Adding coins to level 2 & 3

Thanks. I downloaded the zip, and I was able to open the project. Solving the problem with the non-collectable coins took me a while but the fix was very simple: The player did not have the “Player” tag assigned in Level 2 and 3. I was looking at the assigned “Layer” and thought that was the tag until I logged the tag into the console. The console said “untagged” but the code needs:

if (other.tag == "Player" && !wasCollected)

Then I took a closer look at the Inspector and noticed my mistake.

However, I still cannot hear the sound when I collect a coin in level 2, even though the “One shot audio” game object appeared in the Hierarchy. When I disable the CinemachineBrain component on the Player, I am able to hear the sound. I did some research and found a thread by another student. For them, the fix was to set the “Update Method” of the CinemachineBrain to “Manual Update”.

Unfortunately, the camera will not move anymore with that setting.

I fixed that problem by moving the AudioListener to a non-moving game object: “Cameras”. I also added a new class: AudioListenerPosition.

The AudioListenerPosition simply returns the position of this component/game object. This is a more performant solution than calling FindObjectOfType whenever you want to play a sound clip.

using UnityEngine;

[RequireComponent(typeof(AudioListener))]
public class AudioListenerPosition : MonoBehaviour
{
    static AudioListenerPosition instance = null;
   
    void Start()
    {
        instance = this;
    }

    public static Vector3 GetPosition()
    {
        if (instance == null) { return Vector3.zero; }
        return instance.transform.position;
    }
}

And in the CoinPickup class:

Vector3 position = AudioListenerPosition.GetPosition();
AudioSource.PlayClipAtPoint(coinPickupSFX, position);

Did this fix it for you?
