I kept getting a InvalidOperationException before, I just rewrote it and it worked fine. I thought the exception was because the xml array attributes did not work with List<T>. Thanks Shawn!

[quote user="Shawn Hargreaves"]Replace ArrayList with List<Behavior> (or List<object> if you really want the exact same loosely typed semantics as ArrayList). Since generics were added in the 2.0 CLR, there is never a good reason to use ArrayList any more. It is only kept around for backward compatibility with older ...

I'm designing a behavior tree system for the AI of our game. There's a Behavior base class and several derived Behaviors. Each behavior has its own children defined as a generic list (List<Behavior>). I want to do something with generic lists that appears to be limited to ArrayLists  from looking at tons of documentation and ...

[quote user="jwatte"]Are you talking about a virtual object and virtual camera, or a real object and a real camera? If you want to do image recognition, then I suggest you look for things that look like bar codes, and if you find something that looks enough like a bar code, that's the front. In general, image recognition of object ...

My teacher and I are trying to find a way to see if the face of a 3D model is facing the camera. For example, we want to model an object with a barcode on some part of it. We would want to detect when the face with the barcode on it is facing the camera. I was wondering if anyone here did something similiar and might have some tips.

Yeah there was a random in each object. That makes sense, I'll try it out.

I'm trying to instantiate multiple objects with  random movement. But they are created so close(miliseconds) to each other that seeding a time value doesn't matter. The 'random' values always end up the same. Does anyone know a way to deal with this?

    So far in my game I have xml level data that includes information like the background and enemies with their time, position, type, etc. Which works fine so far. I'm having trouble coming up with a good editor to make these files though. First I came up with just a text based editor. But putting in positions manually ...

Oh ok. I do eventually want to get a Xbox 360 anyway.(now I wish Nintendo had its own creator's club for wii/ds...heh)

 How will Xbox Live Community effect PC development? Would it be easy to make a game for community with just a PC? I have no Xbox 360(just a controller for my PC). I wonder if there will eventually be a Windows Live Community?Otherwise, I can't wait for XNA Game Studio 3.0, I just got Visual Studio 2008 from Microsoft Dreamspark.
