我一直试图提醒玩家，如果玩家1获胜，那么警告玩家1获胜并确实如此，但它会不断弹出，直到您点击停止显示此对话框。
此外，当我添加检测第二个播放器时，它只是不起作用。
function detectWin () {
if (score + playerTwoScore == 5900 && score > playerTwoScore) {
alert("Player 1 Wins!");
}
}
detectWin();
当我这样做时，它不能显示玩家2获胜。
function detectWin () {
if (score + playerTwoScore == 5900 && score > playerTwoScore) {
alert("Player 1 Wins!");
} else (score + playerTwoScore == 5900 && score < playerTwoScore) {
alert("Player 2 Wins!");
}
}
detectWin();

答案 0 :(得分：1)
每次更新迭代都会调用detectWin函数，因此如果该函数内的条件被解析为true，它将执行其内部的任何内容（本例中的警报函数）。因此，要么在调用一次之后将此条件设为false，方法是添加var＆＃34; finisehd＆＃34;，例如：
function detectWin () {
if (score + playerTwoScore == 5900 && score > playerTwoScore && !finished) {
alert("Player 1 Wins!");
finished = true;
}
}
或者您可以通过更改为可以管理游戏结束的其他状态（http://phaser.io/news/2015/06/using-states-tutorial）来停止更新操作。
