Summary

Function: integer llEdgeOfWorld( vector pos, vector dir );
0.0 Forced Delay
10.0 Energy

Checks to see whether the border hit by dir from pos is the edge of the world (has no neighboring simulator)
Returns an integer that is a boolean.

• vector pos
• vector dir

Caveats

  • Zero direction vector (ZERO_VECTOR) always returns TRUE.
  • pos must be in the region.
  • Can only be used to detect directly adjacent regions, not diagonally adjacent regions

Examples

<lsl> //--// Tells if there are neighboring sims on touch //--//

default{

 touch_start( integer vIntTouched ){
   vector vPosObject = llGetPos();
   if (!llEdgeOfWorld( vPosObject, <0.0, 1.0, 0.0> )){
     llOwnerSay( "There is a Sim to the North" );
   }
   if (!llEdgeOfWorld( vPosObject, <1.0, 0.0, 0.0> )){
     llOwnerSay( "There is a Sim to the East" );
   }
   if (!llEdgeOfWorld( vPosObject, <0.0, -1.0, 0.0> )){
     llOwnerSay( "There is a Sim to the South" );
   }
   if (!llEdgeOfWorld( vPosObject, <-1.0, 0.0, 0.0> )){
     llOwnerSay( "There is a Sim to the West" );
   }
 }

}
