我目前正在制作一个程序，有4名玩家轮流投掷n枚硬币。第一个获得16分的玩家获胜。玩家每次投掷硬币都能获得分数。他得到的分数等于他掷出正面的次数。如果他没有掷出正面，那么他将失去下一回合。如果他投掷3次正面，那么他将获得一次额外的机会，并再次投掷硬币。如果他掷出少于3次正面，则该轮到下一个玩家。玩家必须获得16分才能获胜。如果一个玩家得到14分，投掷2次正面，那么他就赢了，但如果他投掷n次正面，超过16分，那么他就失去了一半的分数，也失去了轮到他的机会。他必须得16分才能赢。
我的问题在于游戏类。如果玩家连续掷出3个正面，我似乎无法让他再次进入游戏。

编辑
只删除第一行player_index = (player_index + 1) % n_players;in game.nextPlayer()
我将给您一个一般的提示，因为您有相当多的代码，并且将我的解决方案塞进将是危险的。
考虑"运行"的概念-如果一个玩家有一个正面，那么他们的运行是1。如果他们连续两次正面向上，那么他们连续2次正面向上。如果他们已经连续三次，那么他们的运行计数重置，并且他们的状态被设置为EXTRA_TURN。
像这样:
private int runCount = 0;
// should only *ever* be called after a heads
public void onRun(boolean hadHeads) {
if(hadHeads) {
runCount++;
if(runCount == 3) {
runCount = 0;
setState(EXTRA_TURN);
System.out.println("Three heads in a row - you get an extra turn!");
} else {
runCount = 0;
}
}
