【问题描述】:
我在使用 Visual Studio 2013 时遇到问题。我无法解释为什么会这样。编译问题如下图所示。
我有一个使用“RigidBody.cpp/h”类的“PhysicsEngine.cpp/h”类就好了。一旦我尝试在我的 Character 类标头中使用 RigidBody 类,它就无法看到 RigidBody 类标识符。我已经在我的文件中包含了“RigidBody.h”,甚至尝试对这个类进行原型设计。有趣的是,当我删除“RigidBody.h”标题包含时,它会吐出更多错误,让我相信它正在阅读它。是不是我做错了什么?
这是我收到的错误输出:
1>------ Rebuild All started: Project: SideScroller, Configuration: Debug Win32 ------
1> WorldChunkManager.cpp
1> World.cpp
1> Vector.cpp
1>e:(directory)\vector.cpp(41): warning C4244: 'argument' : conversion from 'double' to 'float', possible loss of data

1>e:(directory)\character.h(21): error C2143: syntax error : missing ';' before '='
1>e:(directory)\character.h(21): error C2238: unexpected token(s) preceding ';'
这是 RigidBody.h 的代码
#ifndef RH
#define RH
#include "Vector.h"
#include "World.h"
#include <cmath>
#include <list>
class RigidBody
{
private:
int id;
float gravityFactor;
float airResistFactor;
float mass;
float elasticity;
Vector pos = Vector(0, 0);
int width;
int height;
Vector velocity = Vector(0, 0);
std::list<Vector>* additiveVelocities;
std::list<Vector>* forces;
public:
RigidBody(int x, int y, int w, int h, float mass, float elasticity, float gravityFactor, float airResistFactor);
~RigidBody();
static int rigidBodyCount;
//Get/Set
int getID();
double getX();
double getY();
float getGravFact();
float getAirFact();
float getMass();
float getElast();
Vector getPos();
Vector getVelocity();
std::list<Vector>* getadditiveVelocities();
std::list<Vector>* getForces();
void setX(double x);
void setY(double y);
void setVelocity(Vector& vec);
void setPos(Vector& vec);
//Interactino Functions
void addForce(Vector force);
void addVelocity(Vector velocity);
};
#endif
这是不起作用的代码(Character.h):
#ifndef CHARACTER_H
#define CHARACTER_H
#include "SDL.h"
#include "Camera.h"
#include "InputManager.h"
#include "Vector.h"
#include "RigidBody.h"
//TEMP DIM
const int CHAR_H = 64;
const int CHAR_W = 12;
class Character
{
private:
double speed;
//Vector pos = Vector(0, 0);
RigidBody pos = RigidBody(0, 0, CHAR_W, CHAR_H, 50, 0, 1, 1);
InputManager* inputPtr;
public:
Character(int x, int y, InputManager* inputPtr);
void getXY(int* dest);
void getChXY(int* dest);
void getCenterXY(int* dest);
//Update
void update(long double last);
bool isFloor();
//Draw
void draw(SDL_Surface* screen, Camera* camPtr);
};
#endif
