Lifebar questions

Gamepenciler

Hello guys, I have a question about lifebars.
I want to have a character that has life that levels up
like:
Lv: 1 = 50 HP
Lv: 2 = 75 HP
Lv: 3 = 100 HP

But i want to constrain the value to a fixed with of 100 pixels
I can't find any tutorial that relates to my question. The one I found was when the life changes the width increase.
How can it should stay 100 pixels even if the life value changes?

This demo I made for someone else allows you to easily change the max value of the life bar without the bar itself increasing in size.

If you have 100 pixels then I would translate your HP to percentage so that the health bar will always display the correct percentage of health.

Ok, how do i convert it into percentage?

To clarify, are you wanting the HP bar to start at 100 pixels no matter the HP value and go down towards zero pixels as HP decreases? As @Summation suggested you'd constrain the width to game.HPremaining/game.HP*100.

Something like...

game.currentHP/game.maxHP

This will give you the percent, right?
For example, if my max is 100 and my current is 25, I have 25%.
The thing is... 25/100=0.25

So, the formula needs one modification.
If you multiply the result times 100...

(game.currentHP/game.maxHP) times 100
(25/100) times 100=25

If you have a health bar with 100 pixels and you display 25, you are displaying 25%.

You may also consider rounding the result either up or down to the next whole number just to make sure (but this probably isn't necessary...?)

Resposting the demo for anyone who wants it, as accepting an answer hides attached files. ( @ForumNinja anything you can do about that?) Glad it could help though!

Thanks guys: @Armelline @Summation @tatiang i think all of you have the same logic.. I will try this out soon...
