Actionscript 2 collison detection

[***]

HI,
I am trying to make a game where you are a Pacman type guy, with an ak-47, and i have enemies, but i want to know how to make something happen When you hit them, like you die or something.

The dude you are is called 'turret', and the enemies are callled 'enemy' (and randomly appear)

Thanks.

if(enemy[i].hitTest(turret))
{
  enemy[i]._x = Math.random(400);
  enemy[i]._y = Math.random(400);
  turret.health-=5;
}
