About OpenSimulator scripting

An important ingredient in virtual worlds simulation is scripting.
Scripts allow the addition of actions to 'entities' in world, like making a door react to a touch and open.
Since version 0.9.1.0, you can chose between old XEngine or new YEngine script engines.
Script engines do script compilation and control script execution.

A script is not a like a full program, it is a set of blocks of code called when some event happens, like a touch on the door.
Many of those events happen at time critical moments, so those blocks should be small and fast to reduce impact on the rest of simulation.
YEngine may allow long processing to happen with less impact on the simulation, but that will happen at lower priority.


OpenSimulator script language supports a subset of the Linden Labs Second Life script language (LSL) plus its own extensions (OSSL).

LSL (Linden Scripting Language)
OSSL

Configuring scripting

There are a number of parameters that can be tweaked for scripting, such as those which enable OSSL commands or increase the limits on certain script facilities (e.g. listeners).

For standalone and small grid use, the default scripting settings should be fine. See Configuring Scripting for information on configuring these parameters.

How to use scripts in OpenSimulator

If you have never written a script in LSL before, then please have a look at the LSL wiki to learn the scripting basics. If you do have (some) experience with writing or editing LSL scripts, then the procedure is identical to the procedure on SL. Known problems:

  • Error messages about scripting errors are often cryptic, and tend to be long.
  • Script syntax and execution may depend on the engine used, old XEngine or YEngine
  • On teleports or crossings from a region using YEngine to a region using XEngine, script state (like changed values on global variables) is lost. Should be okay on the inverse direction.

Additional Resources for Scripting (LSL)

There have been many questions regarding scripts and tools for scripting lately. Presented here are a variety of Links to Resources which will help most people with Scripting LSL.

OpenSimulator Specific Materials:

Suggested Links for LSL wikis:

Note the Tutorials, Examples & Script Libraries

Off-World Local LSL Editing Tools & Syntax Highlighters

Note: most do not support osFunctions

All EDITORS (no osFunctions) Windows version availableMacOSX version availableLinux version available

In this repository you can find the syntax grammar, syntax highlighting and snippet files for the Linden Scripting Language (LSL) of Second Life for different kinds of software.

LSL EDITOR (no osFunctions) Windows version available

Now an Open Source project. New release is February 2012 (Ver.2.44.2). A valuable tool and easy install.

LSL Plus (no osFunctions) Windows version availableMacOSX version availableLinux version available

Open source Eclipse plugin. Regular updates. Not quite as quick to get installed as LSLEditor, but very good tool.

Notepad++ (osFunctions supported with add-on UDF) Windows version available

Windows only Editor with enhanced capabilities & supports most languages. Very powerful & feature rich.

KATE (no osFunctions) Windows version availableMacOSX version availableLinux version available

Free and open source text editor, supporting lots of scriptinmg and programming languages out of the box. This includes LSL.

Sublime Text 2 (os*/wl*/mod* functions supported with the bundle below) Windows version availableMacOSX version availableLinux version available

Completions & syntax coloring of LSL/OSSL functions/events/constants & in-world editor look-and-feel theme.
To use OSSL feature, use ".ossl" for your script file extension.
It is currently compatible with LL v3.4.1 and OpenSimulator v0.7.4+ (master r/21068).

FS2LSL Graphical editor (LSL OSSL) Windows version availableMacOSX version availableLinux version available

Free and open source text editor, Online-Offline LSL/OSSL Graphical script editor for WEB Browser or Windows (Programming for beginners)

More editors are listed at http://wiki.secondlife.com/wiki/LSL_Alternate_Editors


Syntax Highlighting

  • Scriptastic - Block Based Script Building Tool (like Scratch) making LSL Scripting Simple Enough Even for Kids
  • GitHub FS2LSL - FS2LSL Online-Offline LSL/OSSL script editor for WEB or Windows (Programming for beginners)

Additional Resources for Scripting (OSSL)

There have been many questions regarding scripts and tools for scripting lately. Presented here are a a few links to Resources which will help most people with OSSL scripting.

How to contribute

The ScriptEngine is being developed by many developers. New developers are always welcome. If you want to contribute, even just a tiny little bit, have a look at the OpenSim.Region.ScriptEngine page. There is a lot of developer activity on IRC (Support), feel free to drop in.
