Created A Gameobject when Pressing a button near player?

I want to create a sword animation when the person click the left mouse button which it fire1, but the problem is the character is moving around and so the location cannot be a specific place but where the player is at... "How Do i make it if the person presses the "Fire1" Button a sword will appear near the player doing an animation of a slash"

This is what i got :(

var weapon : GameObject;

function OnMouseClick ("Fire1"); {

player = new GameObject("weapon");

player.AddComponents("BoxCollider"); }
