A demonstration script. The object containing this script will be stopped from reaching the programed destination. The physics will be removed and the script will error (needing to be reset).
llSetStatus(STATUS_PHYSICS | STATUS_SANDBOX, TRUE); // Switch physical and sandbox on.
llMoveToTarget(llGetPos() + <0.0, 0.0, 20.0>, 1.0); // Attempt to move to a point outside the "sandbox".
// After being stopped, physics can only be enabled again when the object is moved back to within the "sandbox".
// If the script is reset (manually or by a call to llResetOtherScript from another script in the same prim)...
// ...the sandbox center will be reset to the objects position at that time.
// Very handy when developing physical objects that may not behave as expected.
