    <p>I am trying to figure out how to use the origin in Draw method to rotate a sprite around its center. I was hoping somebody could explain the correct usage of origin parameter in Draw method.</p> <p>If I use the following Draw method (without any rotation and origin specified) the the object is drawn at the correct/expected place:</p> <pre><code>spriteBatch.Draw(myTexture, destinationRectangle, null, Color.White, 0.0f, Vector2.Zero, SpriteEffects.None, 0); </code></pre> <p>However, if I use the origin and rotation like shown below, the object is rotating around is center but the object is floating above the expecting place (by around 20 pixels.)</p> <pre><code>Vector2 origin = new Vector2(myTexture.Width / 2 , myTexture.Height / 2 ); spriteBatch.Draw(myTexture, destinationRectangle, null, Color.White, ballRotation, origin, SpriteEffects.None, 0); </code></pre> <p>Even if I set the ballRotation to 0 the object is still drawn above the expected place</p> <pre><code>spriteBatch.Draw(myTexture, destinationRectangle, null, Color.White, 0.0f, origin, SpriteEffects.None, 0); </code></pre> <p>Is seems that just by setting the origin, the placement of the object changes.</p> <p>Can somebody tell me how to use the origin parameter correctly.</p> <hr> <h1>Solution:</h1> <p>Davor's response made the usage of origin clear. The following change was required in the code to make it work:</p> <pre><code>Vector2 origin = new Vector2(myTexture.Width / 2 , myTexture.Height / 2 ); destinationRectangle.X += destinationRectangle.Width/2; destinationRectangle.Y += destinationRectangle.Height / 2; spriteBatch.Draw(myTexture, destinationRectangle, null, Color.White, ballRotation, origin, SpriteEffects.None, 0); </code></pre>

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.
