Summary

Function: vector llGetRegionCorner( );
0.0 Forced Delay
10.0 Energy

Returns a vector in meters that is the global location of the south-west corner of the region the object is in. The z component is 0.0

Divide the returned value by 256 to get the region offset.

Examples

// Calculates your position relative to <0,0,0> of 'Da Boom' in meters when you touch it
vector vecrel; //a sum of llgetpos and llgetregioncorner (and another vector). Saving time doing vector math.

default
{
    state_entry()
    {
        llSetText("Touch me to get your position", <1.0,1.0,1.0>, 1.0);
    }
    
    touch_start(integer total_number)
    {
        vecrel = llGetRegionCorner() + llDetectedPos(0);
        llWhisper(0, "llGetRegionCorner() is:"+(string)vecrel); //for debugging before vector addition
        
        vecrel -= <256000.0, 256000.0, 0.0>;//Da Boom's region corner is at <256000.0, 256000.0, 0.0>
        llWhisper (0, "Position relative to <0,0,0> of 'Da Boom': " + 
        (string)llRound(vecrel.x) + ", " + (string)llRound(vecrel.y) + ", " + (string)llRound(vecrel.z) + ".");
        
        llWhisper(0, "Position relative to <0,0,0> of 'Da Boom':" +(string)vecrel); //faster but unformatted output
    }
}
