A 2 prim HUD targets nearby players names, profiles and user key. Drop this into the root prim of 2 linked prims. Modify it to suit your particular use in another Hud, weapon, or whatever you want. <3 --Ackley Bing
// Target Crosshair HUD
// by Ackley Bing
// Save this script into the root prim of 2 linked prims (2 ordinary wooden cube prims - linked)
//
// This is based on my Basic Target Scanner HUD
// (http://wiki.secondlife.com/wiki/Basic_Target_Scanner_HUD)
// Now you get a crosshair that follows your target
// thanks to Cerise Sorbet's HUD Dots Radar
// (http://wiki.secondlife.com/wiki/HUD_Dots_Radar)
//
// Changes in 0.5.1.2
// 1. UpdateCrosshair():
// Bugs fixed where crosshair and hud info didn't match up.
// Info still buggy sometimes. Don't click too fast! :)
// 2. Identify():
// Avatar list sort ascending.
//
// If you cant see the hud, Wear or Add again should fix the problem.
