    copied!<p>I'm working on a pong game since I'm pretty new to XNA, and I've ran into a problem... i have 3 classes, <code>"Game1.cs"</code>, <code>"Ball.cs"</code>, and <code>"GreenPaddle.cs"</code>.</p> <p>The <code>GreenPaddle.cs</code> contains <code>Rectangle gpRect</code>, <code>Texture2D gPtexture</code>, <code>Vector2 position</code>.</p> <p>I have movement and such, and in the ball class I have an intersect boolean. But when i try to initialize it in <code>game1.cs</code> i get errors. Here are the classes:</p> <p>GreenPaddle.cs:</p> <pre><code>public class GreenPaddle { Texture2D gPtexture; public Vector2 position; public Rectangle gpRect; public Vector2 origin; public int speed = 2; public GreenPaddle() { } public void LoadContent(ContentManager Content) { gPtexture = Content.Load&lt;Texture2D&gt;("greenpaddle"); position = new Vector2(20, 200); gpRect = new Rectangle((int)position.X, (int)position.Y, gPtexture.Width, gPtexture.Height); } public void Update(GameTime gameTime) { KeyboardState keyState = Keyboard.GetState(); //Movement PaddleMovement(); //Border Collision isCollidingWithBorders(); } public void Draw(SpriteBatch spriteBatch) { spriteBatch.Draw(gPtexture, position, gpRect, Color.LawnGreen); } public Boolean isCollidingWithBorders() { if (position.Y &lt; 83 &amp;&amp; gpRect.Y &lt; 83) { position.Y = 83; gpRect.Y = 83; return true; } if (position.Y &gt; 400 &amp;&amp; gpRect.Y &gt; 400) { position.Y = 400; gpRect.Y = 400; return true; } else { return false; } } public void PaddleMovement() { KeyboardState keyState = Keyboard.GetState(); if (keyState.IsKeyDown(Keys.W)) { position.Y -= speed; gpRect.Y -= speed; } if (keyState.IsKeyDown(Keys.S)) { position.Y += speed; gpRect.Y += speed; } } } </code></pre> <p>Ball.cs:</p> <pre><code>public class Ball { GreenPaddle gPaddle; Texture2D ballTexture; Vector2 ballPosition; Rectangle ballRect; int speed = 2; bool movingUp, movingLeft; public Ball(GreenPaddle paddle) { this.gPaddle = paddle; movingLeft = true; movingUp = true; } public void LoadContent(ContentManager Content) { ballTexture = Content.Load&lt;Texture2D&gt;("ball"); ballPosition = new Vector2(380, 225); ballRect = new Rectangle((int)ballPosition.X, (int)ballPosition.Y, ballTexture.Width, ballTexture.Height); } public void Update(GameTime gameTime) { BallMovement(); } public void Draw(SpriteBatch spriteBatch) { spriteBatch.Draw(ballTexture, ballPosition, ballRect, Color.White); } public void BallMovement() { if (movingUp) { ballPosition.Y -= speed; } if (!movingUp) { ballPosition.Y += speed; } if (movingLeft) { ballPosition.X -= speed; } if (!movingLeft) { ballPosition.X += speed; } if (ballRect.Intersects(gPaddle.gpRect)) movingLeft = !movingLeft; movingUp = !movingUp; if (ballPosition.Y &lt; 85) { movingUp = false; } } } </code></pre> <p>Game1.cs:</p> <pre><code> public class Game1 : Microsoft.Xna.Framework.Game { GraphicsDeviceManager graphics; SpriteBatch spriteBatch; GreenPaddle gPaddle = new GreenPaddle(); Texture2D BackGround; public Game1() { graphics = new GraphicsDeviceManager(this); Content.RootDirectory = "Content"; graphics.PreferredBackBufferHeight = 500; } protected override void Initialize() { Ball ball = new Ball(gPaddle); base.Initialize(); } /// &lt;summary&gt; /// LoadContent will be called once per game and is the place to load /// all of your content. /// &lt;/summary&gt; protected override void LoadContent() { // Create a new SpriteBatch, which can be used to draw textures. spriteBatch = new SpriteBatch(GraphicsDevice); BackGround = Content.Load&lt;Texture2D&gt;("pongBG"); gPaddle.LoadContent(Content); //ball.LoadContent(Content); } /// &lt;summary&gt; /// UnloadContent will be called once per game and is the place to unload /// all content. /// &lt;/summary&gt; protected override void UnloadContent() { // TODO: Unload any non ContentManager content here } /// &lt;summary&gt; /// Allows the game to run logic such as updating the world, /// checking for collisions, gathering input, and playing audio. /// &lt;/summary&gt; /// &lt;param name="gameTime"&gt;Provides a snapshot of timing values.&lt;/param&gt; protected override void Update(GameTime gameTime) { // Allows the game to exit if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed) this.Exit(); gPaddle.Update(gameTime); ball.Update(gameTime);//Error Line base.Update(gameTime); } /// &lt;summary&gt; /// This is called when the game should draw itself. /// &lt;/summary&gt; /// &lt;param name="gameTime"&gt;Provides a snapshot of timing values.&lt;/param&gt; protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); spriteBatch.Begin(); spriteBatch.Draw(BackGround, new Vector2(0f, 0f), Color.White); gPaddle.Draw(spriteBatch); ball.Draw(spriteBatch);//Error Line spriteBatch.End(); base.Draw(gameTime); } } </code></pre> <p>Thats it, I don't know what to do with the initialize part :/</p>
