XNA SpriteSheet not working - windows-phone-7

Question

I have added logic to show the Sprite animating but it's simply not showing on the screen. What am I doing wrong?
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Content;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input.Touch;
namespace MyXNAGame.Game_Classes
{
public class Player : Sprite
{
private int _frameCount = 6;
private int _frameIndex;
private Rectangle[] _frames;
public float _jumpVelocity = 12f;
public PlayerState _playerState;
public Rectangle BoundingBox
{
get { return new Rectangle {X = (int) Position.X, Y = (int) Position.Y, Height = Texture.Height, Width = Texture.Width}; }
}
public void Initialize()
{
_frames = new Rectangle[_frameCount];
int width = Texture.Width / _frameCount;
for (int i = 0; i < _frameCount; i++)
{
_frames[i] = new Rectangle(i*width, 0, width, Texture.Height);
}
}
public void Load(ContentManager contentManager, string assetName)
{
Texture = contentManager.Load<Texture2D>(assetName);
}
public void Update(GameTime gameTime)
{
while (TouchPanel.IsGestureAvailable)
{
GestureSample gestureSample = TouchPanel.ReadGesture();
if (gestureSample.GestureType == GestureType.Tap)
{
if (_playerState == PlayerState.Running)
{
_playerState = PlayerState.NormalJump;
}
}
if (gestureSample.GestureType == GestureType.Hold)
{
if (_playerState == PlayerState.Running)
{
_playerState = PlayerState.LongJump;
}
}
}
// NormalJump Logic
switch (_playerState)
{
case PlayerState.NormalJump:
Position.Y -= _jumpVelocity;
_jumpVelocity -= 0.5f;
if (_jumpVelocity == 0)
{
_playerState = PlayerState.Falling;
}
break;
case PlayerState.LongJump:
Position.Y -= _jumpVelocity;
_jumpVelocity -= 0.5f;
if (_jumpVelocity == 0)
{
_playerState = PlayerState.Falling;
}
break;
case PlayerState.Falling:
Position.Y += _jumpVelocity;
_jumpVelocity += 0.5f;
break;
case PlayerState.Running:
_frameIndex++;
if (_frameIndex > 5)
{
_frameIndex = 0;
}
break;
}
}
public void Draw(SpriteBatch spriteBatch)
{
spriteBatch.Draw(Texture, Position, _frames[_frameIndex], Color.White, 0, new Vector2(0, 0), new Vector2(0, 0), SpriteEffects.None, 0);
}
}
}`
Can anyone see the obvious mistake? I am using WP7

Answer 1

I changed the 'Scale' parameter in the Draw() method from new Vector(0,0) to new Vector(1,1) as obviously, having a Scale of 0 will not show anything at all.
