Learning 2D Game Development with Unity®: A Hands-On Guide to Game Creation

Our footstep audio is likely going to be the most commonly heard sound effect in the game. The constant repetition can wear on the player, causing listener fatigue. In order to help mitigate that, let’s create an array of footstep sound effects to draw from.

1. Open the PlayerController script. Make the changes shown in Listing 11.10.

public AudioClip[] footstepSounds;void PlayFootstepAudio(){  this.audioSource.clip = footstepSounds[(Random.Range(0,footstepSounds.Length))];  this.audioSource.Play();}

2. Select the Player GameObject.

3. Set the size of the Footstep Sounds array to 3.

4. Assign a different footstep sound to each field in the array.
