How do you portray the percentage of a var, such as [health]/[max_health].
Dec 25 2009, 6:49 pm
It's all math:
mob
    var/health       = 1
    var/max_health   = 10
    var/tmp/convert  = health/max_health*100
    alert("[convert]% HP left!")


Hope that helped!

P.S.
This is the guy that just IMed you asking if you needed coding help. xD

This just displays the [health] var.

ok this is how you calculate a percentage.

if your character has 100 Health points when they have full HP. then that means their Max Health is 100.

divide current health by max health and multiply that by 100.

it will give you the current percentage of your characters health.

this is what it looks like in code

var/currentHpPerc=(Hp/MaxHp)*100

src << " You have [currentHpPerc] health remaining."

the key part is the parenthese around HP and MaxHP

If your problem still isn't solved, here's a basic code =P

mob
    var
        HP=100
        MaxHP=100
        
    Stat()
        var/HP_Percent=round(src.HP*100/src.MaxHP)
        stat("Health: [HP]/[MaxHP] - [HP_Percent]%")
        ..()

No, the "key" is not the parentheses. The result is the same regardless of those parentheses. Perhaps you need to read up on your order of operations.

Please take note that the compiler cannot calculate expressions in a variable definition like that. To do so would need to be placed inside a New() override.
mob/var
    hp = 1
    m_hp = 10
    percent = hp/m_hp*100
//BAD!!

mob
    var
        hp = 1
        m_hp = 10
        percent = 100 //why not start with 100% by default?
    New()
        ..()
        src.percent = src.hp/src.m_hp*100
//GOOD!!

yep your right perhaps i do.

just wondering why everyone on this board is so...
rude.

is that a habit of people who code or program?
to just assume someone is a newb because they don't know as much as you or forget little things here and there?

and it would be a key point if he didn't have a multiplier and divider on the same line. the parentheses force which one you want done first. its kind of like insurance :P

Coders assume everybody is stupid.
Just like pixel artists assume everything they do is worth $1mil

Its kind of because they are god-likes when coding, do w/e they please and make things happens the way they want

And spunky girls, you don't need to make it a var just to display it

mob/Login() //Can be used anywhere tho, but since this is an example..
    //do your things
    usr<<"[(usr.Health/usr.MHealth)*100]" //Parentesis make it look nice, even tho Spunky Girl doesnt like it
    //if this doesnt work, something is wrong with the way you trying it


Talk to me over msn if you need further help (you already have it ;o)

He never said how he planned to use it. I'm not psychic. I provided the most universal method I could think of. Which in this case, is a variable.

<sarcasm>
We just love to make lesser beings feel like idiots when we show them up with our obvious superior intellect.

Your less-than-obvious prejudice against programmers and pixel artists couldn't be more correct.
