EdgeOfWorld

llEdgeOfWorld

Summary

Function: integer llEdgeOfWorld( vector pos, vector dir );

205	Function ID
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

   }
   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" );
   }
