我目前正在为一项作业制定一个tic tac toe程序。我遇到的问题是，当我计算我的玩家时（无论是＆＃39; X＆＃39;玩家还是＆＃39; Y＆＃39;玩家），它似乎都在计算两个玩家的数量。例如，在第三场比赛之后，它看到了三场比赛，并将其视为胜利者，尽管只完成了一场比赛的两场比赛和另一场比赛的一场比赛。

TicTacToeViewController(view,model);
view.setVisible(true);
}
}
public class TicTacToeModel
{
double xpos,ypos,xr,yr;
char[][] position = {{' ',' ',' '},
{' ',' ',' '},
{' ',' ',' '}};
public void computePos(int row, int col, int h, int w)
{
xpos=(col+0.5)*w/3.0;
ypos=(row+0.5)*h/3.0;
xr=w/8.0;
yr=h/8.0;
}
public boolean isEmpty(int xpos, int ypos)
{
if(position[xpos][ypos]==' ')
return true;
return false;
}
public void placeO(int xpos, int ypos)
{
position[xpos][ypos]='O';
}
public int putX(){
for(int i=0; i<3;i++){
for(int j = 0;j<3;j++) {
if(position[i][j]==' ') {
position[i][j]='X';
return 0;
}
}
}
return -1; //some error occurred. This is odd. No cells were free.
}
public void printBoard(){
for(int i=0;i<3;i++)
System.out.println(position[i][0]+"|"+position[i][1]+"|"+position[i][2]);

我的问题是，是否有人可以查看我的逻辑，看看为什么游戏只允许三个动作。换句话说，O去，X去，然后O去，游戏宣布胜利者。此外，我不是在寻找代码答案，而是我应该检查哪一部分来修复我的代码。
答案 0 :(得分：4)
我想当你给didWin打电话时我只用了一个＆＃39; ＆＃39;不要以为它真的改变了什么
