Moving a gameobject on a certain direction

Hi,

So, I have two gameobjects, a player and a crosshair. The crosshair is always 20 units in the forward direction of the player, with its y value set to 0. What I would like is to launch another gameobject, a projectile, from the player, to the crosshair. This is what I attempted.

When the player presses space, I run this little script

Instantiate( missile, transform.position, transform.rotation);

And in the missile start function I do this.

Vector3 direction = crosshair.transform.position - player.transform.position; direction.Normalize();

and in the Update function for missile, I do this

transform.Translate((direction moveSpeed Time.deltaTime));

But I get wierd results, it works when the player is facing a certain direction, but as it rotates, the direction keeps getting more and more inaccurate.

Any ideas?
