错误C2819:键入‘机器人：：动画’没有重载成员‘操作符’->‘

Question

我根本找不到这是为什么扔错了！好的，我有一个结构，里面有一些物体。然后创建指向该结构的指针，并逐一设置项。我一直在犯错误。下面是代码：

Robot.h:

// Name and Animation info
std::map<std::string, Ogre::AnimationState*> mAnims2;

struct Animation {
    std::string name;   // The name of the animation state
    Ogre::AnimationState* mAnimState;   // The actual animation state
    bool FADE_IN;       // Fade the animation in
    bool FADE_OUT;      // Fade the animation out
};

Robot.cpp:

    // Go through the set by using iterator
while (animStateIter.hasMoreElements()) {
    // The Animation object we will construct
    Animation* mAnimation = new Animation();
    // Initial values for Fading In and Out
    mAnimation->FADE_IN = false;    
    mAnimation->FADE_OUT = false;   
    // Create the Animation object, using the next animation in the list
    mAnimation->mAnimState = animStateIter.getNext();
    // Set the animations name
    mAnimation->name = Animation->mAnimState->getAnimationName();
    // Make sure the animation is set to Loop
    mAnimation->mAnimState->setLoop( true );
    // Insert the Animation object into the list of Animations
    mAnims2.insert( std::make_pair( mAnimation->name, mAnimation) );
    /* DEBUG */
    output << mAnimation->name << std::endl;
}

错误：

Error 1 error C2819: type 'Robot::Animation' does not have an overloaded member 'operator ->' c:\users\masry\school-work\fall-2010\cs-425\homework-4\gameengine_solution\robot.cpp 52

另外，如果您注意到，我正在尝试动态创建Struct对象并将它们插入Map中。我呼吁：

Animation* mAnimation = new Animation();

在一段时间的循环中，这是好的OO设计吗？如果没有，有什么更好的方法呢？谢谢。

编辑：所以，多亏了Frédéric，原来我漏掉了一封信。但现在我听到一个错误：

Error   17  error C2784: 'std::basic_ostream<char,_Traits> &std::operator <<(std::basic_ostream<char,_Traits> &,unsigned char)' : could not deduce template argument for 'std::basic_ostream<char,_Traits> &' from 'std::string'    c:\users\masry\school-work\fall-2010\cs-425\homework-4\gameengine_solution\robot.cpp    58

Answer 1

我认为你的错误在于：

// Set the animations name
mAnimation->name = Animation->mAnimState->getAnimationName();

这可能应该是：

// Set the animations name
mAnimation->name = mAnimation->mAnimState->getAnimationName();
