Code Logic Help - Pong

Jordan Hunt · 2012-10-12T05:39:06

Fellow Gamedev'ers, I am trying to finish my Pong Clone by Monday to start my personal journey in to the game programming. I have been slacking off but I realized I am only cheating myself if continue. My resolve to finish this project is strong and nothing is going to get in my way. I have come to a design problem though. I have a Paddle Class for the player but I don't know how to make a automated paddle for the computer. Seeing as they will have very similar attributes but I thought of making the computer paddle a subclass of the player paddle (or inherit from the PlayerPaddle Class). I don't fully understand how to do that though. If I could get some help that would be very much appreciated. using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Graphics; namespace JONG_PongClone_ { class Ball { //The postition of the ball Vector2 position; //Motion of the ball Vector2 motion; //speed of the ball float ballSpeed = 2; //Texture For the ball Texture2D texture; //Collision rectangle for the ball Rectangle screenBounds; //Ball Constructor public Ball(Texture2D texture, Rectangle screenBounds) { this.texture = texture; this.screenBounds = screenBounds; } //Update Method for the ball public void Update() { position += ballSpeed * motion; CheckForCollisonWithTop(); } public void CheckForCollisonWithTop() { if (position.Y < 0) { position.Y = 0; motion.Y *= -1; } if (position.Y + texture.Height > screenBounds.Height) { position.Y = screenBounds.Height - texture.Height; motion.Y *= -1; } } public bool BehindPaddle() { if (position.X > screenBounds.Width || position.X < 0) { return true; } return false; } public void CheckForCollisionWithPaddle(Rectangle paddleLocation) { Rectangle ballLocation = new Rectangle( (int)position.X, (int)position.Y, texture.Width, texture.Height); if (paddleLocation.Intersects(ballLocation)) { position.X = paddleLocation.X - texture.Width; motion.X *= -1; } } public void SetInStartPosition() { motion = new Vector2(1, -1); position.X = (screenBounds.Width - texture.Width) / 2; position.Y = (screenBounds.Height - texture.Height) / 2; } public void Draw(SpriteBatch spriteBatch) { spriteBatch.Draw(texture, position, Color.White); } } } I feel like the smart way of doing this would have the computer paddle be a subclass of paddle. I just don't know exactly how to do that. I am still a little shaky on inheritance and such.

BeerNuts,

I deleted the variables but the game crashed, It said all of those variables are now inaccessible due to the protection level. What do I do now?

Private = No Inheritece. If you want inheritence use protected or public in your class.
