A pile | 17//| has a position on the screen and an offset for each | 18//| card placed on it e.g. a pack has no offset, but the | 19//| discard pile may be fanned out across the screen. | 20//| | 21//| The pile knows how to draw itself, though this may be | 22//| overridden if the default layout needs to be changed. | 23//| One or more cards can be removed from the top of a pile, | 24//| and single cards can be added to the top of a pile. | 25//| Functions are provided which redraw the screen when | 26//| cards are added or removed. | 27//| | 28//| Cards know which way up they are and how to draw | 29//| themselves. Piles are lists of cards. Piles know which | 30//| cards they contain and where they are to be drawn. | 31//+-------------------------------------------------------------+ 32#ifndef _PILE_H_ 33#define _PILE_H_ 34#include "card.h" 35 36const int NumCards = 2 * PackSize; 37 38 39//----------------------------------------------------------------// 40// A class defining a pile of cards with a position on the screen // 41//----------------------------------------------------------------// 42class Pile { 43public: 44 Pile(int x, int y, int dx = 0, int dy = 0); 45 virtual ~Pile(){}; 46 47 // General functions 48 virtual void ResetPile() { m_topCard = -1; } 49 virtual void Redraw(wxDC& pDC); 50 51 // Card query functions 52 virtual Card* GetCard(int x, int y); // Get pointer to card at x, y 53 Card* GetTopCard(); // Get pointer to top card 54 virtual void GetCardPos(Card* card, int& x, int& y); 55 // Get position of a card 56 virtual void GetTopCardPos(int& x, int& y); 57 // Get position of the top card 58 int GetNumCards() { return m_topCard + 1; } // Number of cards in pile 59 bool Overlap(int x, int y); // does card at x,y overlap the pile? 60 int CalcDistance(int x, int y); // calculates the square of the distance 61 // of a card at (x,y) from the top of the pile 62 63 // Functions removing one or more cards from the top of a pile 64 virtual bool CanCardLeave(Card* card); 65 Card* RemoveTopCard(); 66 virtual Card* RemoveTopCard(wxDC& pDC, int xOffset = 0, int yOffset = 0); 67 68 // Functions to add a card to the top of a pile 69 virtual bool AcceptCard(Card*) { return false; } 70 virtual void AddCard(Card* card); // Add card to top of pile 71 virtual void AddCard(wxDC& pDC, Card* card); // Add card + redraw it 72 void SetPos(int x,int y) {m_x = x;m_y = y;}; 73 74protected: 75 int m_x, m_y; // Position of the pile on the screen 76 int m_dx, m_dy; // Offset when drawing the pile 77 Card* m_cards[NumCards]; // Array of cards in this pile 78 int m_topCard; // Array index of the top card 79}; 80 81#endif // _PILE_H_ 82
