Code:
mob
    var/MHP = 100
    var/HP = 100
    Login()
        ..()
        UpdateHealth()
    proc
        UpdateHealth()
            var/objx = 20
            var/objy = 20
            for(var/L in "Health: [HP]")
                var/obj/font_letter/f = new
                world << f
                f.icon_state = "[L]"
                f.screen_loc = "[objx],[objy]"
                world << f.icon_state
                world << f
                client.screen+=f
                objx++
    


obj
    font_letter
        icon = 'Arial7pt.dmi'


Problem description:
Basically, i am trying to create a loop with a string. What i am trying is to try to get the variable L to = each letter in that string and assign it to a new font_letter and change it icon_state to the correct letter.
I recieve no errors but it doesnt appear.

Unless you've got a 20x20 screen, I don't think that it's going to pop up.

What size is my screen then?

By default it's 15x15 IIRC. (world.view = 7)

EDIT: I'd also like to note that if the map is like 10x10, you will see the whole thing

Okay, I looked it up at the view is actually 11x11 default. Sorry (world.view = 5)

<s>Also, I wanted to note that your code is going to stack all of the letters on top of each other. </s> Nevermind. Didn't see last line. But it does make it so that you have 1 letter per tile

Found it. Your for() loop isn't working. Try using copytext instead.

Can i have an example for that please?

Copytext returns a text string. Since you to do this proc for each letter, I'd suggest doing something like this.

1. Define the length of the text string
2. Define a generic variable to be 0
3. Copytext (and add) each letter individually

var/X = copytext("Hello", X, X + 1)

This will return the letter you want it to return

Note: Make sure you add 1 to that generic variable each time so that you progress through the text string.

And what if i have a variable in it/ Would it still right? And im unsure how to do the loop for it.

A variable is fine.

var/X = copytext("[src.Hp]",1,2)


Works just as well as anything else.

As for the loop, you could have a while(X < textlength) (X being the number of the letter you are copying)

You can use the length() proc to get the length of the string.

To loop through every character in a string I'd do the following:

var/string = "Some string with stuff"
var/char
for (var/i = 1, i <= length(string), ++i)
    char = copytext(string, i, i + 1)
    world << "character [i] is [char]"


EDIT: Better yet, make a variable to store the length

var/string = "Some string with stuff"
var/stringlen = length(string)
var/char
for (var/i = 1, i <= stringlen, ++i)
    char = copytext(string, i, i + 1)
    world << "character [i] is [char]"

I should mention that screen objects will still show up, even if they are outside of the viewing screen. Read the last 2 paragraphs of this.

Complexrobot example helped a lot. Now i gotta space them out correctly... Any tips on how to do this?

Instead of using tiles, use pixel location.

In response to Lugia319
Can i have an example of pixel location just to make it clearer?
Aug 12 2011, 2:23 am
In response to PCGeek
 
obj
  Letter
    pixel_x = 10
    pixel_y = 10


If you created a new letter, it would appear 10 pixels to the right and 10 pixels from the bottom.
