Hey Tangela,

I’ve never heard about the K-Melon browser before, just looked it up. What kind of problems are you having? K-Melon is Gecko based, like FireFox (which works fine) so I’m a bit puzzled what you’re seeing.

Hey Aaron, I didn’t clamp the yaw value because it doesn’t really matter how big it grows I could subtract TwoPi from it every time it becomes larger than TwoPI, but as long as the yaw stays smaller than the largest value a float can store, there should be no problem.

Of course you could change the implementation and use modulus to keep yaw between -TwoPi and +TwoPi, that should work . As you might’ve already guessed, I’m passing radians, not degrees. But you can easily convert between the two using the MathHelper class.

Thanks for your comment!

Hi Roy, I like this camera much more than the one currently at the xna wiki. Good job! I have one question though. You changed the implementation of the Yaw to just be a normal get/set, without using a modulus to keep the value under 360. Can you give an example of an input to the Yaw? Are you passing in specific radians?
