Summary

Function: llMoveToTarget( vector target, float tau );

Critically damp to target in tau seconds (if the script is physical)

• vector target – region position
• float tau – seconds to critically damp in

To stop the object from maintaining the target positions use llStopMoveToTarget
To change the rotation in the same manner use llLookAt or llRotLookAt.

Examples

default
{
    state_entry()
    {
        vector pos = llGetPos();
        llSetStatus(STATUS_PHYSICS, TRUE);
        // Little pause to allow server to make potentially large linked object physical.
        llSleep(0.1);
        llMoveToTarget(pos,0.4);
        // Look for owner within 20 metres in 360 degree arc every 1 seconds.
        llSensorRepeat("", llGetOwner(), AGENT, 20.0, PI,1.0);
    }
    sensor(integer total_number)
    {
        // Get position of detected owner
        vector pos = llDetectedPos(0);
        // Offset back one metre in X and up one metre in Z based on world coordinates.
        // Offset relative to owner is possible but beyond the scope of this example.
        vector offset =<-1,0,1>;
        pos+=offset;
        llMoveToTarget(pos,0.4);     
    }
}
