Text "Heatlh bar"

[unlimit]

Lets say I wanted a healthbar made completely out of text, and for every 10% it would add another letter, it doesn't have to be different, just one like this:

[++++++++++] 100% [+] 10% [+++] 30%

What is the founding principle of doing this? How would I be able to make a letter "repeat" with the proper variable?

Sounds like the following will help give you an idea.

http://www.wowpedia.org/API_strrep

eg.
string.rep(s, n)

health.rep("x",maxhealth/curhealth)

or something somewhat similar

Here's some code that would return the string you proposed.

function GetHealthTextBar(unit,base,fmt,char)
    local pcnt=UnitHealth(unit)/UnitHealthMax(unit);
    return (fmt or "[%s] %.0f%%"):format((char or "="):rep(math.floor(pcnt*(base or 10))),pcnt*100);
end

unit is required. base, format, and char are optional.

• unit - UnitID of target to query health of.
• base - Width of the status bar in chars when full.
  default: 10
• format - Format string in which the status bar is constructed.
  The first argument is a repeated string consisting of the bar itself, the second is a float value representing the health percentage.
  default: "[%s] %.0f%%"
• char - String to be repeated that makes up the text bar.
  default: "="

You know, honestly, that little amount you just wrote actually taught me a LOT of what I've been wondering about recently?

Thanks SOO much!

I suggest that you always have 10 +, Sth like

[++++++++++]

That way the bar does not jump all the time. But not sure if applying the text color to the format string of phantom is that easy to add. Here are the functions that may be needed.

--calc hex color from rgb
  local function RGBPercToHex(r, g, b)
    r = r <= 1 and r >= 0 and r or 0
    g = g <= 1 and g >= 0 and g or 0
    b = b <= 1 and b >= 0 and b or 0
    return string.format("%02x%02x%02x", r*255, g*255, b*255)
  end
 
  --green col
  "|c00"..RGBPercToHex(0,1,0).."+|r"
  --gray col
  "|c00"..RGBPercToHex(0.3,0.3,0.3).."+|r"

I was actually just about to ask about that today!

Reading my mind Zork!

Thanks a lot!

Hellz yeah

[♥♥♥♥♥♥♥♥]

[unlimit]

This is what I came up with (this is in an openrdx script, so all functions are confined to that script only besides "text").

function RGBPercToHex(r, g, b)
    r = r <= 1 and r >= 0 and r or 0
    g = g <= 1 and g >= 0 and g or 0
    b = b <= 1 and b >= 0 and b or 0
    return string.format("%02x%02x%02x", r*255, g*255, b*255)
end
function GetPlayerHealthBar()
    local cpercent = unit:FracHealth() * 100;
    local mpercent = unit:MissingHealth() / unit:MaxHealth() * 100 + 10
    if cpercent <= 99 then
        return ("[|c00"..RGBPercToHex(0,1,0).."%s|r|c00"..RGBPercToHex(0.3,0.3,0.3).."%s|r] %.0f%%"):format(("="):rep(math.floor(cpercent*(0.1))),("="):rep(math.floor(mpercent*(0.1))),cpercent);
    else
        return ("[%s] %.0f%%"):format(("="):rep(math.floor(cpercent*(0.1))),cpercent);
    end
end
text = GetPlayerHealthBar();

Any suggestions or improvements anyone can see off-the-bat in that?

In action (muwahhaahhaha):

I'm too colorblind for that idea...

Isn't OUF_Hank along the lines of what you're looking for?

I did something similar almost a year ago in ouf, I can post the (terrible) code if you want.

I like it a lot, Buddie! You should upload it as an oUF ;P I'm sure people would love that, and I would personally love to see your code!

I'm just making it for my own sick boredom, not really looking for other peoples though, Pablo242!

I would suggest, if a color code isn't variable, you shouldn't waste CPU time on a function call for it.

This would turn (0,1,0) to "|cff00ff00" and (0.3,0.3,0.3) to about "|cff4d4d4d".

function GetHealthTextBar(unit,base,fmt,char)
    local pcnt=UnitHealth(unit)/UnitHealthMax(unit);
    return (fmt or "[%s] %3$.0f%%"):format(
        (char or "="):rep(math.floor(pcnt*(base or 10)))
        ,(char or "="):rep(math.ceil((1-pcnt)*(base or 10)))
        ,pcnt*100
    );
end

This is a modified version so you could send it a colored format string to achieve the same effect.

GetHealthTextBar(unit,10,"[|cff00ff00%s|cff4d4d4d%s|r] %.0f%%","=");

The default format string changed to skip the second string argument, notice the added "3$" after the format escape char "%". This tells string.format() to select the 3rd argument directly, which allows the default to retain the old function.

Man, you people blow my mind sometimes. I hardly know what I'm doing, wish I could say I knew how to do it like you guys

[SDPhantom]

I was programming since I was a kid. Easily 20 years of experience there. The last 8 years was spent writing in Lua. And yes, that includes pre-WoW experience with Lua.

I don't think I could be bothered with cleaning it up, adding more features, maintaining it etc. It never worked how I wanted it to so I gave up.
