Do While循环似乎不起作用

因此,无论playerWins是否返回true或false,do-while循环都将继续。我正在努力做到这一点,这样如果球员赢了,比赛就结束了。我不知道我这辈子到底出了什么问题。我真的非常感谢所有的帮助/提示。非常感谢。

int credibility = INITIAL_CREDIBILITY_LEVEL;


displayIntro();

userName = IR4.getString("\n" + "What are you called in your city?");

  for(counter = 1; counter <= NBR_OF_ROUNDS; counter ++)
  {
    do
    {
    if(counter == 1)
    {
      displayFirstRoundHeader(userName); 
    }
    else 
    {
      displayRoundHeader();
    }
    combination = IR4.getRandomNumber(STARTING_LOW, STARTING_HIGH);
    System.err.println(combination);
    playerWins = playRound(combination);

    credibility -= CREDIBILITY_LOST;

    if(playerWins)
      System.out.println("Yay you win");
    else if(credibility == 0)
    {
    displayRoundLossText(userName, credibility, combination);
    displayLossText(userName);
    }
    else
      displayRoundLossText(userName, credibility, combination);
    }
    while(!playerWins);
