Re: [Playerstage-users] how two robots interact in P/S?

Dear Toby:

  I have searched in the forum for a day, but I haven't found out the 
effective way to solve the problem as following when i run the program for 
testing two -robot communication: 
playerc error   : got NACK from request 
playerc error   : failed to get response 
terminate called after throwing an instance of 'PlayerCc::PlayerError' 
Aborted (core dumped) 
this is my com.cc file(similar to other has posted) 
#include <libplayerc++/playerc++.h> 
#include<stdio.h> 
//#include <libplayerc/player.h> 
#include "math.h" 
#include <iostream> 
#include "args.h" 
using namespace PlayerCc; 
using namespace std; 
PlayerClient r1("localhost",6665);// 
Position2dProxy pp1(&r1); 
LaserProxy lp1(&r1); 
OpaqueProxy op1(&r1); 
player_opaque_data_t op1Data,op2Data; 
uint8_t op1GetData[1024]; 

PlayerClient r2("localhost",6665);// 
Position2dProxy pp2(&r2, 0); 
LaserProxy lp2(&r2, 0); 
OpaqueProxy op2(&r2,0); 
 uint8_t op2GetData[1024]; 
int 
main(int argc, char **argv) 
{ 
 parse_args(argc,argv); 

for(;;) 
{ 
  r1.Read(); 
  r2.Read(); 
  pp1.SetSpeed(0.5,dtor(30)); 
  pp1.SetSpeed(0.5,dtor(30)); 
 op1Data.data = new uint8_t[3];" 
  op1Data.data_count = 3; 
  op1Data.data[0]='a'; 
  op1Data.data[1]='b'; 
  op1Data.data[2]='c'; 
// send the data structure to opaque proxy 
      op1.SendCmd(&op1Data); 
      std::cout << "Sent Data"<< op1Data.data << std::endl; 
// get back the opaque data 
      uint count = op2.GetCount(); 
      std::cout << "Sent Count" << count << std::endl; 
      op1.GetData(op2Data.data); 
      std::cout << "op1GetData[0]=" << op1GetData[0] << std::endl; 
      std::cout << "op1GetData[1]=" << op1GetData[1] << std::endl; 
} 
return 0; 
} 
 Could you tell me how to solve the problem??I am really impatient. Please
give me a hand. 
Thank you!

Dear Toby:
    I will try the method you advised to me. Thanks again!
    Happy everyday!
