我的程序可以正确跟踪球,但是当我切换到记分板时,它不会输出更新的球数。从控制器场景切换回记分牌场景时,如何更新球数。我也知道代码的许多部分仍然缺失,我只专注于获取更新的变量以首先显示然后从那里显示。

我只希望它显示当我切换回记分板场景时有多少个球
最佳答案
将此行从
ShowBalls.textProperty().bind(new SimpleIntegerProperty(Ball.get()).asString());
对此
ShowBalls.textProperty().bind(Ball.asString());
附带一提,我知道您仍在努力,但由于所有功能都在同一个类中,因此它们都应该是私有的而不是公共的,并且传统上,功能以小写首字母开头,例如
public void ResetScoreboard() {
什么时候应该
private void resetScoreboard() {
变量名
Ball
应该是ball
的情况也一样。我只尝试为类名保留大写的起始字母。如果有机会,我会给Java命名约定提供一个google,它可以帮助每个人在阅读其他代码时停留在同一页上。祝您项目顺利,希望一切顺利
