对于可怜的问题标题表示歉意,我不确定该怎么问。尝试编译我的GLUT游戏时出现LNK2019错误,我无法发现导致错误的原因。

错误:
main.obj:error LNK2019: unresolved external symbol "public: void __thiscall asteroid::animateAsteroid(void)" (?animateAsteroid@asteroid@@QAEXXZ) referenced in function "void __cdecl idle(void)" (?idle@@YAXXZ)

小行星

class asteroid
{
public:
asteroid(void); //constructer
~asteroid(void); //deconstructer

void Draw();
void createAsteroid();
float generateAsteroidLocation(float a, float b);
void animateAsteroid();
};


asteroid.cpp(故障功能)

#include "asteroid.h"
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#define _USE_MATH_DEFINES
#include <math.h>
#include <ctime>
#include <GL/glut.h>

float asteroidX,asteroidY, V;
bool locationGenerated = false;

asteroid::asteroid(void){

}

asteroid::~asteroid(void){

}
void animateAsteroid(){
float dt = 3500;
float Dx = 25 - asteroidX;
float Dy = 25 - asteroidY;
float Cx = asteroidX + Dx / sqrt(Dx*Dx+Dy*Dy) * V * dt;
float Cy = asteroidY + Dy / sqrt(Dx*Dx+Dy*Dy) * V * dt;
asteroidX = Cx;
asteroidY = Cy;
}


Main.cpp(出现错误的函数)

void idle(void)
{
glutPostWindowRedisplay(glutGetWindow());
Asteroid.animateAsteroid();
}


对于解决此问题的任何帮助,我将不胜感激。

谢谢,丹。

最佳答案

在asteroid.cpp文件中,方法声明中缺少类名:

void asteroid::animateAsteroid(){
...
