好吧,所以我非常接近完成这个计划。我理解为什么我的程序没有采取行动,我能够解决它,但现在我正在努力检查获胜者。我意识到我的winGame()
函数应该在某种程度上或者在while循环中结束游戏。但是,当我试图做一些调试来解决一些问题时,我意识到一些令人不安的事情。它总是说它是一个平局,即使它不应该是。这些是很小的事情,我很惭愧,不理解,我真的希望得到一些帮助,我可以解决它。另外,我知道如果有胜利的话,应该有一段时间或者做while循环来结束游戏。我只是不确定在哪里放,所以如果您有任何建议,请告诉我。
*请注意,在我的有效移动函数中有一个小数组,我打算将其作为一个静态const数组。我的get函数返回名称中的值(例如getIval()返回单元格对象的初始值),而我的set函数只是适当地赋值。
bool TicTacToe::validMove(char move){
char options[9] = { '1','2', '3', '4','5','6','7', '8','9' };
bool validate = false;
for ( int i = 0; i < 9; i++ ){
if ( move == options[i]){
validate = true;
}
}
return ( validate );
}
void TicTacToe::setMove( char move ){
for ( int i = 0; i < ROW; i++ ){
for ( int j = 0; j < COL; j++ ){
if ( board[i][j].getiVal() == move ){
board[i][j].setiVal( players[currentPlayer].getMarker() );
switchPlayer();
break;
}
}
}
}
void TicTacToe::makeAMove(){
char move;
int turns = 1;
bool validate = true;
do{
cout << "Player " << (getCurrentPlayer() + 1) << " make a move." << endl;
cin >> move;
if ( validMove( move ) ){
if ( turns > 4 ){
cout << "Nested if-else statement." << endl;
winGame();
setMove( move );
}
else
setMove(move);
}
else{
cout << "Invalid Move. Please reenter." << endl;
cin >> move;
}
DrawBoard();
turns++;
} while ( turns <= 9 );
}
bool TicTacToe::winGame(){
cout << "Calling winGame() " << endl;
bool validate = false;
int k = 0;
for ( int i = 0; i < COL; i++ ){
//check column wins
if ( board[0][i].getMarker() == board[1][i].getMarker() && board[1][i].getMarker() == board[2][i].getMarker() && board[2][i].getMarker() != (' ')){
cout << "Column win " << endl;
validate = true;
break;
}
//check row wins
else if ( board[i][0].getMarker() == board[i][1].getMarker() && board[i][1].getMarker() == board[i][2].getMarker() && board[i][2].getMarker() != (' ')){
cout << "Row win." << endl;
validate = true;
break;
}
}
if( board[0][0].getMarker() == board[1][1].getMarker() && board[1][1].getMarker() == board[2][2].getMarker() && board[2][2].getMarker() != (' ')){
cout << "Diagonal 1" << endl;
validate = true;
}
else if ( board[0][2].getMarker() == board[1][1].getMarker() && board[1][1].getMarker() == board[2][0].getMarker() && board[2][0].getMarker() != (' ') ){
cout << "Diagonal 2 " << endl;
validate = true;
}
else{
cout << "It's a draw!" << endl;
validate = true;
}
return (validate);
}

此代码存在3个问题。
这些很容易修复。
Pass转入WinGameme函数并创建一个额外的if语句 检查是否转弯== 9
void TicTacToe :: makeAMove(){ char move; int turns = 1; bool validate = true;
do{
cout << "Player " << (getCurrentPlayer() + 1) << " make a move." << endl;
cin >> move;
if ( validMove( move ) ){
if ( turns > 4 ){
cout << "Nested if-else statement." << endl;
setMove( move );
if (winGame(turns)==true)
{
break;
}
}
else
setMove(move);
}
else{
cout << "Invalid Move. Please reenter." << endl;
cin >> move;
}
DrawBoard();
turns++;
} while ( turns <= 9 );
cout << "Game Over" <<endl;
}
然后
bool TicTacToe::winGame(int turns)
{
cout << "Calling winGame() " << endl;
bool validate = false;
int k = 0;
for ( int i = 0; i < COL; i++ )
{
//check column wins
if ( board[0][i].getMarker() == board[1][i].getMarker() &&
board[1][i].getMarker() == board[2][i].getMarker() &&
board[2][i].getMarker() != (' ')){
cout << "Column win " << endl;
validate = true;
break;
}
//check row wins
else if ( board[i][0].getMarker() == board[i][1].getMarker() &&
board[i][1].getMarker() == board[i][2].getMarker() &&
board[i][2].getMarker() != (' ')){
cout << "Row win." << endl;
validate = true;
break;
}
}
if( board[0][0].getMarker() == board[1][1].getMarker() &&
board[1][1].getMarker() == board[2][2].getMarker() &&
board[2][2].getMarker() != (' ')){
cout << "Diagonal 1" << endl;
validate = true;
}
else if ( board[0][2].getMarker() == board[1][1].getMarker() &&
board[1][1].getMarker() == board[2][0].getMarker() &&
board[2][0].getMarker() != (' ') ){
cout << "Diagonal 2 " << endl;
validate = true;
}
else
{
if (turns==9)

cout << "It's a draw!" << endl;

答案 1 :(得分:2)
它总是说它是平局,即使它不应该是平局。
原因是您的winGame
函数在检测到行或列获胜者时不会立即返回。相反,如果行或列获胜,则会进行额外检查以无缘无故地检查对角线获胜者。
代码应在检测到列或行获胜者时立即返回,而不是进入对角线检查。如果代码以这种方式完成,也不需要validate
变量。
如果采用更系统化的方法,只需编写3种不同的获胜方式的代码:按行,按行和按对角线,这样会更好。如果其中任何一个是获胜者,那么立即返回。
此外,在检查行,列或对角线之前检查是否首先检查标记会更快。您的代码最后会对标记进行空白检查,因此在不需要调用它时会不必要地调用getMarker
。
该代码说明了所提出的观点:
bool TicTacToe::winGame()
{
char marker;
// row check
for ( int i = 0; i < COL; i++ )
{
marker = board[i][0].getMarker(); // get the initial marker
// test if something is there
if ( marker != ' ')
{
// now test the other two markers to see if they match
if ( board[i][1].getMarker() == marker &&
board[i][2].getMarker() == marker )
return true;
}
}
// column check
for ( int i = 0; i < COL; i++ )
{
marker = board[0][i].getMarker();
if ( marker != ' ')
{
if ( board[1][i].getMarker() == marker &&
board[2][i].getMarker() == marker )
return true;
}
}
// check diagonals next
//... (code not shown)
return false; // if the diagonals fail
}
我没有编写代码来测试对角线,但你应该明白这个想法。行和列检查是在单独的循环中完成的(没什么特别的)。如果在这些循环的任何迭代中都有赢家,则返回值为true
,表示获胜者。
