Cocos2d-X 3.4版-血条跟随怪物运动《赵云要格斗》

血条跟随怪物运动，当然非常容易想到的就是通过组合的方式将一个怪物精灵和

以前我们制作的ProgressView放在一起，然后通过就像他头像放在血量条旁边一样，

通过位置的一些计算让怪物们在头顶，顶上一个血量条。

类似的我对Monster的setAnimation，AttackAnimation进行了改写。

    // 14 frames * 1sec = 14 seconds
    m_MonsterSprite->runAction(act);
    IsAttack=true;
}

我只是对相关的几个函数进行了简单的重写。

代码如下：

Animation* getAnimation(const char *name_each,bool run_directon);
    void SetAnimation(const char *name_each,bool run_directon);
    void AttackAnimation(const char *name_each,bool run_directon);

Animation* Hero::getAnimation(const char *name_each,... */
    animation->setLoops(1);
    
    return animation;
}

void Hero::SetAnimation(const char *name_each,bool run_directon)
{
    if(HeroDirecton!=run_directon)
    {   HeroDirecton=run_directon;
        m_HeroSprite->setFlippedX(run_directon);
    }
//    if(IsRunning)
    if(IsRunning || IsAttack)
        return;
    auto ani = getAnimation(name_each,run_directon);
    auto action = Animate::create(ani);
    auto ccback = CallFunc::create(CC_CALLBACK_0(Hero::RunEnd,NULL);
    m_HeroSprite->runAction(act);
    
    IsRunning=true;
}

void Hero::AttackAnimation(const char *name_each,callfunc_selector(Hero::AttackEnd));
    auto ccback = CallFunc::create( CC_CALLBACK_0(Hero::AttackEnd,NULL);
    // 14 frames * 1sec = 14 seconds
    m_HeroSprite->runAction(act);
    IsAttack=true;
}
