Error with mouse cursor.

Hi, I am having some errors with my Mouse Center script. Can someone please help me?

Here are the 2 errors.

NullReferenceException: Object reference not set to an instance of an object Boo.Lang.Runtime.RuntimeServices.GetDispatcher (System.Object target, System.String cacheKeyName, System.Type[] cacheKeyTypes, Boo.Lang.Runtime.DynamicDispatching.DispatcherFactory factory) Boo.Lang.Runtime.RuntimeServices.GetDispatcher (System.Object target, System.Object[] args, System.String cacheKeyName, Boo.Lang.Runtime.DynamicDispatching.DispatcherFactory factory) Boo.Lang.Runtime.RuntimeServices.SetProperty (System.Object target, System.String name, System.Object value) Mouse Cursor.Update () (at Assets/Horror Game Files/Scripts/Mouse Cursor.js:34)

Here is the script. (Below)

var normalCursor : Texture2D; // The texture for when the cursor isn't near a screen edge var leftCursor : Texture2D; // The texture for the cursor when it's at the left edge var rightCursor : Texture2D; // Ditto, right edge var upCursor : Texture2D; // Top edge var downCursor : Texture2D; // ...And bottom edge var nativeRatio = 1.3333333333333; // Aspect ratio of the monitor used to set up GUI elements private var lastPosition : Vector3; // Where the mouse position was last var normalAlpha = .5; // Normal alpha value of the cursor ... .5 is full var fadeTo = .2; // The alpha value the cursor fades to if not moved var fadeRate = .22; // The rate at which the cursor fades private var cursorIsFading = true; // Whether we should fade the cursor private var fadeValue : float;

// Scale the cursor so it should look right in any aspect ratio, and turn off the OS mouse pointer function Start() { // Slightly weird but necessary way of forcing float evaluation var currentRatio : float = (0.0 + Screen.width) / Screen.height; transform.localScale.x *= nativeRatio / currentRatio; Screen.showCursor = false; fadeValue = normalAlpha; lastPosition = Input.mousePosition; }

function Update() { var mousePos = Input.mousePosition; // If the mouse has moved since the last update if (mousePos != lastPosition) { lastPosition = mousePos; // Get mouse X and Y position as a percentage of screen width and height MoveMouse(mousePos.x/Screen.width, mousePos.y/Screen.height); } // Fade the alpha of the cursor if (cursorIsFading) { guiElement.color.a = fadeValue; fadeValue -= fadeRate * Time.deltaTime; if (fadeValue < fadeTo) { fadeValue = fadeTo; cursorIsFading = false; } } }

function MoveMouse(mousePosX : float, mousePosY : float) { // Make the cursor solid, and set fading to start in case mouse movement stops guiElement.color.a = fadeValue = normalAlpha; guiElement.texture = normalCursor; cursorIsFading = true;

 // If the mouse is on a screen edge, first make sure the cursor doesn't go off the screen, then give it the appropriate cursor
 if (mousePosX < .005) {
     mousePosX = .005;
     guiElement.texture = leftCursor;
 }
 if (mousePosX > .995) {
     mousePosX = .995;
     guiElement.texture = rightCursor;
 }
 if (mousePosY < .005) {
     mousePosY = .005;
     guiElement.texture = downCursor;
 }
 if (mousePosY > .995) {
     mousePosY = .995;
     guiElement.texture = upCursor;
 }
 
 transform.position.x = mousePosX;
 transform.position.y = mousePosY;

}

Can someone please help me out with these errors? Thanks.
