How do I set up a "Ghost" collision sensor?

    I'm making a simple basketball sim, and I want to make a sensor just below the net that will +1 to a variable, so I can make a functional scoreboard. I can't make a solid object, because that would mess with the ball, so the ball needs to be able to pass through unhindered, while the "ghost" object detects a "collision", so I can add points. If anyone could help, I'd really appreciate it.

    Use OnTriggerEnter in order to get the event for when this happens.

    However for your example you might need to put a trigger within the ring and then read the velocity of the ball as it exits the trigger so you know it passed through the ring from top to bottom.
