어떤 플레이어가 움직이는지를 확인하는 while/while 루프를 만들려고합니다. 지금은 for 루프에서 어떤 플레이가 움직이는 지 확인합니다. 내 코드를 좀 더 명확하고 간결하게 만들려고 노력하고있다.네 명의 게임을 연결하는 플레이어의 움직임을 확인하려면 어떻게합니까?
public static void main(String[] args) {
try (Scanner input = new Scanner(System.in)) {
int height = 6, width = 8, moves = height * width;
ConnectFour board = new ConnectFour(width, height);
System.out.println("Use 0-" + (width - 1) + " to choose a column.");
System.out.println(board);
for (int player = 0; moves-- > 0; player = 1 - player) { // Here is where i check to see who plays
char symbol = players[player];
board.chooseAndDrop(symbol, input);
System.out.println(board);
if (board.isWinningPlay()) {
System.out.println("Player " + symbol + " wins!");
return;
}
}
System.out.println("Game over, no winner.");
}
}
내가의 라인을 따라 더 생각 : : 아래
int playerNb = 0;
while (thegamestarted)
{
if (playerNb == 0)
// Get user input
else
// Get second player input
// Process the input
// Change playerNb to 1 or 0
}
