Script Library

Come to this page to see complex examples that show how to combine parts of LSL.

Go to the LSL Examples page to see brief examples of how to use parts of LSL

Why collect complex examples here? Well, ...

There are many scripts that have become buried in the Scripting Library forum, were lost with the death of the scripting forums, or sit idle in inventories that could be useful and should be more accessible.

Other scripters may be in the same situation. This wiki is a well-suited medium for a script library. Feel free to add your scripts to the script library by creating new pages for them and linking to those pages here.

Note that there are many more scripts in the LSL Library here, but you can't get to them if you don't know they exist, because they are subpages now, instead of an automatically updated category. Good luck searching.

Rules for posting:

  1. Your script must be tested and working. If it's not, stick it in your user-space until it is. This is a list of working, usable scripts.
  2. Add a link to your script's page here. Link back to this page from your script's page. Start your page with {{LSL Header}}.
  3. Do not add scripts that duplicate the same functionality as an existing script or built in function. If yours does, explain why.
  4. Do not list simple scripts here. Include those among the LSL Examples instead.
