    <p>I am trying to have an object rotate towards the mouse. The problem is that the object always rotates a bit to much to the left, an extra 45 degrees to much to be excact.</p> <p>So for example if my mouse is at such a position that the object should be positioned to the north, thus the rotation value = 0, the object gets rotatated 45 degrees to the left, so 270 degrees and thus pointing left, while it should point north/upwards.</p> <p>This is my code:</p> <pre><code> public override void Update() { base.Update(); GetMousePos(); SetRotation(); } private void GetMousePos() { MouseState ms = Mouse.GetState(); _mousePos.X = ms.X; _mousePos.Y = ms.Y; } private void SetRotation() { Vector2 distance = new Vector2(); distance.X = _mousePos.X - (_position.X + (_texture.Width / 2)); distance.Y = _mousePos.Y - (_position.Y + (_texture.Height / 2)); _rotation = (float)Math.Atan2(distance.Y, distance.X); } </code></pre> <p><b>EDIT: extra info</b></p> <p>These values appear when my mouse is in the right side of the screen. The object should point east/right, but he points north/upwards.</p> <p>MOUSE POS X: 1012</p> <p>MOUSE POS Y: 265</p> <p>OBJECT POS X: 400275</p> <p>OBJECT POS Y: 24025</p> <p>ROTATION: 0</p> <p><b>EDIT 2: how _rotation is used</b></p> <pre><code>public virtual void Draw(SpriteBatch spriteBatch) { int width = _texture.Width / _columns; int height = _texture.Height / _rows; Rectangle destinationRectangle = new Rectangle((int)_position.X, (int)_position.Y, width, height); Rectangle sourceRectangle = new Rectangle((int)((_texture.Width / _columns) * _currentFrame), 0, width, height); spriteBatch.Begin(); spriteBatch.Draw(_texture, destinationRectangle, sourceRectangle, Color.White, _rotation, new Vector2(width / 2, height / 2), SpriteEffects.None, 0); spriteBatch.End(); } </code></pre> <p><b>EDIT 3: The working fix thingy</b></p> <pre><code> protected void SetRotation() { MouseState mouse = Mouse.GetState(); Vector2 mousePosition = new Vector2(mouse.X, mouse.Y); Vector2 direction = mousePosition - _position; direction.Normalize(); _rotation = (float)Math.Atan2( (double)direction.Y, (double)direction.X) + 1.5f; } </code></pre>

    1. COPost the value of `_rotation` for us and the _mousePos.X and _mousePos.Y values.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
