java - 在 LibGDX 中添加多个窗口？

Question

我想从我的 DekstopLauncher.java 创建多个游戏窗口。第二个应该能够与第一个交互，例如请求一个字符串。

有可能吗？以及如何？

这是我在 DeskopLauncher 类中尝试的:

这是创建第一个窗口:

LwjglApplicationConfiguration configForTiles = new LwjglApplicationConfiguration();
TilePresets tilesWindow = new TilePresets();
LwjglApplication tiles = new LwjglApplication(tilesWindow, configForTiles);

这是第二个

LwjglApplicationConfiguration configForMap = new LwjglApplicationConfiguration();
MapMaker mapWindow = new MapMaker();
LwjglApplication map = new LwjglApplication(mapWindow, configForMap);

只创作一件作品。但如果同时添加两者，它会给我这个错误:

基本上，您可以在单独的进程中运行每个窗口(使用答案 here 了解如何实现下面使用的 JavaProcess):

public class Tiles {
   public static void main(String[] args) {
      LwjglApplicationConfiguration configForTiles = new LwjglApplicationConfiguration();
      TilePresets tilesWindow = new TilePresets();
      LwjglApplication tiles = new LwjglApplication(tilesWindow, configForTiles);
   }
}

Wrapper.java 是主要入口点。这是启动两个窗口的地方:

public class Wrapper {
   public static void main(String[] args) {
      // Launch mapWindow regularly 
      LwjglApplicationConfiguration configForMap = new LwjglApplicationConfiguration();
      MapMaker mapWindow = new MapMaker();
      LwjglApplication map = new LwjglApplication(mapWindow, configForMap);

      try {
         int res = JavaProcess.exec(Tiles.class); // Where the second window is shown
      } catch (IOException e) {
         e.printStackTrace();
      } catch (InterruptedException e) {
         e.printStackTrace();
      }
   }
}

信用警报! 我有一个类似的问题，我在某个地方找到了这个解决方案，但我不记得在哪里。当我找到它时，我会在此处发布源代码。
