cs193p – Smashtag Update Swift 1.2

Please note, this blog entry is from a previous course. You might want to check out the current one.

To run the Smashtag code with Swift 1.2. are quite extensive:

  • countElements() is now called count()
  • as needs to be replaced with as!
  • reduce() requires the combine parameter named explicitly
  • same with custom methods, its now quite strict …
  • let is now more restrictive, some parameters have to be changed to var (it might be I went a little bit over board here)
  • NSString is no String any more and needs to be cast explicitly
  • if a parameter is set within a closure of the init method, set a default value outside

The updated code is available on GitHub.

cs193p – Project #5 Assignment #5 Step #5 – The Configuration

Please note, this blog entry is from a previous course. You might want to check out the current one.

For the configuration – the settings of the game – create a new class which will handle the communication with the user defaults. Most of the variables stored in the settings are optional, as a way when to use default values.

The columns and the rows setting hold the dimensions of the level “one” of the brick wall:

    struct Const {
        static let ColumnsKey = "Settings.Columns"
        static let RowsKey = "Settings.Rows"
    }

    let defaults = NSUserDefaults.standardUserDefaults()

    var columns: Int? {
        get { return defaults.objectForKey(Const.ColumnsKey) as? Int}
        set { defaults.setObject(newValue, forKey: Const.ColumnsKey) }
    }

    var rows: Int? {
        get { return defaults.objectForKey(Const.RowsKey) as? Int}
        set { defaults.setObject(newValue, forKey: Const.RowsKey) }
    }

cs193p – Project #5 Assignment #5 Step #4 – The Alert

Please note, this blog entry is from a previous course. You might want to check out the current one.

That’s a quick one. In the last completion block of the destroy animation check if there are any bricks left:

    private func destroyBrickAtIndex(index: Int) {
        ...
                    ...
                    UIView.animateWithDuration(1.0, animations: {
                        ...
                        }, completion: { (success) -> Void in
                            ...
                            ...
                            if self.bricks.count == 0 {
                                self.levelFinished()
                            }
                    })
            ...
    }

cs193p – Project #5 Assignment #5 Step #3 – The Bricks

Please note, this blog entry is from a previous course. You might want to check out the current one.

A new structure provides two sets of information – the view of the brick and its relative frame information (without information about the current device information). Store this structure for each brick in a dictionary:

    var bricks = [Int:Brick]()
    
    struct Brick {
        var relativeFrame: CGRect
        var view: UIView
    }

cs193p – Project #5 Assignment #5 Step #2 – The Paddle

Please note, this blog entry is from a previous course. You might want to check out the current one.

Create the paddle lazily. Place it outside (just a little bit) of the game view – which perhaps a bad way to know if it has been created recently. … and make it nice and colorful, with rounded corners etc …

    struct Constants {
        static let PaddleSize = CGSize(width: 80.0, height: 20.0)
        static let PaddleCornerRadius: CGFloat = 5.0
        static let PaddleColor = UIColor.greenColor()
    }

    lazy var paddle: UIView = {
        let paddle = UIView(frame: CGRect(origin: CGPoint(x: -1, y: -1), size: Constants.PaddleSize))
        paddle.backgroundColor = Constants.PaddleColor
        paddle.layer.cornerRadius = Constants.PaddleCornerRadius
        paddle.layer.borderColor = UIColor.blackColor().CGColor
        paddle.layer.borderWidth = 2.0
        paddle.layer.shadowOffset = CGSize(width: 2.0, height: 2.0)
        paddle.layer.shadowOpacity = 0.5
        
        self.gameView.addSubview(paddle)
        
        return paddle
    }()

Please note, this blog entry is from a previous course. You might want to check out the current one.

Task #1

Create a straightforward Breakout game using Dynamic Animator. See the image in the Screen Shots section below to get a general idea of the game, but your UI should not look exactly like the Screen Shot. Creativity is encouraged and will be rewarded.

Hint #1

This assignment is intentionally vague about the feature set of your game to make room for you to show us some creativity. …
