如何将 libGDX GWT 游戏转换为 1.9.5 版？
How do I convert a libGDX GWT game to version 1.9.5?
我正在尝试将我的游戏升级到 libGDX 1.9.5。游戏在桌面上运行良好，但当我尝试 build HTML 版本时，我收到以下错误：

从历史上看，使用 GWT 对我来说最大的挑战是 VisUI 和 gdx-kiwi，但我已经访问了他们的维基并在我的 gradle 文件中更新了他们的版本，如下所示：

原来问题的其余部分是 VisUI 中的错误 - 最新更新尝试使用 GWT 不支持的线程 class。

从您的 gradle GWT 构建中删除关闭标志：
