hello

i have a question, i am making a simple game with javafx, and i want to use collision detection.
i have got to nodes (circle1 and circle2) which move trough the scene. When they hit eachother
i want them to disappear, but i have no idea how to manage this. I have been looking around on
the internet, but it was way too difficult for me to understand or it was something too different
from my project,
i was hoping someone could help me out

Thanks in advance

Dirk
