Depends which way you did it.. If you did it using health variable then you'd say; when health < 1 wait 7 seconds goto 'respawn point'. If not; then you must have (or at least should) have used broadcasting. So you have (or atleast u'll need) a broadcast for dead. When enemy recieves 'dead' set <where it died variableX> to X and set <where it died variableY> to Y. repeat 7 times wait 1 second, set X to <where it died variableX>, set Y to <where it died variableY>.
You then have a variable for when it dies (X and Y). I reccomend the first option as it is easiest and less fiddly. Hope it helps! ~anuw
