小编GAD*_*ADO的帖子

我正在使用SFML进行c ++游戏.我已经写了一个用于移动玩家的代码,但是当游戏启动玩家时,移动但是当我离开按钮时玩家返回其原始位置.可以帮助我吗？

主要的:

#include <iostream>
#include <SFML/Graphics.hpp>

int main() {

    sf::RenderWindow window(sf::VideoMode(1320, 840), "Window");
    window.setPosition(sf::Vector2i(150, 50));
    window.setSize(sf::Vector2u(1320, 840));
    window.getPosition();
    window.setVerticalSyncEnabled(true);
    window.setFramerateLimit(5);
    window.getSize();

    while (window.isOpen()) {

        window.clear(sf::Color::White);

        //texture
        sf::Texture texture;
        if (!texture.loadFromFile("/users/gaetanodonnarumma/desktop/background1.png", sf::IntRect(0, 0, 1320, 840))) {
            return -1;
        }

        sf::Texture playerTexture;
        if (!playerTexture.loadFromFile("/users/gaetanodonnarumma/desktop/quadrato-giallo.jpg", sf::IntRect(0, 0, 70, 70))) {
            return -1;
        }

        //sprite
        sf::Sprite backgroud;
        backgroud.setTexture(texture);

        sf::Sprite player;
        double pX = 0;
        double pY = 770;
        player.setTexture(playerTexture);
        player.setPosition(sf::Vector2f(pX, pY));
        player.getPosition();

        sf::Event event;

        while (window.pollEvent(event)) {

            if (event.type == sf::Event::Closed) {
                window.close(); …

我正在使用C ++中的SDL2和OpenGL开发一个简单的应用程序。

问题是我的程序没有绘制三角形。

Rect.hpp（绘制三角形的类）：

#ifndef Rect_hpp
#define Rect_hpp

#include <stdio.h>
#include <iostream>
#define GLEW_STATIC
#include <GL/glew.h>
#include <SDL2/SDL.h>
#include "Shaders.hpp"

using namespace std;

extern GLfloat vertices[];

class Rect
{

public:
 Rect();
 ~Rect();
 void init();
void draw();

private:
 void bind();

 GLuint VAO;
 GLuint VBO;
 GLuint vertexShader;
 GLuint fragmentShader;
 GLuint shaderProgram;
 Shaders shaders;

};

#endif /* Rect_hpp */

Rect.cpp：

#include "Rect.hpp"

GLfloat vertices[] = {
-0.5f, -0.5f, 0.0f,
0.5f, -0.5f, 0.0f,
0.0f, 0.5f, 0.0f,
};

Rect::Rect()
{
VBO = NULL;
vertexShader = …
