Re: [Java-player-users] Using latest Javaclient with Player 1.6.4

[Josh B. <jj_...@ou...>]

Radu,

We're hesitant to switch to Player 2.0.  This is for an undergraduate
robotics class and we're already throwing enough at the students.=20
Adding an untested code base to the situation doesn't seem like a
great idea.  Specifically, we're the most worried about the
documentation.  Player 1.6.5 didn't have the greatest documentation,
and I don't know how much further behind Player 2.0 and Javaclient 2.0
will be.

I'm actually using SWIG at the moment to generate an interface for
libgazebo.  Going straight into libgazebo lets me run simulations much
faster than real time.  As a long term goal I want to create a higher
level interface that can use libgazebo for faster than real time
simulations, or player for controlling real robots.
