Sim Line Insurance Function (getLocalVec())

I just wanted to post a helpful utility function I use when manipulating object's moverment when close to a sim border.

The behavior with llMoveToTarget() and llSetPos() is that they move to the vector specified within the current sim, so... if the object moving happens to cross a sim border while moving, it completely throws the movement off.

vector getLocalVec(vector localCoords, vector regionCorner)
{
    vector simOffset = regionCorner - llGetRegionCorner();
    return simOffset + localCoords;
}

Basicly, what it does, is convert a local vector and a regionCorner into a vector that when put into moveToTarget() or setPos() *always* points to one global position, that doesn't change relative to what sim your in (just make sure you re-call this function when you cross a sim border).

Ive had many situations where this function would be useful, espicially where a physical object was moving and had the potential to cross a sim border.

Example usage:

vector startPos;
vector startSim;

vector getLocalVec(vector localCoords, vector regionCorner)
{
    vector simOffset = regionCorner - llGetRegionCorner();
    return simOffset + localCoords;
}

setPos(vector destination)
{
    llSetStatus(STATUS_PHYSICS,FALSE);
    float distance = llVecDist(destination,llGetPos());

    while(distance > 0)
    {
        llSetPos(destination);
        distance = llVecDist(destination,llGetPos());
    }
}

default
{
    state_entry()
    {
        startSim = llGetRegionCorner();
        startPos = llGetPos();
        llSetStatus(STATUS_PHYSICS,TRUE);
        llApplyImpulse(<5,0,0>,FALSE);
        llSetTimerEvent(1);
    }
    timer()
    {
        if(llVecDist(llGetPos(),startPos) > 30)
        {
            setPos(startPos,startSim);
        }
    }
}
