how to fix

Every time i click on gain exp the exp bar vanish, poofs, disappear.

Can you share the project file?

how do i share it?

Upload the file to google drive, mega, dropbox or any other and share the link

it seemed like it has to do with the "Set width"

Run it on debug mode, you can select the bar after click on gainExp and see where is it, if its outside the layout.. or if its a size problem like width=0

Why are you changing the health bar value only when you gain XP? Would it be better to do that every tick? It might give you a better picture of what your XP bar is doing. The math looks right though...

After click the expBar width is = infinity on debug.. let me see why

OK so first of all.. its because the Player.nextLevel is = 0.

the problem is at the "Set Width" :v

ah well...i'll figure it out lol i just need to know how to set the exp bar width, i just thought the health bar would be same as exp bar

The problem is your math.

You are doing: Sprite Width * (Player.EXP/Player.nextLevel)

Sprite Width: 70.441

Player.EXP: 60

Player.nextLevel: 0

Do the math...

like klabundee said,

That is sort of correct. Your math is currently:

70.441*(Player.XP / Player.nextLevel)

substitute in values you get:

70.441 * (0 / 0 ) - Does Not Exist (DNE)

On clicking AddXP

70.441 * (60 / 0 ) - Creates infinity. Try it on a calculator.

Just select your player sprite and change nextLevel to 500 and LvL to 1

Here.

Don`t forget to chance player.Lvl to 1 and player.nextlevel to 500, also you need to change the EXP origin point to left instead of middle.
