Multiple sprite-rotation

[kafkadaffi]

Hi I was wondering if there is any possible way of doing  the following...

Imagine that I have an object, that has a render method and that method
renders a matrix/grid of sprites. eg. 10 times 10 sprites.
Is it possible to rotate that grid in whole. I have tried to rotate each individual sprite with a proper offset and that just looks bananas.

I guess I would like to render the sprites to another sprite and then rotate that grouping sprite, but that is not possible. Is there any other way of doing this?

Just put your grid of sprites into a class that inherits from sf::Drawable. Then all the transformations of this drawable will be combined with the sprites' ones.

Are you sure? I must have done something wrong.

I have setup an Object that inherits from sf::Drawable and then I override the Render() method, where I render say two different sprites. Sofar sogood, I see the sprites being rendered ok.

But transformation on that Object containing those sprites does exactly nothing to my contained sprites. I have hard time to think how it can ever.

Ah, my Bad!
I called Render of the compositing sprite with the target as parameter instead of calling Draw(&Drawable ) passing a reference to the compositing sprite. Clearly there is a difference.

Code: [Select]

m_tSprite.Render(*m_pMainWindow);  // Renders without parent obj. Translations and etc.
m_pMainWindow->Draw(m_tSprite);    // Renders using translations and etc.


Now it works like a clockwork!   :lol:

Come to think of it, It was fully possible to override the protected virtual Render( ) with a public one exposing the method.
