Re: [Playerstage-users] simulationProxy Get/Set Property

[Jenny O. <jo...@cs...>]

In swarm.world do you have a model which you've named hc1 that has a 
fiducial finder attached to it?
Maybe in the world file, you've described a model hc1 but haven't 
actually declared any instances of it.

/playerc error   : got NACK from request
/usually means that there's a problem connecting your cfg to the world, 
or your code to the cfg.
So does your .cfg file declare a driver or a model that isn't actually 
in the world? Does your code try and declare or use a proxy that isn't 
in the cfg?
The code you've included looks ok, so I would guess the problem is in 
swarm.worlds somewhere.
