Problem with using the mouse in TurboC++
Hello,
I have been trying lately to make a simple 2 player TicTacToe program in TurboC++ using the graphics library ! I want to implement the program using mouse.
I have written the getmpos() function to get the mouse position on clicking ! However,the mouse gets polled only for the first time,and for the rest of the times the previous input is taken. Hence I am experirncing a problem. Please help me !
(Note:The TicTacToe logic is incomplete.)
Code:
#include <graphics.h>
#include <stdlib.h>
#include <conio.h>
#include<iostream.h>
class TTT
{
int board[3][3];
int origx,origy,player1,player2,move;
public:
void init();
void initboard();
int win();
void drawsym(int,int,int);
void drawcross(int,int);
void drawnought(int,int);
void setmouse();
void getmpos(int*,int*);
void getblock(int*,int*);
void play();
};
void TTT::init()
