Scripting tools to allow display of text on a prim: XyText 1.5 (aka XyText) , XyzzyText, XyyyyzText, XyzzyText-UTF8, ZZText


XyyyyzText is a variation of XyText allowing up to 10 characters on a prim.
It supports different text in each line, instead of one single text which will be broken into the next lines.
Here's a picture on how it looks like: http://screencast.com/t/1wMLujLcEO
It shows the text in reversed order as the prims were linked together.

All scripts are included.

XyyyyzText Setup

The prim size script.
Put this script into one prim, to let it automatically modify itself for use as a text-prim.

XyyyyzText

The cell script. It's still the same as for the XyText 1.5 version.
Put this script into the modified prim above. Copy this prim multiple times to get a larger display.

XyyyyzText Board Control

This script is the board control script. Put it into the ROOT prim of your display linkset.
This was highly modified by me to support different text for each line.
DON'T FORGET TO CHANGE THE FIRST VARIABLE IN THAT SCRIPT!

} </lsl>

Example Use

This is the EXAMPLE usage script. Put this also into the ROOT prim too!
You can then enter a text into the public chat. Seperate each line in that text with a "|"
<lsl> default { 

   state_entry()
   {
       llListen(PUBLIC_CHANNEL, "", NULL_KEY, "");
   }

   listen(integer channel, string name, key id, string message)
   {
       llMessageLinked(LINK_THIS, 1, message, llGetKey());
   }

} </lsl>
