我有以下代码
//Querying for move
int playerMove = currentPlayer.PlayCard(myBoard);
//Making move
try {
playMove(playerMove, currentPlayer);
}
catch (IndexOutOfBoundsException e) {
System.out.println("Sorry, I don't think you can do that...");
}
播放器的移动需要与ArrayList中的索引相关联。现在,我的代码隐藏了一个玩家正确做出无效举动的例外,但是我想知道如何修改它,以便不断要求玩家做出举动,直到他们做出有效举动为止。
谢谢! :)
最佳答案
使用while循环
while(!IsMoveValid)
{
int playerMove = currentPlayer.PlayCard(myboard);
IsMoveValid = CheckMoveValidity(playerMove, myBoard);
}
playMove(playerMove, currentPlayer);
和
public bool CheckMoveValidity(int move, Board board)
{
if (move > 0) && (move < board.Length)
{
return true;
} else {
return false;
}
// you could make this helper method shorter by doing
// return (move > 0) && (move < board.Length);
}
注意,这在逻辑上不使用异常:)
