<lsl>// HTML Based, Single Script HUD // This is intended to be a tech demo of what html on a hud allows. // * Interaction with SL world (give items, play animations, scan nearby avatars) // * Simple, low overhead (1 scripts, 1 prim) // * Rich, dynamic interface (images, menus, flash) // Updates and improvements are welcome at http://wiki.secondlife.com/wiki/HTML_HUD_Demo
// To Use: // * Create a cube and wear it as a hud on the top-left. (script will need tweaking for other spots) // * Edit the cube while wearing it and add this script to it. // * Add any animations you want to play to the object // * Add any notecards or objects you want to give away to the object.
