Game Development How to Make a Video Game Game Audio Play Sounds with Scripts

My frog and bird aren't playing sound, all others are. Someone know why?

Here is my RandomSoundPlayer code:

using UnityEngine; using System.Collections; using System.Collections.Generic;

public class RandomSoundPlayer : MonoBehaviour {

private AudioSource audioSource;
[SerializeField]
private List<AudioClip> soundClips = new List<AudioClip> ();
[SerializeField]
private float soundTimerDelay = 3f;
private float soundTimer;

// Use this for initialization
void Start () {
    audioSource = GetComponent<AudioSource> ();

}


void FixedUpdate () {
    soundTimer = soundTimer * Time.deltaTime;

    if(soundTimer >= soundTimerDelay) {
        soundTimer = 0f;

        AudioClip randomSound = soundClips[Random.Range (0, soundClips.Count - 1)];

        audioSource.PlayOneShot (randomSound);
    }
}

}

I create the Audio Source, did all the configuration in Unity but my frog and bird still don't make any sound. Bird Calls, Bird Footsteps and Player Footsteps aren't working. Did I miss something?

Hi Mario

You have set the soundTimer to soundTimer multiplied (*) by Time.deltaTime which because soundTimer is 0 at the start always equates to zero. simply change this to 

soundTimer = soundTimer + Time.deltaTime;

Hope this helps Daniel

Thanks Daniel! You're got it! I didn't notice that I was multiplying Time.delta by 0 always.
