Health bar how to optimize?

Question

Unity

How to make a health bar so that it is optimized. I watched the lessons, but if there are a lot of objects with a strip of HP on the stage, then there will probably be a heavy load (I looked where they did it through the sliders)

Answer 1

In my game, I made a HP strip through a simple shader. Perhaps it is not so optimized, but still better than creating a canvas for each object.
I took it from here: https://habr.com/en/post/447716/
Another little tip. You can draw bars not all the time, but only when the enemy is damaged and, say, after 2 - 5 seconds turn off.
