Brickbreaker ball/paddle bounce issues

Jamie Wyatt

Evening all,

Having a few issues finishing my brickbreaker university project. As it stands the game will start and run, all of the bricks are happy to be hit by the ball, killed by the ball and have the ball bounce off. However, I've tried to use the same code (if (ballRectangle.Intersects(batRectangle)) to get the ball to bounce off the paddle but it's not having any of it.

I've attached the source code, there is also currently a save method in there that I can't get to work (see my other thread - http://www.c-sharpcorner.com/Forums/Thread/120430/saving-an-int-to-a-txt-file.aspx) but it's commented out so it shouldn't cause any compilation issues.

Any help you could offer would be great.

Cheers,
J.

EDIT : Slight update on this, it seems if the ball hits the area that the paddle starts off (dead centre) the ball will bounce as if the paddle is there, regardless of it's actual position.

Does this mean I'm moving the texture but not the rectangle? Is that possible?

Yes mate, sorted that out now so it'll load what ever I've got in that .txt file. Just having issues trying to get it to draw all the bricks again after they've all been destroyed. Any ideas?

I don't know if you fixed the high score loading, but when the initial screeen starts the high score was always zero
To load it before that screen loads I modified this in Breakout.cs

protected override void LoadContent()
{

spriteBatch = new SpriteBatch(GraphicsDevice);

playScreen = new PlayScreen(this.Content, new EventHandler(PlayScreenAction), graphics);
homeScreen = new HomeScreen(this.Content, new EventHandler(HomeScreenAction), graphics);
playScreen.Load("highScore.txt");
screen = homeScreen;

}

Got the saving and loading sorted now with a couple of methods calling StreamWriter & StreamReader.

Just wondered if you had any advice on redrawing all of the bricks after they've all been destroyed?

Again, thanks so much for your help.

for saving the score you will need to save
1:score
2: level
3:lives
4: and maybe player name

Cheers! Sorted the bat issues and the high score is now saved. Just wondering if anyone had any advice on how to make the game "level up" as it were.

As it stands once all of the bricks are destroyed the game will just bounce the ball around the screen, ideally I'd like it to redraw the bricks once all of them have been destroyed but I can't figure out how to get it to do that.

Latest source code is attached.

Cheers,
J.

Had to slow ball down - for me any way
Also next time look at bounding boxes

Also in Breakout class in update put
quitGame();

and the method

public void quitGame()
{
KeyboardState keyState = Keyboard.GetState();
if (keyState.IsKeyDown(Keys.Escape))
{
this.Exit();
}
}
so you can quit with escape key

Try this

if (keyState.IsKeyDown(Keys.Left) && 0 < bat.getPosition().X)
{
bat.moveLeft();
batRectangle.X = (int)bat.getPosition().X;
}

//Move right control
if (keyState.IsKeyDown(Keys.Right) && backgroundRectangle.Width > bat.getPosition().X + (bat.getWidth()))
{
bat.moveRight();
batRectangle.X = (int)bat.getPosition().X;
}
