    My guess is that LoadTexture has a related function to "delete" a texture in some way - exactly what it is called should be part of the documentation for the library you are using. This is what you should called to "destroy" the texture - note that there may well be other resources tied to a texture, such as a "texture object" in the graphics library or graphics driver, so there's further reasons to destroy it properly.

    What is the array method?

    delete[]

    free()?

    Mind giving us the link to the documentation?

    Something weird most be happening. I can use the class functions in the Sprite class that I have created before, but if i try to add a new one, i get an error (same as before)
    Code:
    If I add 
    void Sprite::foo()
    {
    // Do noting
    }
    
    and call it:
    spriteList[0]->foo();
    
    I get an error.
    But if I use one of the older functions, it works fine

    Maybe your sprite isn't allocating memory correctly?

    Im sorry, but I cant post a link to the documentation, but it says that caller of the loadTexture function has to delete the returned data them self. And that it should be deleted using the array method.

    Also, there is no deleteTexture function or something like that.

    I think it does, as I can draw to the texture without any problems. Its just deleting it that is hard.

    EDIT:
    What might be a reason for non of my new functions working? Like the foo() example

    You'd have to post a complete, compilable example of what is going wrong - although the likely scenario is that you end up finding it yourself if you try to create this - but it's hard to guess what goes on in "..." that you haven't posted, and I suspect:
    1. You are not too keen on posting it.
    2. I'm certainly not keen on reading loads of code to find what's wrong.

    I cant post my entire code or the needed libraries needed to compile it due to copy rights. I tried to take as much out as possible, and I can use new functions now, but I still get the memory loss even though I call the destructor for the sprites when the program closes.

    Sorry for not posting the needed files, but thanks a lot for the help

    I think the correct thing to do is to call "delete [] spritedata" - but I'm not 100% sure.

    Reworked the whole thing and removed a pointer that casued me nothing but trouble.

    matsp: Your right, its delte[]

    Its working now, with no memory leaks.

    Thanks a lot to matsp and sethjackson!
