Some maths help :D

[.:HyPeX:.]

Hey guys, who can help me work this thingy out?

I want to display health(0-100) to R(0-255) but inverted, (like 100 = 0)

Basically i did this, but idk how to invert it.

  
local health = getElementHealth(player) 
local health = math.floor((health)/1) 
local health = math.ceil(health) 
local health = health / 100 
local health = health * 255 
  

Ths makes that at 100% health, the R will be 255, how can i make it the other way arround?

i don 't really get what you're trying to do.

Just make the screen turn red when you're on low health

Try:

local maxRedCol = 255 
local health = getElementHealth(player) 
local red = maxRedCol - ((health*255) /100) 
red = math.ceil(red) 

But you still have to adjust with getPedStat(thePlayer, 24), if player's health returns a value greater than 100.

it should never get greater than 100, (my script stops it at 99.9)

Well, if you've done a system for that (as you said), then ok.

But keep in mind, if the max health stat is more than 569, then player's max health will be greater than 100%.

I made it quickly based on what is put on the MTA Wiki. You can change it however you wish. I'm just showing you a example you could use to build your own.

if you read carefully, i wanted the maths part, not the script imo. (even the topic name says so)
