Ogre播放动画

Ogre播放动画

ogre播放动画很简单，1、得到动画状态，2、设置enable为true,3、调用addtime

先来看代码：

class TutorialApplication : public BaseApplication{public:    TutorialApplication(void);    virtual ~TutorialApplication(void);protected:    virtual void createScene(void);virtual bool frameRenderingQueued(const Ogre::FrameEvent& evt);private:bool nextLocation();std::deque<Ogre::Vector3> mWalkList;Ogre::Real mDistance;Ogre::Real mWalkSpd;Ogre::Vector3 mDirection;Ogre::Vector3 mDestination;Ogre::AnimationState* mAnimationState;Ogre::Entity* mEntity;Ogre::SceneNode* mNode;};

//---------------------------------------------------------------------------TutorialApplication::TutorialApplication(void):mDistance(0),mWalkSpd(70.0),mDirection(Ogre::Vector3::ZERO),mDestination(Ogre::Vector3::ZERO),mAnimationState(0),mEntity(0),mNode(0){}//---------------------------------------------------------------------------TutorialApplication::~TutorialApplication(void){}//---------------------------------------------------------------------------void TutorialApplication::createScene(void){    // Create your scene here :)mSceneMgr->setAmbientLight(Ogre::ColourValue(1.0,1.0,1.0));mEntity = mSceneMgr->createEntity("robot.mesh");mNode = mSceneMgr->getRootSceneNode()->createChildSceneNode(Ogre::Vector3(0,0,25.0));mNode->attachObject(mEntity);mWalkList.push_back(Ogre::Vector3(550.0, 0, 50.0));mWalkList.push_back(Ogre::Vector3(-100.0, 0, -200.0));mWalkList.push_back(Ogre::Vector3(0, 0, 25.0));Ogre::Entity* ent;Ogre::SceneNode* node;ent = mSceneMgr->createEntity("knot.mesh");node = mSceneMgr->getRootSceneNode()->createChildSceneNode(Ogre::Vector3(0, -10.0, 25.0));node->attachObject(ent);node->setScale(0.1, 0.1, 0.1);ent = mSceneMgr->createEntity("knot.mesh");node = mSceneMgr->getRootSceneNode()->createChildSceneNode(Ogre::Vector3(550.0, -10.0, 50.0));node->attachObject(ent);node->setScale(0.1, 0.1, 0.1);ent = mSceneMgr->createEntity("knot.mesh");node = mSceneMgr->getRootSceneNode()->createChildSceneNode(Ogre::Vector3(-100.0, -10.0,-200.0));node->attachObject(ent);node->setScale(0.1, 0.1, 0.1);mCamera->setPosition(90.0, 280.0, 535.0);mCamera->pitch(Ogre::Degree(-30.0));mCamera->yaw(Ogre::Degree(-15.0));mAnimationState = mEntity->getAnimationState("Idle");mAnimationState->setLoop(true);mAnimationState->setEnabled(true);}bool TutorialApplication::frameRenderingQueued(const Ogre::FrameEvent& evt){if (mDirection == Ogre::Vector3::ZERO){if (nextLocation()){mAnimationState = mEntity->getAnimationState("Walk");mAnimationState->setLoop(true);mAnimationState->setEnabled(true);}}else{Ogre::Real move = mWalkSpd * evt.timeSinceLastFrame;mDistance -= move;if (mDistance <= 0.0){mNode->setPosition(mDestination);mDirection = Ogre::Vector3::ZERO;if (nextLocation()){Ogre::Vector3 src = mNode->getOrientation() * Ogre::Vector3::UNIT_X;if ((1.0 + src.dotProduct(mDirection)) < 0.0001){mNode->yaw(Ogre::Degree(180));}else{Ogre::Quaternion quat = src.getRotationTo(mDirection);mNode->rotate(quat);}}else{mAnimationState = mEntity->getAnimationState("Idle");mAnimationState->setLoop(true);mAnimationState->setEnabled(true);}}else{mNode->translate(move * mDirection);}}mAnimationState->addTime(evt.timeSinceLastFrame);return BaseApplication::frameRenderingQueued(evt);}bool TutorialApplication::nextLocation(){if (mWalkList.empty())return false;mDestination = mWalkList.front();mWalkList.pop_front();mDirection = mDestination - mNode->getPosition();mDistance = mDirection.normalise();return true;}

这里创建了一个机器人，然后让它走路。走完了之后，切换动画为idle.
