Issues with sf::rendertexture
« on: October 19, 2015, 09:40:39 pm »
Hey guys i've been having some issues getting a rendertexture to work correctly. Well it might not be the render texture itself but my code surrounding it. here's the stack overflow link to my question i would greatly appreciate any help.

I attempt to make a copy inside a map of textures. at least i thought i did, is it possible that it's only passing by reference?

If you could link me to an article that explains it that would be great as well. I would love the opportunity to learn more about the explanation than just a simple answer =P

And we'd love to have a clear question, to avoid pointless guessing. If people still don't know what you mean after 6 posts, it's a good indicator that you should state your question differently ;)

Please read this post, and please do so carefully. It takes some time, but it will help you get better help in the future. And it certainly takes less time than waiting so long for answers :)

Sorry for not clarifying well enough. I'm just not sure how to go about getting a copy of a texture that i've made within a rendertexture. not just a reference to the rendertexture

sf::Texture tex = rt.getTexture();

Keep in mind that copying textures is slow.

I tried doing that. so it must be that i'm trying to copy a blank rendertexture because when i try and draw it to a window it doesn't even create a blank square.

I think I was wrong, I'm really sorry. :(
But I think the size of the rectangle shapes you are drawing is 0, 0.
