GraphicsDevice is null in my XNA Windows Game project
- by indyK1ng
Hello All,
I have just started trying to make a simple game with XNA 3.1 to help myself learn C# and XNA. I have run into a bit of an interesting problem, however. In all of the tutorials, one is supposed to pass GraphicsDevice when instantiating a new spriteBatch object like this:
spriteBatch = new SpriteBatch(GraphicsDevice);
One might even do this:
GraphicsDevice objGraphics = new graphics.GraphicsDevice;
spriteBatch = new SpriteBatch(objGraphics);
where graphics is the GraphicsDeviceManager. However, no matter which version I try, I always get an ArgumentNullException when I try to pass the GraphicsDevice object to spriteBatch's constructor. Almost every tutorial I have found gives the first one and only one mentioned the second option. Has anyone else run into a similar error or know what could be causing this? I am working in Windows 7 x64 with Visual Studio 2008.
