Challenge: NSBezierPath-base Hit Testing

[samatron]

Managed to get this one working.

1. Added a variable for the die path:

var diePath: NSBezierPath?

2. Altered the draw code to update the variable in func drawDieWithSize()

   self.diePath = NSBezierPath(roundedRect: dieFrame, xRadius: cornerRadius, yRadius: cornerRadius)
   self.diePath!.fill()

3. Changed the hit test to use the path

   override func mouseDown(theEvent: NSEvent) {
   Swift.print(“mouseDown”)
   let pointInView = convertPoint(theEvent.locationInWindow, fromView: nil)
   pressed = (self.diePath?.containsPoint(pointInView))!
   }

One must also modify mouseUp to prevent changing the number of dots when clicking outside the dice bounds :

    override func mouseUp(with event: NSEvent) {
    print("mouseUp clic count: \(event.clickCount)")
    
    let pointInView = convert(event.locationInWindow, from: nil)
    if event.clickCount == 2 && (self.diePath?.contains(pointInView))! {
        randomize()
    }
    pressed = false
}
