Add Audio Effect into Parkour Game


In this tutorial, I want to show you how to add audio support into our Parkour game.

Time in Action

Audio Formats Supported by HTML5

At first, let's see which formats are supported by HTML5:

Here we use ogg format. Because it is well supported by Android and Chrome.

Add Audio Support into Our Game

Copy Audio Resources

At first, let's copy required audio files into our res directory. Audio files can be found in the sample project which can be downloaded from the Summary section.

We use background.ogg for background music, jump.ogg and pickup_coin.ogg for jumping and collecting the coins.

Secondly, let's define some global variables in the resource.js file:

var s_music_background = "res/background.ogg";
var s_music_jump = "res/jump.ogg";
var s_music_pickup_coin = "res/pickup_coin.ogg";
//add the following code line at the end of g_resource array

Add Audio Handling Code into The Game

At first, preload the audio files into our game. Add the following code snippets at the end of init function of myApp.js file:

//preload audio resources
var audioEngine = cc.AudioEngine.getInstance();

Secondly, add the background music when entering the PlayScene:

Note: Add the following code at the end of onEnter function in PlayScene.js.

//add background music
var audioEngine = cc.AudioEngine.getInstance();
audioEngine.playMusic(s_music_background, true);


When the game is over, we should stop the background music. So add the following code snippets in collosionRockBegin method:

 //stop bg music
var audioEngine = cc.AudioEngine.getInstance();

At last, let's add jumping audio effect and collecting coin audio effect.

//add the jumping audio effect in *jump* method of AnimationLayer
//stop bg music
var audioEngine = cc.AudioEngine.getInstance();
//add the collect coin audio effect in *collisionCoinBegin* method of PlayScene
 var audioEngine = cc.AudioEngine.getInstance();

Save all the changes and run the game. Now your game rock with a world full of audio.


In the tutorial, we have seen that how easy it is to add audio support into an existing game. You can download the whole project from here.

Where to go from here?

Now the journey of Parkour game has reached a milestone. In the following tutorials, we will add cross-platform support and do some encryption to our js files.

Keep tuning!
