基类的类型不完整
这个错误到底是什么意思，我该如何解决？我已经尝试通过class Entity在我的 EntityPhysics 标头中声明该类，但它不起作用。
这是我的 Entity.h
#ifndef __Game__Entity__
#define __Game__Entity__
#include <iostream>
#include <string>
#include "OGRE/Ogre.h"
#include "OgreInit.h"
class Entity{
public:
Entity(std::string entityId, std::string mesh, Ogre::Vector3 position = Ogre::Vector3::ZERO, Ogre::Vector3 rotation = Ogre::Vector3::ZERO);
virtual ~Entity() = 0;
void setPosition(Ogre::Vector3 position);
Ogre::Vector3 getPosition();
void setRotation(Ogre::Vector3 rotationIncrease);
Ogre::Vector3 getRotation();
void setMesh(std::string meshName);
std::string getMesh();
virtual void tick() = 0;
void removeEntity();
Ogre::Entity getEntity();
Ogre::SceneNode getSceneNode();
std::string entityId;
protected:
Ogre::Entity *ent;
Ogre::SceneNode *nod;
};
#endif /* defined(__Game__Entity__) */
还有我的 EntityPhysics.h
#ifndef __Game__EntityPhysics__
#define __Game__EntityPhysics__
#include <iostream>
#include <string>
#include "OGRE/Ogre.h"
#include "OgreBulletCollisionsBoxShape.h"
#include "OgreBulletDynamicsRigidBody.h"
#include "Entity.h"
#include "OgreInit.h"
class EntityPhysics: public Entity //error occurs here: "Base class has incomplete type"
{
public:
EntityPhysics(std::string pentityId, std::string mesh, Ogre::Vector3 position, Ogre::Vector3 rotation, /*Physics Specific "stuff"*/std::string shapeForm = "BoxShape", float friction = 1.0, float restitution = 0.0, float mass = 1.0);
virtual ~EntityPhysics() = 0;
virtual void tick() = 0;
private:
float friction, restitution, mass;
OgreBulletCollisions::CollisionShape *collisionShape;
OgreBulletDynamics::RigidBody *rigidBody;
};
#endif /* defined(__Game__EntityPhysics__) */
我认为这可能与我有关，包括Entity.h在子类中，但如果我这样做，我会得到同样的错误。
