A pile | 16 //| has a position on the screen and an offset for each | 17 //| card placed on it e.g. a pack has no offset, but the | 18 //| discard pile may be fanned out across the screen. | 19 //| | 20 //| The pile knows how to draw itself, though this may be | 21 //| overridden if the default layout needs to be changed. | 22 //| One or more cards can be removed from the top of a pile, | 23 //| and single cards can be added to the top of a pile. | 24 //| Functions are provided which redraw the screen when | 25 //| cards are added or removed. | 26 //| | 27 //| Cards know which way up they are and how to draw | 28 //| themselves. Piles are lists of cards. Piles know which | 29 //| cards they contain and where they are to be drawn. | 30 //+-------------------------------------------------------------+ 31 #ifndef _PILE_H_ 32 #define _PILE_H_ 33 #include "card.h" 34 35 const int NumCards = 2 * PackSize; 36 37 38 //----------------------------------------------------------------// 39 // A class defining a pile of cards with a position on the screen // 40 //----------------------------------------------------------------// 41 class Pile { 42 public: 43 Pile(int x, int y, int dx = 0, int dy = 0); ~Pile()44 virtual ~Pile(){}; 45 46 // General functions ResetPile()47 virtual void ResetPile() { m_topCard = -1; } 48 virtual void Redraw(wxDC& pDC); 49 50 // Card query functions 51 virtual Card* GetCard(int x, int y); // Get pointer to card at x, y 52 Card* GetTopCard(); // Get pointer to top card 53 virtual void GetCardPos(Card* card, int& x, int& y); 54 // Get position of a card 55 virtual void GetTopCardPos(int& x, int& y); 56 // Get position of the top card GetNumCards()57 int GetNumCards() { return m_topCard + 1; } // Number of cards in pile 58 bool Overlap(int x, int y); // does card at x,y overlap the pile? 59 int CalcDistance(int x, int y); // calculates the square of the distance 60 // of a card at (x,y) from the top of the pile 61 62 // Functions removing one or more cards from the top of a pile 63 virtual bool CanCardLeave(Card* card); 64 Card* RemoveTopCard(); 65 virtual Card* RemoveTopCard(wxDC& pDC, int xOffset = 0, int yOffset = 0); 66 67 // Functions to add a card to the top of a pile AcceptCard(Card *)68 virtual bool AcceptCard(Card*) { return false; } 69 virtual void AddCard(Card* card); // Add card to top of pile 70 virtual void AddCard(wxDC& pDC, Card* card); // Add card + redraw it SetPos(int x,int y)71 void SetPos(int x,int y) {m_x = x;m_y = y;}; 72 73 protected: 74 int m_x, m_y; // Position of the pile on the screen 75 int m_dx, m_dy; // Offset when drawing the pile 76 Card* m_cards[NumCards]; // Array of cards in this pile 77 int m_topCard; // Array index of the top card 78 }; 79 80 #endif // _PILE_H_ 81
