Variables

Ok, this is pretty sad but... I'm not sure how to put an icon state on a variable that has an icon... This is used when you click on a turf, so what i'm doing now is changing the icon state of the turf 
var/hair='hair.dmi'; icon_state="Short"
Any ideas?

Look up and use the icon() proc to create an /icon object with the wanted icon_state and/or direction (and it'd come in handy to look up the 'icon' entry as well as related ones too).

mob/var/hair
turf
    hair
        icon='hair.dmi'
        icon_state="Bald"
        Click()
            alert(usr,"Select a hair style.")
            var/select=input("","") in list("Spikey","Bald","Short")
            switch(select)
                if("Spikey")
                    src.icon_state="Spikey"
                    var/red = input("What color red","select") as num
                    var/blue = input("What color blue","select") as num
                    var/green = input("What color green","select") as num
                    var/hair=icon('hair.dmi',"Spikey")
                    hair+=rgb(red,green,blue)
                    usr.overlays+=hair
                    usr.hair=hair
                    src.icon=hair
                if("Bald")
                    src.icon_state="Bald"
                if("Short")
                    src.icon_state="Short"
                    var/red = input("What color red","select") as num
                    var/blue = input("What color blue","select") as num
                    var/green = input("What color green","select") as num
                    var/hair=icon('hair.dmi',"Short")
                    hair+=rgb(red,green,blue)
                    usr.overlays+=hair
                    usr.hair=hair
                    src.icon=hair
Yeah, so once I tried the icon procedure, it gives me this error: runtime error: <font color=red> type mismatch
proc name: Click (/turf/hair/Click)
usr: Speedro (/mob)
src: the hair (4,8,2) (/turf/hair)
call stack:
the hair (4,8,2) (/turf/hair): Click(the hair (4,8,2) (/turf/hair))</font color=red>

The problem is, i'm not too good at reading these and understanding so i'm kind of lost (which is very fustrating).

Perhaps this is what you're looking for?

mob
  var/icon/hair


and probably this is what you want to do...

   usr.hair = icon('hair.dmi', "Short")

Which line is it referring to?

Hmm? What do you mean? If you mean what i think you mean, you mean that when does the error occur? That's probably not what you mean - but it occurs after I finish putting in a number for red green and blue.

No, that still gives the same error.. :/

put this anywhere in the code, then the error will tell you which line of coding is breaking (press Ctrl+G to go to a specific line)

#define DEBUG

But that's just the thing, I know where the error is coming from already, I just need to know how to get the var to hold the icon along with the icon state. It works fine when I don't try to add an icon state to the variable, but I need one there.

if it were me i would make a obj with the icon and state you wish and then just have the var hold the obj/turf/mob...of course if there were tons of icons/states then this wont work lol.

and src.hair = icon('hair.dmi',"short") doesnt work?

Compile errors appear the same in debug mode, it just affects alerts at runtime. Also, you can just double-click on an error line in the error window to jump to that place in the code, rather then using CTRL-G manually.

Well, >_> I took the lazy quick way in my last post since you didn't specify the actual error line, but it's obviously the hair+=rgb(red,green,blue) line. Look up 'icon arithmetic' in the DM Reference. The method of using operators on icons is being phased out, and works on icon files, not /icon objects. That's why you get a type-mismatch error, since += may not be used with the '/icon object' type, only numbers, lists etc.
Use the icon.Blend() proc instead.
Also, you have a lot of repeating code over there in the switch() cases... just farm it out to outside the switch() so you have it once.

hair = Blend('hair.dmi',function=ICON_OVERLAY)


Umm, the blend procedure doesn't exsist??? >_>

I wish the reference would explain things in baby words, I don't understand the slightest thing it's saying >_>

Gah. You can at least look around before posting, there are countless posts on this.
