unity报错：MissingComponentException: There is no 'AudioSource' attached to the "1Button" game object, but a script is trying to access it.

这个错误提示说明在 ButtonController.cs 脚本的第31行，尝试访问 "1Button" 游戏对象上的 AudioSource 组件，但是该游戏对象上并没有 AudioSource 组件。解决方法有以下两种：

1. 在 "1Button" 游戏对象上添加 AudioSource 组件。在 Unity 编辑器中，选中 "1Button" 游戏对象，然后点击菜单栏上的 Component -> Audio -> AudioSource，添加一个 AudioSource 组件。

2. 在脚本中添加检查语句，确保在访问 AudioSource 组件之前，它已经存在于游戏对象上。在 ButtonController.cs 脚本中，可以在第31行代码之前添加以下代码：

if (!GetComponent<AudioSource>())
{
    Debug.LogError("There is no AudioSource component attached to this game object!");
    return;
}

这段代码会检查当前脚本所在的游戏对象上是否存在 AudioSource 组件。如果不存在，则会输出一条错误信息，并且退出 OnButtonClick() 函数的执行。

unity报错：MissingComponentException: There is no 'AudioSource' attached to the "GameObject" game object, but a script is trying to access it. You probably need to add a AudioSource to the game object "GameObject". Or your script needs to check if the component is attached before using it. DynamicPlayAudio.Start () (at Assets/EasyAR/Resources/Scripts/DynamicPlayAudio.cs:13)

这个错误是因为你的脚本在试图访问一个名为"GameObject"的游戏对象上的AudioSource组件，但是该游戏对象上并没有附加AudioSource组件。你需要在该游戏对象上添加一个AudioSource组件，或者在使用该组件之前，先检查该游戏对象是否已经添加了该组件。你可以在脚本的第13行检查是否存在AudioSource组件，如果不存在，可以添加代码来添加该组件，如下所示：

AudioSource audioSource = gameObject.GetComponent<AudioSource>();
if(audioSource == null){
    audioSource = gameObject.AddComponent<AudioSource>();
}

这样就可以避免这个错误了。
