Flip sprite vertically AND horizontally?

Question

In Microsoft.Xna.Framework.Graphics.SpriteEffects there is the possibility to flip a texture horizontally or vertically before rendering. But can one do both at the same time?

When I use: spriteEffect = SpriteEffects.FlipHorizontally | SpriteEffects.FlipVertically; with spriteEffect being a parameter of the particle. The method spriteBatch.Draw(spriteSheet, currentPositionForDraw, sourceRectangle, currentColorMultiplied, currentRotation, currentOriginForDraw, Temp.delta, spriteEffect, 0); does not draw the particle flipped on both axis.

Answer 1

Yes. If you look at the definition of that enum you'll see it has [FlagsAttribute] which means you can combine the enum values with the | operator.

Answer 2

If you don't care about rotation, you can simply set the origin of the sprite to its center and rotate it 180 degrees (Math.PI). This is the same as flipping horizontally and vertically.

If you do care about rotation, and the sprite is flipped both ways, you can just add Math.PI to the angle and you should be done (eg. 45 degrees + 180 degrees rotation looks the same as 45-degrees flipped on both axes).
