I am have a lot of problems on my XNA 4.0 project. I am trying to have my texture flip horizontally when I the directional value changes. Can any one give me a hint with out directly telling me what to do. I know it's simple but I can't seem to figure it out. I think it has something to do with the update. Any advice?
-This is My SirHero Class

This is my Game1 class.

Yeah, I am pretty sure it has to do something with update or maybe draw. Any advice would be appreciated. Like i said I don't want the answer to my problem, just some pointers or hints in the right direction.
