当第一个剪辑停止时，不能让第二个AudioClip开始

新手编码员

简单地说，当玩家点击屏幕上的按钮时，一个机器人就会被实例化，四处走动一会儿，然后播放"奔跑"的声音。一旦机器人电量耗尽，声音停止播放，并且一个新的"停止"声音应该播放。

除了最后一部分，其他都可以。一旦"running"的声音停止播放，我就无法让"stop"的声音播放。我在Update函数中处理这个逻辑。

private AudioSource 
    robotRun_big,
    robotStop_big;
private RobotMover robotMover;
// Omitted AddAudio() function that works fine.
void Awake()
{
    // Contains a variable I use as a timer
    robotMover = GetComponent<RobotMover>();
    // Declare and initialize an AudioClip
    AudioClip clipRobotRun_big = Resources.Load("SFX_19-23/robotRun_big") as AudioClip;
    // Initialize an AudioSource (declared as a private variable above)
    robotRun_big = AddAudio(clipRobotRun_big, true, false, 0.5f);
    // Same as above
    AudioClip clipRobotStop_big = Resources.Load("SFX_19-23/robotStop_big") as AudioClip;
    robotStop_big = AddAudio(clipRobotStop_big, false, false, 1.0f);
}
// This is handled elsewhere, but it determines which object player clicks
public void CheckGameObject(GameObject clicked)
{
    if(clicked.name == "RobotGrower")
        robotRun_big.Play(); // This works fine
}

void Update()
{
    if(robotMover.robotPower <= 0)
        robotRun_big.Stop(); // This works fine.
    if(!audio.isPlaying)
        robotStop_big.Play(); // This DOES NOT work fine.
}

我也试过这个:

if(robotMover.robotPower <= 0)
    robotRun_big.Stop();
    robotStop_big.Play();

:

if(robotMover.robotPower <= 0)
    robotRun_big.Stop();
    robotStopped = true;
if(robotStopped)
    robotStop_big.Play();

如果我从Awake或其他地方播放robotStop_big剪辑，则播放良好。只是在Update中没有那个逻辑。很明显，我漏掉了什么。任何帮助都是感激的。谢谢。

if(!audio.isPlaying)
    robotStop_big.Play();

if (!robotRun_big.isPlaying)
    robotStop_big.Play();
