나는 게임을 만들고 있으며, 현재 3 개의 클래스, greenpaddle, ball, Game1을 가지고 있습니다. spriteBatch가 Null입니다.
난 내 게임을 실행
는, 디버거 내spriteBatch.Begin();
까지 홉
NullReferenceException이 처리되지 않은는 말한다. 이 나에게 일어난 적이없는,
public class Game1 : Microsoft.Xna.Framework.Game
{
GraphicsDeviceManager graphics;
SpriteBatch spriteBatch;
Ball ball;
GreenPaddle gPaddle;
Texture2D BackGround;
public Game1()
{
graphics = new GraphicsDeviceManager(this);
Content.RootDirectory = "Content";
graphics.PreferredBackBufferHeight = 500;
}
protected override void Initialize()
{
gPaddle = new GreenPaddle();
ball = new Ball(gPaddle);
}
/// <summary>

protected override void LoadContent()
{
// Create a new SpriteBatch, which can be used to draw textures.
spriteBatch = new SpriteBatch(GraphicsDevice);
BackGround = Content.Load<Texture2D>("pongBG");
gPaddle.LoadContent(Content);
ball.LoadContent(Content);
}

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);//Error Line
ball.Update(gameTime);
base.Update(gameTime);
}

protected override void Draw(GameTime gameTime)
{
GraphicsDevice.Clear(Color.CornflowerBlue);
spriteBatch.Begin();//Error Line
spriteBatch.Draw(BackGround, new Vector2(0f, 0f), Color.White);
gPaddle.Draw(spriteBatch);
ball.Draw(spriteBatch);
spriteBatch.End();
base.Draw(gameTime);
}
}
잘못 알고하지 마십시오 이 내 내용은 Game1.cs입니다. 다른 클래스 중 하나가 변경되지 않는 한 그것은
null
안
알았어, 고마워, D –
