News from the Second Life Team – January 2024 Edition <\/span><\/h2>\n

 <\/p>\n

Happy New Year! We\u2019re off to a great start to the year at the Lab and happy to share more Second Life updates with you. You\u2019ll find news on scripting additions, PBR Materials, Project Viewers, and an update on the Second Life Mobile Private Alpha program. Enjoy!<\/p>\n

A handful of new, useful scripting features will be getting released in the coming weeks:<\/p>\n

llComputeHash<\/h3>\n

LSL’s old llMD5 function has a significant flaw: it always adds a “:” character to the input string. This makes it useless for most hashing purposes. Enter: llComputeHash<\/a>! This new function can generate a hash of an input string using any of the following hashing algorithms: md5, md5_sha1, sha1, sha224, sha256, sha384, <\/strong>and sha512<\/strong>.<\/p>\n

llGetNotecardLineSync<\/h3>\n

You know how it takes an incredible amount of time for your furniture to boot up after resetting its scripts? Argh! Yeah, it’s annoying, and likely due to your sofa\/throne\/maypole reading configuration from one or more notecards in its inventory.<\/p>\n

The new llGetNotecardLineSync<\/a> function makes loading data from notecards in object inventory much faster by providing a synchronous access method with the caveat that the notecard must be in the region’s asset cache.<\/p>\n
