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 in region coordinates | |
| • 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" );
}
}
}
