this is probably a really noobish question but i can't take it anymore! i have to find out...
how do i make it so that things in my inventory appear marked by an icon instead of red words? can i make it so that objecta are in my inventory rather than stats that are totally different to the object they are meant to refer to?

I recommend reading the whole article and checking out other tutorials in BYONDscape (er, not sure if you're able to read it though)

Great, that works, now to equip. What do i do so that if i click a sword, for example, it would appear on the same spot as me, follow me wherever i went (so it looked like i was holding it) and no one else can pick it up when i'm holding it?

You want to look up on 'overlays'

usr.overlays+=image('X.dmi',"XX")
usr.overlays+=src.icon

oh yeah, overlay, how could i forget? except that Click() doesn't seem to work. can you edit this so that it works as i explained?
        if(statpanel("inventory"))
            if(wealth >= 0)
                var/obj/O = new()
                O.icon = 'gold.dmi'
                O.name = ""
                O.suffix = "£[wealth]"
                stat("", O)
            if(woodshield >= 1)
                var/obj/O = new()
                O.icon = 'wooden_shield.dmi'
                O.icon_state = "big"
                O.name = "x[woodshield]"
                O.suffix = "unequipped"
                stat("wooden shield", O)
            if(woodsword >= 1)
                var/obj/O = new()
                O.icon = 'wooden_sword.dmi'
                O.icon_state = "big"
                O.name = "x[woodsword]"
                O.suffix = "unequipped"
                stat("wooden sword", O)

Sorry, it's just that i've never tried anything involving Click() or this inventory images thing.

obj
   House
      verb
         Click()
            usr << "You are a clicker."
      icon = 'house.dmi'

Thats an example of a obj verb...I think...

Click() is a proc!!! Like New(), Del(), Login(), etc. 
obj/Apple
  Click()
    .....


Also, that's a horrible thing to do Adam (the new obj in statpanel) because stat panels are updated quite frequently... so you'll be creating a huge amount of useless object. My solution is you should make a predetermined list: 
mob/var/Statobj = newlist(/obj/health,/obj/shield)  // newlist is like list(new A,new B,new C) etc
And ofcourse, create those objects [though modify your coding to reflect the changes of equiption and stuff like that... I recommend having generalized procs, such as for money gain).

i know its a proc but where do i put it!? it's just...not...working!!! look.
obj
    wooden_sword
        icon = 'wooden_sword.dmi'
        icon_state = "big"
        Click()
            usr.overlays += image('wooden_sword.dmi')
            usr.overlays += src.icon
            icon_state = "small"

at least i'm going somewhere with this. but if i click it in my inventory, nothing happens, and if i click one thats on the map, it goes small but doesn't follow me.

            usr.overlays += image('wooden_sword.dmi')
            usr.overlays += src.icon


Did you even looked up overlays in the DM Reference? You are adding two overlay icons together, one which has an icon state and the other doesn't!

The problem may be you didn't enter the icon_state, assuming the icon file has no default state to change to if there's any mistake.

BTW, that positioning for Click() is correct and if I were you, I would add safety checks (such as if the item was in the inventory, one step away, etc).

......
so are you saying that something does have an icon state and shouldn't or something doesn't and should? and where in the DM guide is an overlay explanation?

In response to Adam357
Note I said DM Reference not DM Guide (Reference = F1 in DM).
usr.overlays+=image(src.icon,src.icon_state)
would be the best to place in for a generalized equipment system (and adding in other stuff like layer if applicable).

http://www.byond.com/docs/ref/info.html#/atom/var/overlays

As you may know, if an icon file has no default icon_state (the blank icon_state) and if you mistype an icon_state, it'll go to the default. If there's no default IS, it'll be blank... so always try to have a 'safety default' (Like a huge red X) to signify if something is wrong [f you have no default IS].

problem with theories:
obj
    wooden_sword
        Click()
                usr.overlays += image('wooden_sword.dmi')
                usr.overlays += image(src.icon, src.icon_state = "small")
                usr.woodsword -= 1
                usr << "click!"

when i do that (or close enough, trust me) it doesn't even say "click!" to me, so the problem is something to do with the Click(), not the overlays or the icon states.

should you not use "usr" here since its in a proc or is Click() an exception to that rule?

Anything that is directly called by (and limited only to) the client/player, such as: Click(), DblClick(), /verb can use 'usr' safely... things that are called by the program itself, such as Bump(), Move(), or anything that can be called indirectly and NOT limited to the client/player should avoid using 'usr'.

here's some links of interest:

I dislike using image() to add overlays. It tends to make your sprites stick to you...I prefer adding src itself directly to your overlays, like you would directly equip it to a var not make the var an icon or the like. But that's just me.

Thanks I've been looking for things to explain this to me, I understand why you shouldn't use usr but I've been wondering how not to use usr

Usr is only safely allowed in verbs, Click(), and DblClick()
