I'm working on a pong game and am stuck with my collision between my "ball" and my "paddle2" objects. It seems my paddle position wont move with my paddle object, so instead of the ball bouncing off my paddle it bounces off an invisible circle where the paddle started. also instead of rebounding off the paddle start pos it goes to 0, 0 and comes down from the top left corner. my collision code is surounded in ////////////////////////////////// if that helps lol
Any help would be much appreciated!
ps. I know my code will look like crap to everyone but this is my first ever project and i am still learning the basics.
public class Game1 : Game

GraphicsDeviceManager graphics;

Rectangle background = new Rectangle(0, 0, 850, 510);
