Java Tic Tac Toe如何告诉用户没有赢家?
我在这个项目中工作了3天,如果你能帮助我,我不知道我哪里做错了。我真的很感谢你的帮助。我正在尝试创建一个井字游戏。当我运行游戏时,如果玩家X或O赢了,会弹出一条消息说X或O赢了。但是如果非用户a赢了,会弹出一条消息说没有赢家。“赢家”的弹出窗口工作得很好,但“无人赢家”的弹出窗口不工作。如果你能帮我修复它,你真的让我开心Java Tic Tac Toe如何告诉用户没有赢家?,java,android,tic-tac-toe,Java,Android,Tic Tac Toe,我在这个项目中工作了3天,如果你能帮助我,我不知道我哪里做错了。我真的很感谢你的帮助。我正在尝试创建一个井字游戏。当我运行游戏时,如果玩家X或O赢了,会弹出一条消息说X或O赢了。但是如果非用户a赢了,会弹出一条消息说没有赢家。“赢家”的弹出窗口工作得很好,但“无人赢家”的弹出窗口不工作。如果你能帮我修复它,你真的让我开心 public class MainActivity extends AppCompatActivity { MediaPlayer mediaPlayer; int acti

对于(inti=0;i
创建一个用于检查阵列的函数:
int[] gameState ={2,2,2,2,2,2,2,2,2};
如果所有的结果都与2不同,并且没有一个玩家赢了,这意味着是平局
编辑:
使用此功能,它将告诉您的arr是否包含以下项目:
public static boolean my_contains(int[] arr, int item) {
for (int n : arr) {
if (item == n) {
return true;
}
}
return false;
}
然后做:
//Check winning position
for(int[]winningPostion :winningLocation){
//If there is a winning position
if(gameState[winningPostion[0]] == gameState [winningPostion[1]]
&& gameState[winningPostion[1]]== gameState[winningPostion[2]]
&& gameState[winningPostion[0]]!=2){
//Look for the winner
if (activePlayer ==0)
mesg = "O is the winner!";
if(activePlayer==1)
mesg = "X is the winner!";
LinearLayout winnerLayout =(LinearLayout)findViewById (R.id.winnerLayout);
winnerLayout.setVisibility(View .VISIBLE);
TextView winnermesg = (TextView) findViewById(R.id.editText);
winnermesg.setText(mesg);
gameover=true;
}
}
//Here, all winning position have been checked, and gameover is still false
//Check if all X and O have been placed
if(!my_contains(gameSate, 2) && !gameover){
//If so, and gameover is false, then its a tie.
gameover=true;
mesg="there is no winner ";
//README : this may be the wrong layout, its up to you to change it to the good one, but it should pop your message
LinearLayout winnerLayout =(LinearLayout)findViewById (R.id.winnerLayout);
winnerLayout.setVisibility(View .VISIBLE);
TextView winnermesg = (TextView) findViewById(R.id.editText);
winnermesg.setText(mesg);
}
用大括号{}将块括起来
else {
gameover=true;
mesg="there is no winner ";
}
可能是因为这段代码,它无法工作
if (activePlayer ==0)
mesg = "O is the winner!";
if(activePlayer==1)
mesg = "X is the winner!";
else
gameover=true;
mesg="there is no winner ";
试着用大括号,这是最好的练习。像这样:
if (activePlayer ==0){
mesg = "O is the winner!";
}else if(activePlayer==1){
mesg = "X is the winner!";
}else{
gameover=true;
mesg="there is no winner ";
}
目前,您不会跟踪“无赢家”,因为您的
if()
会检查播放的相同符号行
没有赢家意味着没有一行相同的符号,但事实上,董事会是满的。您可以在每次播放符号时不计算格子(数组中的计数2)或增加计数器。只要你打出9格,但没有赢球线,那就是平局
if(gameState[winningPostion[0]] == gameState[winningPostion[1]]
&& gameState[winningPostion[1]] == gameState[winningPostion[2]]
&& gameState[winningPostion[0]] !=2 ) {
//somebody has scored a line, but who?
} else if (haveWePlayed9()) {
//no winner
}
将forloop更改为以下一个。。。。
对于(int i=0;iactivePlayer永远不能与0或1不同,你必须换一种方式来思考。说这是平局!
谢谢你花时间回答我的问题。还有什么其他方式,兄弟。如果你能再给我解释一下的话plz@xenteros几乎是红旗你,因为我笑哈哈-我说几乎,你的答案是完美的问题…苛刻-现在,真正的问题是,您使用**activePlayer**来确定赢家,所以,您应该像代码中的“如果所有框都选中了,但没有线,那么它就是一个平局”——无法告诉您具体的结果,但我希望这个解释能给您一个答案
change the forloop with below one....
