Creating sounds for the player's bullets

Up until now, our game has been silent, but sound is an important factor in any game. In this section, we will be introducing our first sound component. We will make a start by creating sound effects for when our player fires a bullet.

Feel free to add your own type of bullet sound if you wish. You can add sound to your player's standard bullets as follows:

1. In the Unity editor, navigate to the Project window and create a new folder inside the Resources folder. Name the new folder Sound.
2. Drag and drop the Player_Bullet prefab from the Project panel into the Hierarchy panel.
3. With Player_Bullet still selected, click on the Add Component button in the Inspector panel.
4. In its dropdown, start typing (and select) Audio Source.
5. Drag and drop the PlayerLaser.mp3 file into the AudioClip section of the Audio Source component. The following screenshot shows Player_Bullet selected. The audio file at the bottom left needs to be dragged into the Audio Source component at the right:

1. Play on Awake is automatically ticked. As you can imagine, as soon as Player_Bullet is instantiated, the sound will play.
2. If the volume is too high, simply lower it in the Audio Source component of the Inspector window.

1. Finally, click on Apply at the top-right corner to save and update the Player_Bullet prefab and remove the bullet from the Hierarchy window.
2. Play the scene and start firing. You will hear laser noises and in the scene view, you will see speaker symbols now attached to the player's bullets.

That brings us to the end of this short section on audio, but we will cover more on audio throughout this book. Don't forget that if you get stuck at any point, check the Complete folder for this chapter and compare the scenes and code to make sure nothing is missing.
