捕鱼达人 中的闪电是通过一下步骤来实现的：

• 构建三角形条带
• 采用随机函数来扰乱条带顶点
• 快速反复循环一，二操作

这个过程主要使用以下三个类：

• VertexVector : 用于存储顶点和索引类
• Noise : 噪音处理类，用于进行顶点扰动，使顶点不断小幅变化
• LightLineRender : 实现闪电效果类

触屏时，一条闪电链击中屏幕中间的乌龟，乌龟被击中后翻了个身，闪电链渐渐消失：

//击中乌龟
void    FishLayer::AttackWuGui()
{
    if (m_Animation3D)
    {
        //从1.933秒到2.8秒截取为受伤的动作
        m_Hurt = Animate3D::create(m_Animation3D, 1.933f, 2.8f);
        m_Hurt->retain();
 
        m_Sprite->stopAllActions();
        //让精灵循环播放游泳和的受伤动作
        Sequence*   pSequence = Sequence::create(m_Hurt,CallFunc::create( std::bind(&FishLayer::ContinueSwim, this) ),NULL);
        m_Sprite->runAction(pSequence);
 
    }
 
}
//继续游动
void    FishLayer::ContinueSwim()
{
    if (m_Animation3D)
    {
        //从起始到1.933秒截取为游泳动作
        m_Swim = Animate3D::create(m_Animation3D, 0.f, 1.933f);
        m_Swim->retain();
 
        m_Sprite->stopAllActions();
        //让精灵循环播放游泳和的受伤动作
        Sequence*   pSequence = Sequence::create(m_Swim,NULL);
        m_Sprite->runAction(RepeatForever::create(pSequence));
    }
}
