In XNA I can reflect a Sprite with the "SpriteEffects".
And in the DE?

And in the DE? What does "reflect a sprite" mean? Do you mean flipping it? You can rotate it or pass custom points to it rotating or flipping it. There is also a switch in MaterialManager for flipping materials (needed for render to texture).

Yes, flipping I mean. Quote:There is also a switch in MaterialManager for flipping materials (needed for render to texture). I don't understand.

I don't have a sample at hand, but we will add something for the next release to explain what options are available.

Btw, this was implemented in v0.9.1, here is the unit test on how to do it: Code:
#region DrawMaterialFlipped
/// <summary>
/// This test explains how to draw materials vertically or horizontally
/// flipped. Internally the UVs are flipped, nothing else changes. You can
/// combine this with other operations like rotation or coloring as well.
/// </summary>
[Test]
public static void DrawMaterialFlipped()
{
Material2DColored logo = new Material2DColored("DeltaEngineLogo");
Application.Start(delegate
{
logo.Draw(Rectangle.FromCenter(
Point.Half + new Size(-0.5f, -0.5f) * logo.Size, logo.Size), 0,
FlipMode.None);
logo.Draw(Rectangle.FromCenter(
Point.Half + new Size(0.5f, -0.5f) * logo.Size, logo.Size), 0,
FlipMode.Horizontal);
logo.Draw(Rectangle.FromCenter(
Point.Half + new Size(-0.5f, 0.5f) * logo.Size, logo.Size), 0,
FlipMode.Vertical);
logo.Draw(Rectangle.FromCenter(
Point.Half + new Size(0.5f, 0.5f) * logo.Size, logo.Size), 0,
FlipMode.VerticalAndHorizontal);
});
}
#endregion
