我最近从我的AP Java类中分配了一个项目并遇到了一些困难。该项目的整个目标是创建一个玩家与计算机tic tac toe游戏。我已经成功创建了一个游戏板对象并在数组中输入了某些字符。但是我很困惑，不知道如何处理游戏的以下几个方面：
- 让玩家在玩家之后进行移动 - 让用户输入两个数字，允许他们进行移动而不是硬编码（我一直在使用随机值来测试） - 评估胜利或平局条件。
非常感谢！我最近对此代码感到非常沮丧，任何建议都会有所帮助!!
public class TicTacToeBoard{
private char[][] ttBoard;//initializes the type of array for the board
private boolean gameActive = true;
public TicTacToeBoard(){ //Constructs our board as an object
ttBoard = new char[3][3]; //initialize the 2D array
for(int i = 0; i < ttBoard.length ; i++){
Arrays.fill(ttBoard[i], ' ');
}
}
public void printBoard(){ //we print our board object using this method
for(int i = 0; i<ttBoard.length; i++){
for(int j = 0; j<ttBoard[i].length; j++){
System.out.print(ttBoard[i][j]);
if(j==0 || j==1) //this loop helps separate indices, makes it look like a real board.
System.out.print("|");
}
if(i==0||i==1)
System.out.print("\n-----\n");
}
System.out.println();
}
public boolean makeMove(char player , int i, int j)//here it prompts the player for a move
//and also uses boolean to make the move
{
if(i >= 0 && i<= 2 && j >= 0 && j<= 2)
{
if(ttBoard[i][j] != ' ')
return false;
else
{
ttBoard[i][j] = player;
return true;
}
}
else
return false;
}
public boolean gameOn()//this method will determine whether the game continues
{
return gameActive
}
public void askPlayer(char player) //prompts users turn
{
}
public void askComp() //prompts computers turn
{
}
}
主类代码：
public class TicTacToe{
public static void main(String[] args){
TicTacToeBoard game = new TicTacToeBoard();
game.printBoard();
int count = 1;
while(game.gameOn())
{
if (count%2 == 0)
game.askPlayer('X');
else
game.askComp('O');
count++;
}
game.printBoard();
}
}
答案 0 :(得分：0)
你想要的第一个功能是这样吗？ （不确定我真正得到你想要的东西）
public void askPlayer(char player) {
Scanner sc = new Scanner(System.in);
bool ok=false,ok2=false;
int one, two;
while(!ok2){//run while the input wanted is already taken
while(!ok){//run while the input for the first coordinate isn't correct
System.out.print("Enter first coordiante : ");
try{
one=sc.nextInt();
if(one<1 || one>3)//in the array?
System.out.println("Wrong input");
else
ok=true;
}catch(InputMismatchException e){//a number is entered?
System.out.println("Wrong input");
}
}
ok=false;
while(!ok){//same for second coordiante
System.out.print("Enter second coordiante : ");
try{
two=sc.nextInt();
if(two<1 || two>3)
System.out.println("Wrong input");
else
ok=true;
}catch(InputMismatchException e){
System.out.println("Wrong input");
}
}
if(ttBoard[one-1][two-1]!=' ')//taken?
System.out.println("Case already taken");
else
ok2=true;
}
ttBoard[one-1][two-1]=player;//affect players character
}
