CreateInstanceHook: world file not found for sampleworld

My latest hurdle with getting the Multiverse world server running from trunk on my Ubuntu box was that the instance server couldn't find the world files that were specified in config/sampleworld/startup_instance.py:

Code:

instance.out:ERROR [2012-06-08 19:36:44,035] Instance-2          CreateInstanceHook: world file not found fileName=../config//.mvw
instance.out:ERROR [2012-06-08 19:36:44,043] Instance-4          CreateInstanceHook: world file not found fileName=../config//bigbrother.mvw
instance.out:ERROR [2012-06-08 19:36:44,049] Instance-6          CreateInstanceHook: world file not found fileName=../config//frontier.mvw
instance.out:ERROR [2012-06-08 19:36:44,061] Instance-8          CreateInstanceHook: world file not found fileName=../config//video.mvw

Checking that startup_instance.py file, here's what it's trying to load:
"$WORLD_DIR/$WORLD_NAME.mvw"
"$WORLD_DIR/bigbrother.mvw"
"$WORLD_DIR/frontier.mvw"
"$WORLD_DIR/video.mvw"

In server/plugins/InstanceClient.java, WORLD_DIR is set to $MV_HOME/config/$WORLD_NAME. OK, so it looks like WORLD_NAME is missing from the path. It's also missing from the first filename, so not getting set.

There's a problem with the multiverse.sh script where it isn't picking up the multiverse.worldname setting from the multiverse.properties file. It's supposed to use that to set the MV_WORLDNAME variable, which is used to set WORLD_NAME.

If you specify the world name as a commandline argument for multiverse.sh like this, WORLD_NAME gets set and the instance server finds the .mvw files and runs successfully:

Code:

./multiverse.sh -w sampleworld -v start

I am now able to log into the sampleworld running on my own server using the source files from svn trunk. It has a working master and you can create a character and walk around. Victory!

Nice, if I could have gave you a thumbs up I would. Good job and don't forget to post on the wiki instructions on how to resolve the problems that you had.
