[Playerstage-users] Java client... blobfinder and wheels control

[Hugo G. M. <hg...@es...>]

Hi...

I'm starting to make my way through Player Stage and I started by changing
the Test.java in order to make clear in my mind how the Java Client works...

1. However I have some really strange results... If I run the code below I
can manage to have the position of the agent updated in every step...
However if I uncomment the apparently innocent LaserPlayerDevice line I only
have the first position and it is not updated in the println...


2. I'll need in the future the blogfinderdevice which I didn't find in
java... Does someone know if I can find it somewhere?

3. According with what I saw so far... In order to move you give parameters
like speed and angles... Can I control the wheels individually... Instead of
using this sort of higher-level functions?


Thanks in advance...

     robot.runThreaded(-1, -1);

     for(int i = 0; ; i++) {
        robot.readAll();
 
       for(int j = 0; j < 100000000; j++){}

       ppd.setSpeed(100, 0);
       System.out.println(ppd.getX() +  " " + ppd.getY());
     }
  }
