This is PlayerUpView.h in view mode; [Download] [Up]
// PlayerUpView is used to track one-ups. (i.e. the number of extra
// "men" left.) It handles displaying them on the screen, too; use
// is fairly obvious:
// 1. Initialize: -initFrame, -setImage:, -setImageFrame:
// -setMargin: (optional method, default is 2.0)
// 2. Reset at start of game play with -setNumUp:
// 3. When an extra "man" is needed, call -decNumUp: If it
// returns YES, then you got one. If it returns NO
// then there are no more left and the game is over.
// 4. If the player is to be awarded a bonus "extra man"
// then call -incNumUp: to add one extra "man".
// If you set up an appropriate BonusTacker (or subclass),
// send it to the PlayerUpView, and then make the
// PlayerUpView one of the delegates to the ScoreKeeper,
// then it will automatically give extra one-ups at the
// right times.
// 5. If you need to know how many are left, then use
// the -numUp method to find out. (If you need to
// inc by more than one, for example, use a combo
// like: [playerUpView setNumUp:([playerUpView numUp] + x)];
// 6. Set the delegate outlet if you want notification of bonus
// men, added/subtracted men, and so on. (Trigger sounds
// and music off the notification, etc.)
// Note that the NeXT archiving works via -read: and -write: so that
// this object can be on a palette.

// -setNumUp: and the next three methods are for use by the game.
- incNumUp:sender; // add a oneUp (awarded bonuses or whatever)
- (int)numUp; // how many oneUps are left
- (BOOL)decNumUp:sender; // use a oneUp & update view
