   collision detection in 2D game in C#
  Hi, I'm writting a 2D shooting game using C#, i know how to do the rectangle intersection detection, but it is not very accurate since the sprites dont fully fill the rectangles.(2 rectangles intersect each other but the sprites are not actually overlapping). Therefore, could someone pls show me some sample codes of a more accurate collision detection or direct me to such tutorials.Thanks in advance.   
  You probably want pixel-perfect collisions.Try this:http://www.codeproject.com/cs/media/collision3.asp
