Ogre HowTo——如何让摄像机不能穿透物体

 

void moveCamera()
...{ 
    mLastPosition=mCamera->getPosition();
    mCamera->yaw(mRotX);
    mCamera->pitch(mRotY);
    mCamera->moveRelative(mTranslateVector);

    //创建一个球体查询，这里的10是m_SphereNode挂着的那个球体的半径
    SphereSceneQuery* pQuery=mSceneMgr->createSphereQuery(Sphere(mCamera->getPosition(),10));
    //执行这个查询
    SceneQueryResult QResult=pQuery->execute();
    //遍历查询列表找出范围内的物体
    for (std::list<MovableObject*>::iterator iter = QResult.movables.begin(); iter != QResult.movables.end();++iter)
    ...{
        MovableObject* pObject=static_cast<MovableObject*>(*iter);
        if(pObject)
        ...{
            if(pObject->getMovableType()=="Entity")
            ...{
                mCamera->setPosition(mLastPosition);
                //if(ent->getName()=="Head")
                //{                    
                //    MessageBox(NULL,"a","df",MB_OK);
                //break;
                //}
            }
        }
   }
