How to make a circle tween like this?

Hey, I’m looking to make a circle tween like this.
I’m a little lost where to start with it, so some guidance would be helpful as ever

thank you in advanced!

Some time ago I found a video that would work for that, but it seems that the effect only works if the color of the bar is green

Try searching up top using the term “circular health bar gui”. I found a couple of posts about it.
