How to make an immutable Slider in Unity?

Question

Unity

In my game, the health bar is implemented using the Slider UI component, but I have one problem: the Fill in the Slider can be moved. Although in my code I wrote in FixedUpdate that: slider.value = hp; but you can still move it evenly, although it immediately returns to its place, but still, it does not look very good. Please tell me how to fix this?
Thanks in advance!

Answer 1

Don't use slider for this, that's all. A progress bar can be made from an Image - it has a Filled fill type.
If you really want a slider - then chop off everything that can catch a click there - remove the Raycast Target from all Image. If this does not help - a mega-crutch - put a transparent image on top, let it catch clicks.

I know it's late, but in order not to change, you need to disable the first checkbox
