按键很简单，如果K按下，就会输出“K press“
while (!glfwWindowShouldClose(window)) {
glfwPollEvents();
if (glfwGetKey(window, GLFW_KEY_K) == GLFW_TRUE) {
System.out.println("K press");
}
}
如果鼠标左键按下，就会输出“MouseLeft press“
while (!glfwWindowShouldClose(window)) {
glfwPollEvents();
if (glfwGetMouseButton(window, GLFW_MOUSE_BUTTON_LEFT) == GLFW_TRUE) {
System.out.println("MouseLeft press");
}
}
