窗口未关闭GLFW [英] Window not closing GLFW

问题描述

我正在用OpenGL和GLFW编写游戏引擎.但是，以某种方式无法关闭我的窗口.我尝试了很多事情，但是没有效果.我的代码有什么问题?

I am writing a game engine in OpenGL and GLFW. However, somehow my window can't be closed. I tried many things but it doesn't have effect. What's wrong with my code?

我在其中找不到错误的内容-一切对我来说似乎很好.

I can't find the wrong thing in it - everything seems fine to me.

代码:

int running;
GLFWwindow* window;

Window::~Window()
{
    glfwTerminate();
}


Window::Window(int width, int height, const std::string& title)
: m_width(width),
m_height(height),
m_title(title){

    glfwInit();

    if (!glfwInit())

    glfwWindowHint(GLFW_RESIZABLE, GL_FALSE);
    window = glfwCreateWindow(height, width, __FILE__, NULL, NULL);
    if (!window) {
        glfwTerminate();

    }

    running = true;

}

void Window::MainLoop()
{

    do
    {
        glfwMakeContextCurrent(window);

        glClearColor(0.2f, 0.3f, 0.3f, 1.0f);
        glClear(GL_COLOR_BUFFER_BIT);
        glFlush();
        glfwPollEvents();

        Draw();

        glfwSwapBuffers(window);

    }

    while(running);
}

void Window::Draw()
{

    glBegin(GL_TRIANGLES);

    glVertex3f( 0.0f, 1.0f, 0.0f);
    glVertex3f( 1.0f,-1.0f, 0.0f);
    glVertex3f(-1.0f,-1.0f, 0.0f);
    glEnd();
}

谢谢！

推荐答案

有几件事，但问题似乎是您从未设置running = false.

There are several things but the issue seems to be that you never set running = false.

尝试使您的while状况看起来像这样while(!glfwWindowShouldClose(window));

Try making your while condition looking like this while(!glfwWindowShouldClose(window));

此外，如果您希望能够通过按Escape键来关闭窗口，则应该可以:while(!glfwWindowShouldClose(window) && glfwGetKey(window_, GLFW_KEY_ESCAPE) != GLFW_PRESS);

Also if you would like to be able to close the window by pressing escape this should work: while(!glfwWindowShouldClose(window) && glfwGetKey(window_, GLFW_KEY_ESCAPE) != GLFW_PRESS);

还可以考虑将您的int running设置为bool.

Also consider making your int running a bool.

如果您不想更改它们，例如glfwMakeContextCurrent(window);和glClearColor(0.2f, 0.3f, 0.3f, 1.0f);之类的内容就不必放在循环中.

And things such as glfwMakeContextCurrent(window); and glClearColor(0.2f, 0.3f, 0.3f, 1.0f); do not need to be inside your loop if you do not intend to change them.
