Property Test For Travel Direction?

[tommygdawg]

Hey all,

I feel like this should be super simple, but I can't quite figure it out. I have particles shooting up and being affected by a force. When they start to fall back towards the ground, I'd like them to pass a property test and be deleted. Is there a way to do this?

Thank you!

Test if velocity Z is less than the desired downward magnitude.
