.当我把它移到一个单独的类中时,Quad就消失了[重复]

我终于得到了一个处理纹理的quad,为了清理我的代码,我决定把它移到一个单独的类中,但现在它消失了,没有任何错误消息。

主文件:

#include <glad/glad.h>
#include <GLFW/glfw3.h>
#include <stb/stb_image.h>

GLfloat vertexes[]
{

    0.5,  0.5, 0.0,   1.0, 0.0, 0.0,   1.0, 1.0,

const int width = 1900;
const int height = 1200;

int main()
{
    glfwInit();

    window window(width, height, "Voxel Engine");

    gladLoadGL();
    
    glViewport(0, 0, width, height);

    // shader
    shader_program shader("src/shaders/vertex_shader.shader", "src/shaders/fragment_shader.shader");

    model model1(vertexes);

    /*// vao and vbo
    unsigned int vbo, vao;

    glGenBuffers(1, &vbo);

    glGenVertexArrays(1, &vao);

    glBindVertexArray(vao);

    glVertexAttribPointer(2, 2, GL_FLOAT, GL_FALSE, 8 * sizeof(float), (void*)(6 * sizeof(float)));
    glEnableVertexAttribArray(2);

    glBindVertexArray(0);
    glBindBuffer(GL_ARRAY_BUFFER, 0);*/

    texture test_img("resources/test_img.png", GL_TEXTURE0, GL_RGB, GL_UNSIGNED_BYTE);
    test_img.uniform_shader(shader, "tex_0", 0);

    while (!glfwWindowShouldClose(window.glfw_window))
    {
        glfwPollEvents();

        glClearColor(0.08, 0.12, 0.24, 1.0);
        glClear(GL_COLOR_BUFFER_BIT);

        shader.use();

        //glBindTexture(GL_TEXTURE_2D, texture1);
        test_img.bind();

        glBindVertexArray(model1.vao);

        glDrawArrays(GL_TRIANGLES, 0, 6);

        window.swap_buffers();
    }

    glDeleteVertexArrays(1, &model1.vao);

    glDeleteBuffers(1, &model1.vbo);

    //glDeleteTextures(1, &texture1);

    test_img.destroy();
    shader.destroy();
    window.destroy();

    glfwTerminate();
    return 0;
}

型号标题:

#ifndef MODEL_CLASS_H
#define MODEL_CLASS_H

#include <glad/glad.h>

class model
{
    public:
        unsigned int vao, vbo;

        model(GLfloat vertexes[]);

        void render();

        void destroy();
};

#endif

最后,模型c++文件:

#include <model.h>

model::model(GLfloat vertexes[])
{
    // vao and vbo
    glGenBuffers(1, &vbo);

    glBindBuffer(GL_ARRAY_BUFFER, vbo);
    glBufferData(GL_ARRAY_BUFFER, sizeof(vertexes), vertexes, GL_STATIC_DRAW);

    glGenVertexArrays(1, &vao);

    glBindVertexArray(vao);

    glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 8 * sizeof(float), (void*)0);
    glEnableVertexAttribArray(0);

    glVertexAttribPointer(1, 3, GL_FLOAT, GL_FALSE, 8 * sizeof(float), (void*)(3 * sizeof(float)));
    glEnableVertexAttribArray(1);

    glVertexAttribPointer(2, 2, GL_FLOAT, GL_FALSE, 8 * sizeof(float), (void*)(6 * sizeof(float)));
    glEnableVertexAttribArray(2);

    glBindVertexArray(0);
    glBindBuffer(GL_ARRAY_BUFFER, 0);
}

我发现由于某种原因,vbo和vao没有正确创建,但让我困惑的是,我直接从main.cpp文件中复制了代码,但现在它不起作用。
