Question

我正在尝试用Java / LWJGL制作一个简单的游戏。我正在关注在Windows上制作的教程，我正在使用mac。我复制了他的代码，为角色打开了一个窗口角色，程序立即崩溃，给了我一个很长很奇怪的错误，可能与指针有关（我实际上并不知道）。以下是创建窗口的行，我在其中使用了属性中定义宽度和高度的窗口：

 window = glfwCreateWindow(width, height, "Flappy Bird", NULL, NULL);

当我在我的Mac上运行它时，它给了我这个错误：

还会弹出一个窗口，上面写着“java在使用libglfw.dylib插件时意外退出。”

我是否安装了LWJGL错误或我的代码是否有缺陷？谢谢你的帮助！

Answer 1

如果您使用的是LWJGL 3，我建议您按照Oskar的视频教程设置项目和显示。

Workspace setting

Display tutorial

尝试在glfwCreateWindow调用中使用MemoryUtil.NULL代替标准null。

Answer 2

确保使用jvm标志-XstartOnFirstThread运行应用程序。尽管这似乎与OSX有关。 See this SO Answer what this argument means
