Small issue with documentation

Hi all, this isn’t a big problem but there is a little wonkiness on

First, the previous page of the defines the Texture2D to be called textureBall, while this page calls it ballTexture.

Second, the last code snippet on the page has calls to Math.Min and Math.Max. Maybe the doc should mention that “using System” needs to be added?

Of course these kinds of things should be obvious to any experienced programmer, but given the doc is meant for beginners it could be a problem for someone writing their first program.

I think this is supposed to be MathHelper?

Regarding the other thing, yeah, that’s a rookie mistake, OR the writer checking to make sure a beginner can solve issues :wink:
