什么时候应该是我的循环的条件
在我的程序中，当我的两个矩形匹配时，分数增加1。但它只能工作一次。我知道我需要在我的程序中加一个循环，我只是遇到一些麻烦应该是什么条件。而不是if语句我放了一个while（）循环，它仍然无法正常工作。请帮忙。你会看到问题的起点，我会发表评论。

答案 0 :(得分：1)
移动变量total，如下所示：
public class TransoFo extends Application {
private int total;
public void start(Stage stage) {
从：
// problem starts here
if (bounds.getMinY() <= bBounds.getMaxY() && bounds.getMaxY() >= bBounds.getMinY()) {
total += 1;
但是，您仍然需要修改总计显示的方式。它覆盖了以前的总数
希望这有帮助。
