こんにちは私はクラスの初心者です、そして私はちょうどそれらを学び始めました。このエラーが発生する理由がわからないため、このコードについてサポートが必要です。
これが私のコードです
main.cpp
#include "stdafx.h"
#include "player.h"
SDL_Surface* screen = NULL;
void init()
{
SDL_Init( SDL_INIT_VIDEO );
//Set up screen
screen = SDL_SetVideoMode( 640, 480, 32, SDL_DOUBLEBUF |SDL_HWSURFACE |SDL_SWSURFACE);
//SDL_BlitSurface( hello, NULL, screen, NULL );
_putenv("SDL_VIDEO_CENTERED=1"); // Center the window
SDL_Init(SDL_INIT_VIDEO);
SDL_WM_SetCaption("SDL Animation", "SDL Animation");
//screen = SDL_SetVideoMode(SCREEN_WIDTH, SCREEN_HEIGHT, 0, SDL_DOUBLEBUF |SDL_HWSURFACE |SDL_SWSURFACE);
SDL_EnableKeyRepeat(0, 1600000);
if(screen == NULL){
printf("SDL_Init failed: %s\n", SDL_GetError());
}
}
int _tmain(int argc, _TCHAR* argv[])
{
init();
//SDL_Surface* sprite = SDL_BlitSurface(sprite,rcSprite, screen, &rcSprite);
Player player;
//Update Screen
SDL_Flip( screen );
SDL_FreeSurface(screen);
return 0;
}
player.h
#ifndef PLAYER_H
#define PLAYER_H
#include "SDL.h"
#include "SDL_image.h"
#include "SDL_TTF.h"
class Player
{
public:
Player (){
HP = 20;
playerScore = 0;
playerSpeed = 10;
playerJump = 20;
}
~Player();
int getScore() { return playerScore;}
void setSpeed(int speed) { int playerSpeed = speed;}
void setJump (int jump) {playerJump = jump;}
void movePlayer(int x ,int y);
void runRightAnim (SDL_Rect* clip);
void runLeftAnim (SDL_Rect* clip);
void drawPlayer(int x, int y, SDL_Surface* source, SDL_Surface* destination);
static SDL_Rect sprite;
private:
static int HP;
static int playerScore;
static int playerSpeed;
static int playerJump;
static int animRate;
};
#endif
そして最後の1人のplayer.cpp
#include "stdafx.h"
#include "SDL.h"
#include "SDL_image.h"
#include "SDL_TTF.h"
#include "player.h"
void Player::runRightAnim(SDL_Rect* clip)
{
}
void Player::runLeftAnim(SDL_Rect* clip)
{
}
void Player::drawPlayer(int x, int y, SDL_Surface* source, SDL_Surface* destination)
{
SDL_Rect dst;
dst.x = x;
dst.y = y;
SDL_BlitSurface(source,NULL,destination,&dst);
//SDL_BlitSurface(selectionCanvas, NULL, canvas, selectionRect);
}
エラーは

コードは明らかに完成していませんが、このエラーを取り除きたいだけです
