EdgeOfWorld

llEdgeOfWorld

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, TRUE indicating there is a simulator in the direction indicated.

• vector	pos	–	position
• vector	dir	–	direction

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" );
   }
 }

}
