【问题描述】:
在 SFML 中,我想要一个 sprite,但还有其他函数和变量,所以我决定创建一个继承 sprite 类的类,如下所示:
1.播放器.hpp
#pragma once
#include <stdio.h>
#include <SFML/Audio.hpp>
#include <SFML/Graphics.hpp>
class Player : sf::Sprite{
public:
void setup();
void input();
private:
int direction;
void moveRight();
void moveLeft();
sf::Texture textures[8];
};
2(在制品)。播放器.cpp
void Player::setup(){
direction = 0;
textures[0].loadFromFile("images/player_right_still.png");
textures[1].loadFromFile("images/player_right_jump.png");
textures[2].loadFromFile("images/player_right_walk1.png");
textures[3].loadFromFile("images/player_right_walk2.png");
textures[4].loadFromFile("images/player_left_still.png");
textures[5].loadFromFile("images/player_left_jump.png");
textures[6].loadFromFile("images/player_left_walk1.png");
setTexture(textures[0]);
}
void Player::input(){
if (sf::Keyboard::isKeyPressed(sf::Keyboard::Right) || sf::Keyboard::isKeyPressed(sf::Keyboard::D)){
moveRight();
}
if (sf::Keyboard::isKeyPressed(sf::Keyboard::Left) || sf::Keyboard::isKeyPressed(sf::Keyboard::A)){
moveLeft();
}
}
void Player::moveRight(){
}
void Player::moveLeft(){
}
但是当我编译它时,我得到了这个错误:
game.cpp: In function ‘int main()’:
game.cpp:23:27: error: ‘sf::Drawable’ is an inaccessible base of ‘Player’
window.draw(player);
