Is any reasons - why I know that I can do this by myself (examine the keyboard state every Update and call those events), but it's an ideological/archetectural question: I don't want to "pull" keyboard every time, I need my objects to be "pushed" on a keybo

When the model is in the center of the camera it look okay ( http://www.marmalad.com/milan/sample1.jpg ) but when I place it away from the center (let's say to the right) the model seems to be rotating as well ( http://www.marmalad.com/milan/sample2.jpg ).

How would I go about running a for loop that checks each triangle of the level And from there, what would be the best algorithm to determine if the BoundingSphere is within the triangle Any help is greatly

      • Hi I have been reading through the forum for hours now and there is something I do not quite understand: Any class that is required for readers comes from Microsoft.Xna.Framework.Content.Pipeline. This library is not available for the Xbox 360, thus leading me to the conclusion that it is currently not possible to write a custom ContentTypeReader for the Xbox 360. Is that correct My other problem
