Graphics / Re: Deleting image and using one sprite for displaying all images in the program

Wow, this code is really useless. Well, i guess using new and delete gives me illusion of more control on what program actually does  . Anyways, thanks for help, looks like it's time to move on.

Graphics / Deleting image and using one sprite for displaying all images in the program

« on: July 21, 2012, 08:47:43 pm »

Hi. I started using SFML (version is 1.6) and found that there is no Release-like function for SFML resources (like in SDL). I know, that resources in SFML are freed as soon as they go out of scope, but i need to be able to load and delete images when and where i want. So i decided to make this class

class texture
{
private:
        sf::Image image;
public:
        texture(char* destination)
        {
                  image.LoadFromFile(destination);
        };
        ~texture()
        {
                  //do nothing
        }
        sf::Image* get_pImage()
        {
                  return ℑ
        }
};
 

to be able to locate and free memory using new and delete on texture objects (yeah, i know, this is awful).
The sprite correctly draws on the screen, but when i try to draw it after deleting texture it shows only a white rectangle of image size. So the question is: is image actually deleting when i use delete, or it just screws up connection with sprite?
And the second question: can i use one sprite to display all images on the screen (like when using directx) or it will cause low performance?
