2.2.5 Cycle 5 - Adding Sound

Design

Objectives

In this cycle I aim to add different sounds to different things I may implement into the game such as picking up health or the enemy being destroyed. I will also add a background track to the game so that the game is more emersive and fun.

• Add sounds for different things that happen in game

• Add a background track

Usability Features

Key Variables

    play(backgroundSoundTrack) at 50% vol
end procedure

Outcome

Game.js

Game.js

preload(){
  ...
  game.load.audio('laserBlast', 'assets/laserNoise.wav');
  game.load.audio('enemySplode', 'assets/enemyExplode.wav');
  game.load.audio('healthGet', 'assets/healthSound.wav');
  game.load.audio('playerDie', 'assets/playerDie.wav');
  game.load.audio('gamePlay', 'assets/GamePlaySoundTrack.mp3');
}

create(){
    ...
    backgroundSoundTrack = game.sound.add('gamePlay');
    backgroundSoundTrack.play();
    backgroundSoundTrack.loopFull();
    backgroundSoundTrack.volume = 0.5;
    ...
}

Challenges

In this cycle there were no issues at all with adding and playing songs or sound.

Testing

In my testing I used the webpack software to keep making small changes to the speed constant to be able to find a speed that I thought would be slow enough for the player to react to it and yet fast enough for it to be challenging to hit.

Tests

Test	Instructions	What I expect	What actually happened	Pass/Fail
Background music	Simply load into the game.	Music begins as soon as the game starts	As expected	Pass
