how do i make it so if u can't affored something at a store it will not let u buy it? in my game it just says it and gives u the thing anyway. it also makes the money go into the negatives. If someone could help me i'd appriciate it.

thanks


P.S.- were can i find code to allow GM's to make a Clan and let other people join them by me making them part of it??

Use

if(usr.gold<=0)//if there gold is less then 0
usr<<"sorry too poor"
return

Remember change the gold var to your money var.

I beleive this should work. 
mob/var/cash = 100
NPC/Merchant
     parent_type = /mob
     proc/Buy()
          switch(alert(usr,"What would you like to buy?","What Item?","Sword","Shield","Pants"))
               if("Sword")
                    if(usr.cash < 50) goto CANNOT_BUY
                    else
                         usr.cash -= 50
                         new /Weapon/Sword (usr)
               if("Shield")
                    if(usr.cash < 60) goto CANNOT_BUY
                    else
                         usr.cash -= 60
                         new /Armour/Shield (usr)
               if("Pants")
                    if(usr.cash < 30) goto CANNOT_BUY
                    else
                         new /Armour/Pants (usr)
                         usr.cash -= 30
          usr << "Thank you for buying!"
          return
          CANNOT_BUY
          usr << "You do not have enough money for that!
PC/Player
     parent_type = /mob
     verb/Say(var/message = "" as text)
          world << "[src.key]: [message]"
          if(ckey(message) != "venderbuy") return
          for(var/NPC/Merchant/M in hearers()) break
               M.Buy()
Weapon/Sword
     parent_type = /obj
Armour
     parent_type = /obj
     Shield
     Pants

all i really need is the code so if the amount of money is less then the cost of the object then it won't let u have it. here is my Bed code

turf
Inn_Bed
icon = 'bed.dmi'
verb
Sleep()
set src in oview(1)
switch(input("U look a little tired. Do u want to sleep for 100 dollers???","???")in list("Yes","No"))
if("Yes")
usr.Health = usr.MaxHealth
usr.gold -= 100
if("No")
usr<<"u don't feel like sleeping"
..()

i have it working it just puts u in the negatives if u have less then 100 gold

ok it finally didn't pop up w/ errors but now when i sleep it takes my gold still even though i only had 10 gold making it -90. it gave me the health too but now i'm in the negatives w/ money.
Feb 25 2002, 2:34 pm
In response to Alienman22774
Take out the && usr.gold < 99
THen add another if under it that says

if(usr.gold < 99)
return

so in the end what should it look like i got 9 errors they were all verbs.dm:129: Inconsistent indentation. but one wasverbs.dm:130:warning: empty 'else' clause.

In response to Alienman22774
Then you need to fix your indentation :o)

There you go also I suggest you study DM more than what you have so you will be more independent than interdependent.

The other error means you have an 'else' statement without an 'if' statement.

Just as a side note, this is rather drawn out. If the users gold is under 99, it won't matter if its under 0. One if() statement removed.

And if it gets to if(usr.gold>=100) that means usr.gold is over 99 because it didnt exit the verb, so that if() statement is useless as well.

Too many useless if() statements can eventually lag up a game.

Alathon, effeciency is key.

Mmm...wonderful compactness.
