General

I regret that there were so many edits, it's the first time I've contributed content to this Wiki, and am still learning the formatting. Thanks for understanding. It would help if there were a generic page with the formatting already in place that users could edit -- there may be one somewhere, but I haven't found it yet. -- Rich

Don't worry about the number of edits. Just look around at the syntax used on other pages, it's the easiest way. Strife Onizuka 04:54, 8 February 2007 (PST)

Different colors in the displayed text?

I recently saw some RPG engine that lets people have colored health bars in the hovertext above their head.

Is there a way to specify colors for individual text characters, or are they doing this by stacking up several llSetText prims, each showing only one color? Scalar Tardis 20:25, 25 March 2008 (PDT)

Stacking. -- Strife Onizuka 15:19, 26 March 2008 (PDT)

llSetText for storage

Regarding the caveat "Do not rely on Floating Text as a storage medium; it is neither secure nor finalized." I'm wondering how necessary some of this is as a caveat anymore?

I'm not aware of the text limit for hover-text having changed in a long time, and even if it were to change that's an argument for checking that any stored data is the length you expect it to be (e.g- store expected length first). The main argument against storage is the lack of security, but the same is true of using prim descriptions, which are also commonly used for storage that can survive resets.

I often use invisible set-text to store short pieces of persistent data that I need to survive resets (but which I'm not concerned about being inspected), while leaving descriptions free for users to change manually (as I like to use descriptions for specifying prim-properties that a script can load, such as allowing a script to change all prims with the "primary" keyword). Obviously pushing the limits of either isn't a great idea, but short text should be fine in both so long as it's nothing sensitive, so I'm wondering if the caveats should be updated to reflect that? The caveats for this page could probably use a cleanup in general actually, as things like clearing text could do with being in examples I think. --Haravikk 01:58, 12 January 2016 (PST)


New Information

Need to add a caveat about llGetDesc

https://jira.secondlife.com/browse/BUG-11311

llSetText(llDumpList2String(llParseStringKeepNulls(llGetObjectDesc(),["\\n"],[]),"\n"),<1.0,1.0,1.0>,1.0);


llSetText doesn't parse llGetDesc properly and can't parse line breaks or other string escapes
