Level Music

[unrealfragmaster]

I have used the Collision tutorial to load my own level in with collision detection. What code do I have to add in and where do i have to add it to let the level have background music, a file called back.mp3?

[wornaki]

Try looking at the techdemo sourcecode. It uses audiere and works pretty well

I have been looking at it, but I dont really undertsand, as it uses lots more things like the Ball sound and explosions. I just want a simple piece of code I can use to put level music into the Collisions demo, then bit by bit work up to being able to make the tech demo.

You would need to add in Audiere, fmod, or any of the numerous sound libraries.

Irrlicht itself does not do sound.

I know i have to use Audiere. Im posting in Beginner forum because I dont know HOW to use it. I need someone to show me what code to add into the collision example to call audiere and play music.

Just take a look at the audiere documentation. I think you would have needed only about 1-2 minutes to get the code. But anyway, here it is:

Code: Select all

AudioDevicePtr audiereDevice;
OutputStreamPtr stream;

audiereDevice = OpenDevice();
stream = OpenSound(audiereDevice.get(), "back.mp3", true);
	
stream->setRepeat(true);
stream->play();

I have looked at the documentation, Ive examined the tech demo code, but I dont know where abouts in the code you put that. Do I just stick it at the very top? The bottom?

[unrealfragmaster]

Ah rite I didnt realise you had to download audiere separetely. Ive got the header file and all the other files now. Though I still dont know where abouts to add the coe. When I just add it in, I got a pile of errors.

[unrealfragmaster]

OK this is the Audiere code the documentation gives and Niko gave:

Code: Select all

AudioDevicePtr audiereDevice; 
OutputStreamPtr stream; 

audiereDevice = OpenDevice(); 
stream = OpenSound(audiereDevice.get(), "back.mp3", true); 
    
stream->setRepeat(true); 
stream->play(); 

This is the collision demo, where abouts do I add the above code to get a music file to play?

Code: Select all

Right after this line would work:

Code: Select all

int main() 
{

Thanks, it works

It wasnt working with me because I forgot about using the pragma statement
