function
Function syntax
integer llEdgeOfWorld(
  1. vector pos,// Position vector in region coordinates.
  2. vector dir// Direction vector.
);
Returns
integer
Energy
10

Checks to see whether the border hit by dir from pos is the edge of the world (has no neighboring simulator).

The z component of dir is ignored.

Returns an integer value. FALSE indicating there is a simulator in the direction indicated.

How to use
integer result = llEdgeOfWorld(ZERO_VECTOR, ZERO_VECTOR);

Caveats

Section titled “Caveats”
  • If the x and y components of dir are zero (like with ZERO_VECTOR), TRUE is always returned.
  • pos must be in the region.
  • Can only be used to detect directly adjacent regions, not diagonally adjacent regions
  • This function will also return TRUE if llRequestSimulatorData() returns “up” for an adjacent region but that region doesn’t visibly show when standing next to its border.

Examples

Section titled “Examples”
Example 1
//--// 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" );
    }
  }
}
