我正在使用
LWJGL3
创建一个3D游戏,我希望在后台加载并隐藏窗口,等待我的游戏设置,然后才显示。 我的问题是,即使在
GLFW.glfwHideWindow(窗口)
之后立即调用
GLFW.glfwCreateWindow(宽度、高度、标题、isFullscreen?GLFW.glfwGetPrimaryMonitor():0,0)
窗口闪烁,比加载游戏,比显示(当我想)。
如何防止窗口闪烁?也许我只是更改了
GLFW.glfwCreateWindow
中的一个参数

注意: 在将模型加载到
VAO
之前,我必须创建窗口,因此我无法将
窗口。create()
方法移动到低于它所在位置的位置。
谢谢你的回答

创建一个隐藏窗口。看见在创建窗口之前,设置
GLFW_VISIBLE
属性

GLFW.glfwWindowHint(GLFW.GLFW_可见,GLFW.GLFW_假);
window=GLFW.glfwCreateWindow(宽度、高度、标题、,
isFullscreen?GLFW.glfwGetPrimaryMonitor():0,0);
