Thread: javafx collision detection (simple)

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

Here's a thought. Read this tutorial that has a good discussion of collision detection and how to program it in JavaFX, and tell us what you don't understand about it. You might find this author's whole tutorial (starts here) and do that to cement what is being presented.

How 'bout ".contains" or ".intersects" methods for your circles?

Try something like this - it adds a flag so that the routine does not "forget" that a collision was detected:

private void checkBounds(Shape block) {
boolean collisionDetected = false;
for (Shape static_bloc : nodes) {
if (static_bloc != block) {
static_bloc.setFill(Color.GREEN);

if (block.getBoundsInParent().intersects(static_bloc. getBoundsInParent())) {
collisionDetected = true;
}
}
}

if (collisionDetected) {
block.setFill(Color.BLUE);
} else {
block.setFill(Color.GREEN);
}
}
