In xna when you have a sprite that doesnt rotate it's very easy to get the four corner of a sprite to make a hitbox, but when you do a rotation the points get moved and I assume there is some kind of math that I can use to aquire them.

I am using the four points to draw a rectangle that visually represents the hitboxes.

I have seen some per-pixel collission examples but I can forsee they would be hard to draw a box/'convex hull' around.

I have also seen physics like farseer but I'm not sure if there is a quick tutorial to do what I want.

What do you guys think is the best approach becuase I am looking to complete this work by the end of the week.
