* robot[popsize];
     Position2dProxy* pp[popsize]; 

     LaserProxy* lp[popsize];
       for(int i=0;i<popsize;i++)
  {
     robot[i] =new PlayerClient("localhost", 6665+i);
     pp[i] = new Position2dProxy(robot[i], 1);
     lp[i] = new LaserProxy(robot[i], 0);
     pp[i].SetMotorEnable (true);
  }
       robot[0].read();
       .........
}
   
     Everything has the same problem.
     for robot, it says :
         The request to 'read' is in ' robot[0]', but 'robot[0]' is not a class type of 'PlayerCc::PlayerClient*’.
     for pp, it says:
         The request to 'SetMotorEnable' is in ' pp[i]', but 'pp[i]' is not a class type of 'PlayerCc::Position2dProxy*’.  
     something like the above.

     Thanks again!

Hi Toby,
   Thanks for your rely.
   After I try " PlayerClient * robot[popsze]; " instead of " PlayerClient robot[popsize]; ", the above error disappears.  But, when I try to use " robot[0] .read", it says:
   error:
    The request to 'read' is in ' robot[0]', but 'robot[0]' is not a class type of 'PlayerCc::PlayerClient*’.
    (the error is not written in English, and I translated it as above.Maybe it is not clear. Sorry)
    
    Thanks for your time~

You are creating an array of robots and then assigning a robot pointer to an individual item.

You probably want
PlayerClient * robot[popsze];

dear my friends,
      Sorry to bother you~
      I really want to establish a group of robots using "for" loop, but it doesn't work!
      My .cc is 
      int
      main(int argc, char *argv[])
     {
       parse_args(argc,argv);
      using namespace PlayerCc;
       PlayerClient robot[popsize];  
      for(int i=0;i<popsize;i++)
      {
          robot[i] =new PlayerClient("localhost", 6665+i);
      }
      }
      
     My .cfg and .world are right, for I previously use them to configure other programs.
    
     Errors are:
    **.cc: In function ‘int main(int, char**)’:
    **.cc:47: 错误： no match 为‘operator=’在‘robot[i] = (std::basic_string<char, std::char_traits<char>, std::allocator<char> >(((const char*)"localhost"), ((const std::allocator<char>&)((const std::allocator<char>*)(& std::allocator<char>())))), (((PlayerCc::PlayerClient*)operator new(64u)), (<statement>, <anonymous>)))’中
/usr/local/include/player-2.1/libplayerc++/playerclient.h:104: 附注： 备选为： PlayerCc::PlayerClient& PlayerCc::PlayerClient::operator=(const PlayerCc::PlayerClient&)

  Sorry for my poor C++. Waiting for rely.
  Thanks a million!!!!
