一文详解Unity3D AudioSource组件使用示例

// 加载音频片段
AudioClip audioClip = (AudioClip) Resources.Load("Audio/Footstep01");
// 获取AudioSource组件
AudioSource audioSource = GetComponent<AudioSource>();
// 绑定音频片段
audioSource.clip = audioClip;
// 播放音频（选其中一种方式）
audioSource.Play();
// 此方式播放音频, Unity3D会在transform.position处创建一个空游戏对象, 播放完音频后自动销毁该游戏对象
AudioSource.PlayClipAtPoint(audioClip, transform.position);

using UnityEngine;
public class AudioController : MonoBehaviour {
	private PlayerController player;
	private AudioSource audioSource;
	private void Awake() {
		audioSource = GetComponent<AudioSource>();
		player = GameObject.Find("Player").GetComponent<PlayerController>();
	}
	private void Update() {
		if (player.isMoving) {
			PlayAudio();
		}
	}
	private void PlayAudio() {
		if (!audioSource.isPlaying) {
			audioSource.Play();
		}
	}
}

using UnityEngine;
public class PlayerController : MonoBehaviour {
	public bool isMoving = false;
	private void Update() {
		isMoving = Move();
	}
	private bool Move() {
		float hor = Input.GetAxis("Horizontal");
        float ver = Input.GetAxis("Vertical");
		if (Mathf.Abs(hor) > 0.1f || Mathf.Abs(ver) > 0.1f) {
			Vector3 dire = new Vector3(hor, 0, ver) * Time.deltaTime * 10;
			transform.position += dire;
			return true;
		}
		return false;
	}
