As soon as I set more than one Image to the same RotateTransform the images failed to rotate.

Let me know if you see otherwise with RotateTransform.

Here is my code:

public partial class Page : UserControl

{

RotateTransform rt = new RotateTransform();

private Storyboard _gameLoop = new Storyboard();

public Page()

{

InitializeComponent();

rt.CenterX = 32;

rt.CenterY = 24;

Image1.RenderTransform = rt;

Image2.RenderTransform = rt;

this.Loaded += new RoutedEventHandler(Page_Loaded);

}

void Page_Loaded(object sender, RoutedEventArgs e)

{

_gameLoop.Duration = TimeSpan.FromMilliseconds(0);

_gameLoop.Completed += new EventHandler(MainGameLoop);

_gameLoop.Begin();

}

private void MainGameLoop(object sender, EventArgs e)

{

rt.Angle += 5;

rt.Transform(new Point(32, 24));

_gameLoop.Begin();

}

I dont have my code right here, but im pretty sure i have several images that share the same ScaleTransform. That way i can scale them all uniformly by setting the ScaleX and ScaleY of that one ScaleTransform. I would suspect the same would be true for the RotateTransform?

syntax42 - Each image must have its own render transform, in Silverlight you can not share this object. Also, it would be needed if you want the images to rotate independently of each other at different angles.

chrisaswain - I went back and tried the Sprite class as a UserControl (Sprite.xaml + Sprite.cs) and as a custom Control (just Sprite.cs with template) and I found the FPS to be the same for both.

I'm not sure I understand the benefit of the sprite inheriting from Control instead of the typical UserControl. You seem to imply it's for performance. Could you elaborate on that?
