代码如下：

using UnityEngine;
 
/// <summary>
/// 眨眼类
/// </summary>
public class EyeBlink
{
    static float[] Weights = new float[] { , , , ,  };     // 100时眼睛全闭，0时眼睛全开
 
    public SkinnedMeshRenderer Face;
    bool m_enable = true;
 
    bool m_blinking;
    float m_timer;
    int m_index;
 
    public void Update()
    {
        if (!Face || !Enable)
            return;
 
        m_timer -= Time.deltaTime;
 
        if (m_blinking)
        {
            if (m_timer < )
            {
                m_timer = 0.05f;                    // 每隔0.05s设置一次眨眼动画，可调节眨眼的快慢
                m_index++;
 
                if (m_index < Weights.Length)
                    SetShape(m_index);              // 设置眨眼动画，从闭到开
                else
                {

                    m_timer = Random.Range(, );   // 设置眼睛保持睁开的时间
                }
            }
        }
        else
        {
            if (m_timer < )
                ToBlink();                          // 开始眨眼

    }
