OpenSimulator

Downloading

• Read instructions from:
  • http://opensimulator.org/wiki/Build_Instructions
• Install additional packages
  • sudo apt-get install subversion nant mono-gmcs libmono-microsoft8.0-cil libmono-system-runtime2.0-cil libgdiplus libmono-i18n2.0-cil libmono-oracle2.0-cil
• Download opensim Source code
  • Use stable: 0.6.6-release (SVN version 9961)

Building

• Build steps
  • cd opensim
  • ./runprebuild.sh
  • nant
  • cd bin
  • mono OpenSim.exe
    • or in 32 bits: mono OpenSim.32BitLaunch.exe

Configuring

• Second Life partition the word into regions of 1000 meters x 1000 meters.
• You must define the regions of your simulation
• cd bin
• cd Regions
• and edit (or create this file if it is not there) the file: default.xml

Here is the content of mine:

 <Root>
 <Config sim_UUID="b951b4fd-1c3c-4f95-b008-57e26edafd30" sim_name="OpenSim Test" sim_location_x="1000" sim_location_y="1000" internal_ip_address="0.0.0.0" internal_ip_port="9000" allow_alternate_ports="false" external_host_name="127.0.0.1" master_avatar_uuid="00000000-0000-0000-0000-000000000000" master_avatar_first="test" master_avatar_last="user" master_avatar_pass="test" lastmap_uuid="1f28dfc0-e06a-4060-8f5c-1570bd70d88f" lastmap_refresh="1252162674" nonphysical_prim_max="0" physical_prim_max="0" clamp_prim_size="false" object_capacity="0" scope_id="00000000-0000-0000-0000-000000000000" />
 </Root>%

Note the fields

• "sim name"
• "sim_location_x"
• "sim_location_y"

How to run in your own computer

• From one terminal start the OpenSimulator
• Wait until you see the text:

   10:57:54 - [!]:STARTUP COMPLETE
   10:57:54 - Currently selected region is OpenSim Test
   10:57:54 - [STARTUP]: Startup took 0m 10s
   Region (OpenSim Test) #  

The times in will be different for you (of course).

• Type "help" to see all the possible commands
• Create a user with the following command

      create user   Luke  Skywalker   secretpassword

• See the list of users with the command

      show users

• Then you can go to your SecondLife viewer directory
• and launch it with the command:

    ./SecondLife-i686-1.23.4.123908/secondlife  -loginuri http://127.0.0.1:900

• at that point you should be able to log in, in the simulator that is running in your own computer.
• If you go back to the opensimulator terminal, and type "show users", you should see your name now.
• You could log in other machines' simulators by replacing the localhost address "127.0.0.1" with the IP address of the machine that you want to connect to.
• At this point you can start practicing with the SL Scripting language.
