I started this project about 1 week before the Scripting Trade Show, but due to sim delays and my time i was never able to attend, i had planned on talking about how to homebrew XY offset scripts, and since i had this quickie already written i thought i would unleash it to the world
this version uses the 5 faced prim, and only displays 1 charater per face, in the near future i will be releasing a single texture 2 charater per face version, but that is another thread
this version is MUCH smaller than normal XY text, and IMO just abit faster
i release this system as openware for anyone to use and and learn from, if you use the scripts in their original form please include a footnote to me in your projects credits
lets get started
5 FACE PRIM SETUP
this is the 5 face prim setup script from the wiki, edited for this system. Two things you need to do manually
1 the center face needs to be flipped on its Horizontal axis
2 if you want fullbright i didnt add it into the setup script

NOTECARD
i used a notecard to avoid scripting issues with charaters such as " and \
this notecard needs to be named text rom please note the space at the end of the line, this needs to be in place for the script to see " " (spaces) in text, also this needs to be saved on line 0 of the notecard

CONTROL SCRIPT
this is the heart of this system, and needs to be placed in the parent prim of the object
display prims are accessed via link numbers from lowest to highest (get your link orders correct heh)
