    I consistently get a browser crash (on Mac) with WWW.LoadUnityWeb. I already mentioned this in another thread and submitted a bug report over the weekend, but I haven't heard confirmation or anyone else mention this problem.

    So if anyone wants to try crashing their browser, you can try loading:

    and clicking on any of the icons to load a game via WWW.LoadUnityWeb.

    Here's the portion of a firefox crash stacktrace that seems relevant:

    Code (csharp):

    It doesn't crash at all here (newest MacBook Pro 15", Safari 3.0.3), but there is some error in your data-file which prevents Unity from loading it.

    It's great that you submitted a bug. The bug queue is still working, but a server problem is preventing them from actually being put into our bugtracker. We're working on that, so we'll be seeing you bug soon.

    David, what data error do you see? Is it in loading the menu scene, or after selecting one of the games? Maybe it's the same problem, although I can load and run every game individually, bypassing the menu, so I think it's gotta be something to do with WWW.LoadUnityWeb.

    I forgot to include the firefox and safari stacktraces in the original bug report (was waiting for the auto-response, so I could reply with that info, especially if you guys couldn't reproduce it)

    FYI, is just the Unity 2.0 version of, i.e. the web page uses the new clsid to specify the Unity web plugin, and all the web players are rebuilt with Unity 2.0 and saved with the new .unity3d suffix instead of .unityweb.

    The original still runs fine, as it it's still using Unity 1.x, both plugin and players. Another test I ran was just changing that web page to use the 2.0 plugin but still loading the 1.x players. That also loads the menu player fine and then crashes when loading one of the games (but it's good to see that the Unity 2.0 web plugin otherwise seems to run 1.x-built players fine!)

    Next step: I'll see if it crashes on Windows.

    It crashed my browser. I clicked on "Bowl" then my browser crashed. Using Safari 2.04 on a mac mini

    You can't load 1.x unityweb files using a 2.x player. If you go with 2.x do not stream in 1.x unityweb files. So either you go with a 1.x player all the way or you go with a 2.x player all the way, but you can't mix and match. You also can't mix and match the new html with the older 1.x default html.

    OK, good to know (would be great to have an upgrade guide for existing deployed web pages - took some trial and error for me to discover the .unity3d was the new automatically-added suffix and that the plugin had a new clsid)

    In any case, fugudemo.html is the default HTML for Unity 2.0 and is passing .unity3d files to WWW.LoadUnityWeb. I just verified that loading it and clicking Bowl also crashes on my XP system (Bootcamp) on both IE and Firefox. I also uploaded and ran to verify that I can run the Bowl game by itself (I can tell it's the Unity 2.0 version since the smooth-follow script isn't quite right)

    I realized that I I didn't upload all of the Unity 2.0 versions of my minigames, which exhibits another bug that I reported this weekend - WWW.error apparently doesn't get set for missing files, so if you click on Type in the fugugames menu, for example, the load screen just shows 0% and gets stuck.

    The bug report I submitted for both of these issues just uses the sample code in the WWW.LoadUnityWeb script reference to reproduce them.
