Feature requests / Make the class serializable.
« on: July 23, 2014, 06:51:59 pm »
It would be nice to make some SFML classes like sf::Vector, sf::Rect, sf::Color, sf::Vertex, sf::VertexArray, ..., serializable.
It's sometimes paintfull to send complex entities throught the network or to save them into a file. (Especially when entities have a lot of objects and vectors)
Ok this code is good but I have to change everything because SFML classes are not serializable so :
It'll not work because IntRect is not serializable.
For the texture it doesn't matter because I can't send the pointer to the texture directly, but, I send a string instead which tells me which texture to use.
I can make the sf::Texture class serializable and send the image throught the network but I don't thing that's a good idea.

ar & position.z;
ar & color.r;

ar & color.a;
ar & texCoords.x;
ar & texCoords.y;
