Title: struct + sf::Music + malloc = error (?)
Post by: virus on September 11, 2010, 12:27:03 am

Hello!

I am trying to have sf::Music into a dynamic list (struct below):

typedef struct sound{
    sf::Music audio;
    char *name;
    struct sound *next;
}sound;

When I declare:

sound test;
test.audio.OpenFromFile("music.ogg");
test.audio.Play();

it works.

But when I do:

sound *test;
test = (sound*)malloc(sizeof(sound));
test->audio.OpenFromFile("music.ogg");
test->audio.Play();

It doesn't work.

(I know, I am no treating the char stuff, but i just didn't post it here...)

Why doesn't it work?

When using C++ you shouldn't use malloc, use new instead.

Code: [Select]

sound *test;
test = new sound;

Such an easy solution!

What about playing the same music 2 times at almost the same time without stopping the first?

I mean, i am playing a music, and then I want it to start again, without stopping the first music to play, so it starts again and the same music is playing in 2 different positions.

How can I do that?

There is no other way? It is too slow and heavy.

Afterall, i cannot know how many times will i have to play the same song simultaneously :/

I think that sf::Music is one of the most light-weight class in the SFML library
