音频

AudioSource audioSource;

void Start()
{
    rigidbody2d = GetComponent<Rigidbody2D>();
    animator = GetComponent<Animator>();
    currentHealth = maxHealth;

    audioSource= GetComponent<AudioSource>();
}

public void PlaySound(AudioClip clip)
{
    audioSource.PlayOneShot(clip);
}

public class HealthCollectible : MonoBehaviour
{
    public AudioClip collectedClip;
    
    void OnTriggerEnter2D(Collider2D other)
    {
        RubyController controller = other.GetComponent<RubyController>();

        if (controller != null)
        {
if (controller.health < controller.maxHealth)
            {
            	controller.ChangeHealth(1);
            	Destroy(gameObject);
            
            	controller.PlaySound(collectedClip);
}
        }

    }
}

• 就像我们在上面的 HealthCollectible 中所做的那样，将公共的 AudioClip 成员添加到 RubyController 脚本中以存储投掷声音或击中音频剪辑。
• 在 RubyController 脚本中的合适代码位置，在音频源上调用 PlayOneShot。
