General / Re: when do i dynamicaly allocate my variables/array

« on: May 08, 2013, 12:01:37 pm »

would this be the correct way to use c++/sfml in order to avoid memory leaks?:

 // Load a sprite to display
    sf::Texture texture;
    if (!texture.loadFromFile(resourcePath() + "cute_image.jpg")) {
        return EXIT_FAILURE;
    }
    sf::Sprite sprite(texture);

    //use my sprite in the game...
   
    sprite.~Sprite();
    texture.~Texture();

General / when do i dynamicaly allocate my variables/array

« on: May 07, 2013, 11:05:56 pm »

i'm still new to c++ but i've been reading about it :-)

in the simple example when i run the sfml template fromxcode it creates a sound, a background image and a text in the upper right corner
sf:texture texture allocate a place for my texture?
but it is not dynamically - meaning i can't free the memory? Right?
If i want to do level1 and level 2 everything  concerning level 1 should be dynamicaly allocated so that i can free the memory for level2 - right?

I've always had a garbage collector to clean my programs, so I have to ask these simple questions :-)

Thanks a lot for your help. I can't wait to write 'yet-another-space-invaders' using SFML.
Regards Eric

I've ordered som c++ books and while I wait I follow this 'course': http://www.learncpp.com

I strongly recommend this page if other wants to learn c++ without a book!

Congratulations with the release of 2.0! I just managed to get the old 2.0 installed on my Xcode a week ago :-) I  find it very interesting

I'm an experienced java-programmer and I've heard a lot about memory leaks, pointers and other warnings about c++ in the past - but I really like SFML and want to try it out

I have a question regarding the C++ language. I know there is no garbage collector in c++, but should I worry about destroying objects / smart pointers and stuff in C++? I'm new to c++ but syntax seems very familiar and I want to learn that language.
