Here's a simple little health bar that I spent far too long creating. It's a WIP, because it definitely still has some kinks I need to work out; and it could definitely be optimized a little better. For the most part though, it works pretty well and is highly customizable. There are a few limitations though, and the main one is that it can only be put on the left side of the screen. This is because the health bar is based around X position and going offscreen, and if it were to be put in the center of the screen, the offscreen part of health bar would be visible. I am working on a costume based health bar as well with even MORE customizability, so stay tuned for that. You can use this without credit, though credit is always appreciated. If you wanna use this, just put the sprite into your health bar and call it a day.
