Hmmm… This one is tricky.
As of right now, I don’t believe there is anyway to directly track health as it goes down. However, some things that could possibly work would be Pseudo Health and maybe using properties.
Now, I would have to assume that your game is some sort of PVP or Battle game, where players fight each other or take damage in various ways. For this, I’m not quite sure if damage from other player’s gadgets or other things[1] can be tracked right now.
So, I’d recommend you take a look at these guides and see if they could possibly help:
