custom class serialization problem

Questions & Answers
1

I made a class like this

[System.Serializable]
public class AudioClipPlayer : Object
{
    private AudioClip clip;
    private float repeat;
};

and on the Inspector, it appears like this

-----------------------------------------------------
Audio Clip Player          None (Audio Clip Player) @
-----------------------------------------------------

Here's the problem I want to drag and drop a audio file to the 'None' area. But I have no idea what I have to do. I want to look like this

----------------------------------------------
Audio Clip Player          None (Audio Clip) @
----------------------------------------------

And I want to look exactly like above.. because I wanna make a array for AudioClipPlayer like this 

[System.Serializable]
public class ZombiAudioClips
{
    public AudioClipPlayer[] idleClips;
}

I want to make that Unity recognize AudioClipPlayer to AudioClip. Is that possible? Thx for reading.

Remove the : Object for a start, it'll be making your class inherit UnityEngine.Object which makes very little sense. After that, you'll want to either make the fields public, or add [SerializeField] above both of them

[System.Serializable]
public class AudioClipPlayer
{

    public AudioClip clip;
    public float repeat;
};

or

[System.Serializable]
public class AudioClipPlayer
{
    [SerializeField]
    private AudioClip clip;
    [SerializeField]
    private float repeat; //note, these aren't going to be accessible from outside the class
};
