Loading and Playing Sounds and Music


The implementation of the sound system in Panda3D allows for a division of audio into two categories - Sound Effects and Music. This division is only a convenience for programmers as Panda3D allows these two audio groups to be treated individually. These differences are explained on the next page.


Loading a Sound

Loading sound is done through the AudioManager class by supplying the path to the sound file as a parameter for get_sound(). Here’s an example:

PT(AudioManager) AM = AudioManager::create_AudioManager();
PT(AudioSound) mySound = AM->get_sound("path/to/sound_file.ogg") ;

These will return an object of the type AudioSound. It is necessary to put the extension in the sound filename.

Playing/Stopping a Sound

To play sounds you can do the following:


To stop a sound:


Querying Sound Status

To check the status of a sound, call status():


status() returns a constant depending on the status of the sound:




The sound is not working properly.


The sound is not currently playing and is ready to be played on command.


The sound is currently playing.

Example usage of this would be to stop a sound from playing only if it’s currently playing.

Setting Volume

The volume can be set between 0 and 1 and will linearly scale between these.


Panning a Sound

You can change the balance of a sound. The range is between -1.0 to 1.0. Hard left is -1.0 and hard right is 1.0.
