|
//| Description: |
|
|
//| The base class for holding piles of playing cards. |
|
|
//| This is the basic building block for card games. A pile |
|
|
//| has a position on the screen and an offset for each |
|
|
//| card placed on it e.g. a pack has no offset, but the |
|
|
//| discard pile may be fanned out across the screen. |
|
|
//| |
|
|
//| The pile knows how to draw itself, though this may be |
|
|
//| overridden if the default layout needs to be changed. |
|
|
//| One or more cards can be removed from the top of a pile, |
|
|
//| and single cards can be added to the top of a pile. |
|
|
//| Functions are provided which redraw the screen when |
|
|
//| cards are added or removed. |
|
|
//| |
|
|
//| Cards know which way up they are and how to draw |
|
|
//| themselves. Piles are lists of cards. Piles know which |
|
|
//| cards they contain and where they are to be drawn. |
