How do I make an oxygen tank?

So how do i make an game overlay that says oxygen and every second it goes down? lets say the "oxygen " is energy. I want it so if you have 20 energy, the game overlay says oxygen level : 20?

Movement meter? It has a built-in tick and auto removes an item. :slight_smile:

thanks I’ll try that.

So you need oxygen to move, that kinda makes sense. Maybe.

If you want it to always go down, attach an item granter with -1 every second with a repeater or trigger loop.

Use block code in the overlay. It should receive on a channel every time the oxygen updates. Use set text: property. You would have to use a pseudo tracking system.

what is that?

Even easier, it wont say oxygen, per say, but you can just use a game overlay that is set to track item, item is energy.
