Re: [Java-player-users] [java-player-users] RangerInterface not working LaserInterface does?

[Sebastian R. <seb...@go...>]

Hello Jorge,

Sounds like really good news.

In order to verify your bugfixes I've found the following compile error:
Looks like the (new) PLAYER_POSITION2D_CMD_VEL_HEAD type is not yet defined (in PlayerConstants.java).
I checked out the latest revision (104) from svn repository.

Kind regards,
Sebastian
