自制简单的3D音效播放脚本
使用如下
新建场景,
新建空对象,挂载测试脚本testEasyAudio_3D
public class TestEasyAudio_3D : MonoBehaviour{AudioListener audioListener;GameObject leftAudio, rightAudio;private void Awake(){audioListener = FindObjectOfType<AudioListener>();if (audioListener){print("find listener");}leftAudio = new GameObject();leftAudio.transform.position = audioListener.transform.position + new Vector3(-15, 0, 0);rightAudio = new GameObject();leftAudio.transform.position = audioListener.transform.position + new Vector3(15, 0, 0);}private void Update(){if (Input .GetKeyDown (KeyCode.A)){EasyAudio_3D.PlayAudio_3D("testAudio", leftAudio);}if (Input.GetKeyDown(KeyCode.D)){EasyAudio_3D.PlayAudio_3D("testAudio", rightAudio);}}}
上代码
