Unity Technologies released a new preview build of Unity 3 this week, so I revisited the issues I mentioned in my previous post. Most have already been fixed.

Updated Issues

• My paper is now lit normally. Apparently this was a Unity bug after all, or I needed to restart Unity for some reason.
• Some sounds that hadn’t been playing are now working. I hadn’t even mentioned this one last week, assuming that it was just another example of assets becoming disconnected by the project conversion.
• Lightmapped textures now display correctly in the material inspector.
• I worked through the compiler error, that System.IO.FileInfo.Open() no longer accepts 0 or 1 arguments. Some of the documented overloads appeared to be missing:

  public void WontCompile()
  {
      FileInfo theSourceFile = null;
      Stream reader = null;
  	
      theSourceFile = new FileInfo (Application.dataPath + "/puzzles.txt");
      if ( theSourceFile != null ) 
      {
          reader = theSourceFile.Open(FileMode.Open); // COMPILE ERROR: NO OVERLOAD TAKES 1 ARG
  	reader = theSourceFile.Open(FileMode.Open, FileAccess.Read); // NO ERROR
      }
  }
  

  It was easy enough to add the missing arguments. But while I was reproducing the problem for Unity Tech support (who were very helpful by the way), we managed to clear the error by doing two things: changing the API Compatibility project setting from .NET 2.0 Subset to .NET 2.0; and creating a standalone build of the game. And now that the error is gone, I can’t get it to come back, even by setting API Compatibility back to 2.0 Subset. Strange.

New Issues
I noticed two issues that I hadn’t before. One is a bug, the other is a change that I’m going to have to get used to.

• Clicking on a texture of a Material brings up the new,, nice texture selection dialog. Unity used to instead jump the Project view to the texture. I’m finding it inconvenient that I can’t jump from a material directly to the texture’s import settings. Meshes and Materials have little dots next to them; clicking on the dot jumps you to that asset.
  

  The inspector shows a hotspot next to Meshes and Materials that take you to that asset. Textures don't have it.

  
  Hopefully a similar shortcut will be added for textures.
• Maximize on Play doesn’t restore the editor windows once the game has stopped. This is accompanied by an error in the console.
