Re: [Java-player-users] Position and Laser interfaces conflict?

[Radu B. R. <ve...@in...>]

I'm not quite sure what you're experiencing here. The exact same code works
with Javaclient 1.6.2e just fine. By the way, one small note:

- try to use the javaclient.jar file or the classes subdirectory and use
"import javaclient.*;" instead of building your code inside the javaclient
sources (hence, the need for "package javaclient;"). I now realize the need
for some simple examples for our users... We provided the ANT makefile and
shell scripts which should build the classes, the jar and the documentation,
but we forgot to explain that to our users. :(

So your code works fine with player and stage (CVSed) and Javaclient 1.6.2e. 

What version of player/stage are you using, and how does your config/world
file looks like? I'm quite sure this should work with any version, but who
knows... nobody is perfect :)

Cheers,
Radu.
