Modifying variables on first collision only

So let’s say I have a bouncing ball that I want to flip a bool on, but I only want the bool to flip on the first OnEventHit. Is there a lightweight way to ignore the subsequent hits generated by the ball bouncing? I feel like this is probably easier than I’m trying to make it right now.

There is a “DoOnce” node.

You can reset it but as long as you don’t it will do this exactly one time :wink:

That’s actually a perfect solution in this scenario. Thanks!
