Making a new health bar

[Asweez]

I want to make a new health bar that is a bar instead of hearts. I was wondering if/how I could make the health go down in smaller increments(than half hearts) because my sword does varying damage and it isn't always in half heart increments.

Hi

Here's my suggestion - use forge events (just ask if you need to know specifics) to cancel the health bar, render your own based upon how many hearts you have. As for your sword's custom damage, listen for when the sword is attacking the entity and then cause custom damage there (or change the sword's damage [easier IMO]). Hope that helps!

You won't need any events for the sword damage - Minecraft already tracks health down to far finer fractions than is shown on the health bar.

 

I recommend you start with the Gui Overlay tutorial - though dated, it is still very relevant and will get you 85% of the way there.

How so?

What do you mean, how so? The player's health is a floating point number, so the player can actually receive 0.1 damage and such, not just 1/2 heart (1.0 damage) or 1 full heart (2.0 damage). But Minecraft only DISPLAYS health as if it were either full or half.

 

Display of information does not always equate to the actual form of that information.

But I did 10.88 damage with my sword and the console printed out a whole number when I used entity#getHealth

Most damage in Minecraft is either 1.0 or 2.0 or some other whole number.

Clearly, those are not whole numbers.
