super useful - thanks again for sharing your knowledge, and extra thanks for sharing your source code x

Thanks man, this is exactly what I was looking for, just a very simple basic guide on how to actually do it, without the fancy jargon.

[chrischen]

your videos are saving me in my graphics course, thank you very much!

If your keyCallback function is contained in a class, declare it as static; to make sure that the function is not bound with the class.

i get an error (variable or field keyCallback declared void)

[marcstephens]

All, Thank you. Is there a source that I can learn to how to use this to modify variables with my key input. This does not seem to allow me to pass in extra variables in the gflwSetKeyCallback. So when it calls the keyCallback() method it cant work with extra variables. I am a new programmer so thank you.

Hi! Thanks for the tutorial! I want to do something when the key is released, so I put it
if (glfwGetKey(window, GLFW_KEY_UP))
{
if (glfwGetKey(window, GLFW_KEY_UP) == GLFW_PRESS)
{
cout << "press" << glGetString(GL_VERSION) << endl;

}
else if (glfwGetKey(window, GLFW_KEY_UP) == GLFW_RELEASE)
{
cout << "release" << glGetString(GL_VERSION) << endl;

}
}
But it never print "release" after I released the key. May I know what's the error done here?
