Trying to create a circular progress bar for a game I'm making

So what I’m trying to do is that as part of my game, when the player attacks enemies their Limit bar fills up and once it reaches the end, it’ll fill one of the dots. I have an example of this in the diagram below which also shows how the bar should bar, basically in a circular motion. Starts from one end then circular fills to the other:

(Apologies for the awful diagram, best I can do).

Anyways I was wondering how a blueprint of it could be made as I’ll be using an image of the limit bar itself as seen below:

Help would be appreciated, thank you. Also sorry if its a little confusing, first time poster.

You need custom material.
