Simply look at the Fill Area gameobject, you will see that there is a right padding in the RectTransform ...

This is the correct answer. When you remove the slider handle you have to adjust the fill padding to account for it.

"Padding area" isn't labeled in the Unity UI. The values next to the pivot/anchor widget are the padding. For a normal bar, set the value for Left and Right to the same as the lower value between the two.

$$anonymous$$ine was 5 and 15. Setting both to 5 gave the expected result. Setting 15 to 0 overstretched it, making the bar bigger only while full - which could be a neat effect on it's own, if you want it.

I dont think you should be using slider for a health, why not simply change the width of the rect ransform considering the health amount?

1) Why reinvent the wheel, when Slider already does most of the work for you? 2) Because when you google "how to make a health bar in Unity", about 3,293,984 results come up saying "Use a slider bar".

if you dont care about loading times, especially on weak devices, such as mobile then go ahead. And the wheel thing you are talking about, this approach could be summarized as using nuclear reactor to turn single cart wheel

i dont think a slider will break your game, i use it all the time for my games, it has like 0 impact to performance.

@YoungDeveloper Yes using a rect transform will have less performance head on a mobile device but I don't think it would be that large. It depends on what sort of game you are making.
