LlEdgeOfWorld

Summary

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

Checks to see whether the border hit by dir from pos is the edge of the world (has no neighboring simulator).
Returns a boolean (an integer) value. FALSE indicating there is a simulator in the direction indicated.

• vector pos position in region coordinates
• vector dir direction

The z component of dir is ignored.

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

Examples

//--// 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" );

The world once though flat
indeed has come full circle
here there be dragons.
