With SFML 1 you can't. However you can copy an image to another.

Why do you want to do that?

I forgot the reason! But with SFML 1.6 this code doesn't work.

Ok I got it, what I mean is: if you don't know why you're asking, then who cares about the answer? Why are we having this discussion? It's hard to solve a problem that doesn't exist.

Ok but I can't give you an alternative because none of us knows what you want to do...

I got it.
I am going to do a game with aircraft. And you can tune up your plane during in the game, so the plane has to consist of parts. This is that situation. You draw parts to one sprite and then draw always this sprite to one position, instead of drawing many parts to many positions. So so what you recommend me?  :roll:   :?

That is more an design issue. Though just thinking quick I would use relative positions and use the conversion methods to transform them to world coordinates. This way we can draw the sprites seperatly.

But I think it is not so good like draw it one time to one sprite and then draw always it like one picture.

then have it like one image? If you want it to be static you don't need it in separate parts. If you want the sprites to change over time or when something happens then you are forced to do like I said.

What you more or less wants/describes are creating an image at runtime(which is available in SFML2). But since it's for a game you can simply have the image already premade with all the separate parts in it.

Though if you like I said, want the parts to change, like position, size, image and so on then you have to do it like I said or something similar. Here "drawing a sprite to a sprite" would only mean that every time we change the object's state in a way that the parts are affected we would have to do everything again.

Thanks I wanted exactly this which is availaible in SFML 2, so I will wait for a little while :D, so I can draw a sprite to another sprite in SFML2

There's no need to wait to use SFML2, I'm using it in a game right now and it works fine.

Code: [Select]
sf::RenderImage image;
image.Create( /* look in the documentation for values */ );
image.Draw(theFirstSprite);
image.Draw(theSecondSprite);
image.Draw(theThirdSprite);
image.Display();

sf::Sprite wholeSprite(image.GetImage());
window.Draw(wholeSprite);


Though I think you don't actually understand what you actually want to do. For in-game graphics, the sprites will change so often that you will recreate the sprite every frame.
