Errors in Vector2 variables

For reasons unknown to me, I am getting these errors in my script :

  • expecting ), found ','
  • ';' expected. Insert a semicolon at the end
  • expecting EOF, found '1' or expecting EOF, found '8'

I found these on both lines declaring Vector2 variables, and in setting them, according to these errors, it seems that it won't take two numbers to set a Vector2 variable. Why is this happening? For context purposes, here is my entire script:

var camera1 : Camera;
var camera2 : Camera;
var camera3 : Camera;
var openButton : Texture2D;
var closeButton : Texture2D;
var mapMarker : Texture2D;
var compass : Texture2D;
var mapSkin : GUISkin;
var characterTransform : Transform;
var screenPos : Vector3;
var playerDirection : Vector2 = (0, 1); //this line is one problem
var deltaRotation : float = 0;
var pivotPoint : Vector2 = (0.898, 8); //this line is the other problem

function Update () {
    if (camera2.enabled) {
        screenPos = camera.WorldToScreenPoint (characterTransform.position);
    }
}

function OnGUI() {
    GUI.skin = mapSkin;
    if (camera1.enabled) {
        deltaRotation = Vector2.Angle(playerDirection,Vector2(characterTransform.forward.x, characterTransform.forward.z));    
        GUIUtility.RotateAroundPivot(deltaRotation,pivotPoint);  
        playerDirection = Vector2(characterTransform.forward.x, characterTransform.forward.z);  
        GUI.DrawTexture(Rect(1145,3,290,290),compass);
        if (GUI.Button(new Rect(1115,270,50,50),openButton)) {
            camera1.enabled = false;
            camera2.enabled = true;
            camera3.enabled = false;
        }
    }
    if (camera2.enabled) {
        GUI.DrawTexture(Rect(screenPos.x - 12,730 - screenPos.y,20,20),mapMarker);
        if (GUI.Button(new Rect(1250,100,100,100),closeButton)) {
            camera1.enabled = true;
            camera2.enabled = false;
            camera3.enabled = true;
        }
    }
}

function Start () { 
    camera2.enabled = false; 
} 

That's not how you define Vector2s.

var playerDirection = Vector2(0, 1);
