碰撞检测。我不能让这个工作

Question

我正在尝试制作一个程序，使您产生键入的球的数量。

一半的球在左侧（团队蓝色）生成，另一半在右侧（团队橙色）生成。每个球都必须到达另一侧而不与任何球发生碰撞。为了做到这一点，我首先需要使代码知道何时/是否会与另一个球发生碰撞。

在我的Type: CNAME Name: www value: example.io.s3-website.eu-west-2.amazonaws.com TTL: 1 hour 类中，碰撞检测可以正常工作，但是我不知道如何解决该问题。我没有尝试从GUI类中调用它，但是我也不知道该怎么做。

我一直在寻找此链接以寻求帮助：Checking Collision of Shapes with JavaFX

但这没有帮助。请提出建议。
