Scripts have been corrected and working properly now
Rezzes a ball for each avatar in range. Each ball tracks it's on AV and displays distance.
Scanner/Rezzer Script
Place this script in a prim along with the scan ball. When touched it will scan the surrounding area and rezz a ball for each avatar.
Suggestion: Create a sphere with a diameter of 2 meters. Set transparency about 60. Create another sphere about 0.05 diameter, color a dark color and put it in the center of the large prim. Select small prim 1st and then large prim and link them. This will give you a center point to reference. The scan ball script is set to scan for it's avatar to a range of 96 meters.
This formula: vector avDivPos = (avPos - rPos) * 0.010417; Takes the (avatars position - position of scanner) & multiplies by (radius of the distance you want the balls to go(2 meter sphere = 1 meter radius)/scan range(96meters)):
1/96 = approximately 0.010417.

Scan Ball Script
Place this script in a prim and make sure to name it "scan ball". Then place the prim into the inventory of the Scanner/Rezzer.
Suggestion; Create a sphere prim of 0.05 diameter with glow set about .80. <lsl> ////////////////////////////////////////////////////////////////////////////////////////////////////// // 3D Radar 2.5 // "Oct 15 2008", "18:44:36" // Creator: Jesse Barnett // Released into the Public Domain //////////////////////////////////////////////////////////////////////////////////////////////////////
