Title: Sfml 2.0 Flipping a sprite
Post by: ayzed on April 12, 2012, 04:52:06 am

Is there a way to flip a sprite as easy as FlipX() in sfml 1.6 ???

Sprite.Scale(-1.f,1.f); is the simplest way as far as I know

You can set the origin of the sprite to its center (half-size).

somthing else, why animations from sprites are buggy and sometimes the images disappear?

Because there are errors in your code?

Hey Laurent,

I found the flip function in SFML 1.6 quite handy; and while this solution works for 2.0, it seems a bit less elegant than the previous method.

Is there any chance that you'd be adding back the flip methods to SFML 2.0 ?

Nop. Note that there's a better solution: using a textureRect with negative width/height (this solution maps exactly to what the Flip functions did).

// flip X
sprite.setTextureRect(sf::IntRect(width, 0, -width, height));

If you really miss the Flip functions, you can write yours as free functions, using the implementation above.

When I use this I can only flip it once?

What do you mean once?

// flip X
sprite.setTextureRect(sf::IntRect(width, 0, -width, height));

// unflip X
sprite.setTextureRect(sf::IntRect(0, 0, width, height));

I did not find the correct values for unflipping it.So thank you for helping me  :)

The correct values are the values you use to draw the sprite normally, simply. :p
