模型动画：简单人物动画
实现简单的人物动画：
1、 设置动画状态：AnimationState
Ogre::AnimationState* _aniState;
2、 获取模型实体的动画效果：getAnimationState
_aniState = mEntity->getAnimationState(“Dance”);//以Sinbad模型为例，其含有Dance动作,mEntity为Entity类型
3、 动画效果开启：setEnabled
_aniState->setEnabled(true);//开启
//也可添加动作循环执行
_aniState->setLoop(true);
4、 添加动画执行时间：addTime
在frameStarted()中添加事件：_aniState->addTime(evt.timeSinceLastFrame);
动画的运动时间：evt.timeSinceLastFrame是指自上一帧到现在过去的时间，如果我们将其*0.1，则表示动画运动的时间变少，其会放慢执行，即实现了慢动作。
