Code:
                if("Sell")
                    var/obj/o=input("What do you wish to sell?",src) as obj in null|usr
                    if(!o){usr<<"<font color =green><b>[src]:</font></b><font color=red><b> Stop waisting my time!</font></b>";return}

                    var/amountof=input("How much of [o] would you like to sell?") as null|num
                    if(amountof<src.amountof)
                        usr<<"Don't be trying to rip me off!"
                    else                    
                        switch(alert("I'll give you [o.value*amountof] gold for [amountof] [o]. Sell?",src,"Yes","No"))
                            if("Yes")
                                usr.Gold+=o.value*amountof
                                del(src)
                                usr<<"<b>You sold [amountof] [o] for [o.value*amountof] gold</b>"
                                usr<<"<font color=green><b>[src]:</font></b> Thank you." 
                            if("No")
                                usr<<"<font color =green><b>[src]:</font></b><font color=red><b> Stop waisting my time!</font></b>"


Problem description:
just says NPCs.dm:44:error:src.amountof:undefined var

i don't know how its undefined, or how to define it.

if the src is a mob:

mob
    var
        amountof = [what ever you want]


If the src is a obj or what ever, replace mob with the type.

In response to Y2kEric
Yes, you just set amountof as a var. If src is an obj it has to be an obj/var or if its a mob it must be a mob/var.
Those 2 variables must be assigned outside the sell code.

ok thx you very much, but:
del(src)

what would i change this code to so that it would delete the right amount of obj, and the right obj from the players inventory. Right now it deletes the shopkeeper. The code for my sell is in my first post. but here it is again.
                if("Sell")
                    var/obj/o=input("What do you wish to sell?",src) as obj in null|usr
                    if(!o){usr<<"<font color =green><b>[src]:</font></b><font color=red><b> Stop waisting my time!</font></b>";return}

                    var/amountof=input("How much of [o] would you like to sell?") as null|num
                    if(amountof<src.amountof)
                        usr<<"Don't be trying to rip me off!"
                    else
                        switch(alert("I'll give you [o.value*amountof] gold for [amountof] [o]. Sell?",src,"Yes","No"))
                            if("Yes")
                                usr.Gold+=o.value*amountof
                                del(src) // Or del(o), depends what system you want.
                                usr<<"<b>You sold [amountof] [o] for [o.value*amountof] gold</b>"
                                usr<<"<font color=green><b>[src]:</font></b> Thank you." // Quicky mart!
                            if("No")
                                usr<<"<font color =green><b>[src]:</font></b><font color=red><b> Stop waisting my time!</font></b>"

Shouldn't be src... Should be o.

var/atom/t=new o.type
for(amountof,amountof>0,amountof--)
    for(var/obj/O in usr.contents)
        if(istype(O,t.type))
            del(O)


I made atom/t because I am pretty sure that if I made it check to see if O was o.type, then it might have deleted o and then you would probably get a runtime. However, that should work.

no clue, this is my first game, and my first time coding one, if you could tell me how and what it looks like i would greatly appreciate it
Jun 30 2006, 3:25 pm
In response to FriesOfDoom
 
obj/var/value
or it mob/? your assigning the varible to an object so it should be the first one ^

In response to A.T.H.K
I've notice this is incorrect:

var/obj/o=input("What do you wish to sell?",src) as obj in null|usr


Correct way:

var/obj/o = input(usr,"What do you wish to sell?","Sell Item") as null|anything in usr.contents // Or it could be usr
