Would it be possible to reverse a value?

Hey again devs,
i have a quick question as it may help me in what i’m trying to achieve here.

Basically let’s say you have some type of value that can increase and decrease at a minimum of 0 and 1.

Now if you would set for example a part’s Transparency to this value it would be transparent at 1 and visible at 0.

Would it be possible to reverse this math? What i mean with reverse is if the value is at 0 the part would be transparent and if its at 1 then it would be visible.

I’m not talking about if statements by the way. As i would like the number to also go in between 0 and 1.

Any help would be appreciated.

I got an idea. What if you do 1 - Transparency = Reversed transparency. Example 1: 1 - 0.4 = 0.6.
Example 2: 1 - 0 = 1

local transparency = 0;

transparency = transparency == 0 and 1 or 0 -- switches between 0-1 depending on the current value

i’ll try this out, give me a second and ill be back to you

Not exactly what i am trying to achieve here, the value of transparency could also change into decimals (aka between 1 or 0).

#6

Would you like it to always move between from 0 to 1 OR 1 to 0?

From 0 to 1, to be more specific i am trying to match the PlaybackLoudness of a sound to the TextTransparency. I just realized that the PlaybackLoudness will actually end up as 0, so the TextTransparency would just be visible.

You can change the 1 to the max amount that the value can hold. I don’t know if this works if the value uses negative numbers tho.

Read the post above, i made a mistake by making this post as i already got it working. Sorry about that

#11

Well you could just then do percentage counting with playbackLoudness / maxPlaybackLoudness which returns value between 0-1.

It’s fine! Good luck with your project.

I am indeed doing that, it just looked weird at first so i thought there was something going wrong.

I’ll give this post the Solution as it basically is the way i’m doing it. Thanks for all!

Yeah it probably will look weird at first, since you can’t really get the maximum value of PlaybackLoudness, so you have to move it up slowly.

What if, lets say I’m trying to make an ammo counter and as you loose ammo the image becomes more transparent/invisible.

I have a max ammo count and a current ammo count

ammoIcon.ImageTransparency =  currentAmmo/maxAmmo

but this makes the image transparent at the start and makes it less transparent. I’m aware as to why but I need to know how to make it do the opposite.

#18

You substract the percentage from 1, which will make it reverse.

1 - (currentAmmo / maxAmmo)

Oh my gosh, I feel so stupid now.

Such a simple answer!

Thank you for the help! :slight_smile:
