私の質問は、一般的なゲーム アルゴリズムに関するものではありません。「続行しますか? true または false を入力してください」という質問に「true」と答えると、プログラムは次のように出力します。
"Player one, throw your shape(rock, paper, scissors)!
Player two, throw your shape(rock, paper, scissors)!"
したがって、最初のサイクルでは値を入力できますが、2 番目のサイクルでは入力できません。どうすれば修正できますか？ありがとう。
コード：
public static void main(String[] args) {
String playerOne;
String playerTwo;
Scanner myScan = new Scanner(System.in);
boolean playAgain = true;
do
{
System.out.println("Player one, throw your shape(rock, paper, scissors)! ");
playerOne = myScan.nextLine();
System.out.println("Player two, throw your shape(rock, paper, scissors)! ");
playerTwo = myScan.nextLine();
if (playerOne.equals("scissors") && playerTwo.equals("rock"))
{
System.out.println("Player one lost! Playr two won!");
}
else if (playerOne.equals("scissors") && playerTwo.equals("paper"))
{
System.out.println("Player one won! Player two lost!");
}
else if (playerOne.equals("rock") && playerTwo.equals("paper"))
{
System.out.println("Player one lost! Player two won!");
}
else if (playerOne.equals("rock") && playerTwo.equals("scissors"))
{
System.out.println("Player one won! Player two lost!");
}
else if (playerOne.equals("paper") && playerTwo.equals("scissors"))
{
System.out.println("Player one lost! Player two won!");
}
else if (playerOne.equals("paper") && playerTwo.equals("rock"))
{
System.out.println("Player one won! Player two lost!");
}
System.out.println("Do you want to continue? Enter true or false.");
playAgain = myScan.nextBoolean();
}while(playAgain);
}
}
