hi i was reading a tutorial on byond

here is how to get in the tutorial
developer/turtorials/zbt(Zilal's beginner tutorial)



now i have been fallowing along and i came up to this problem this is my code:












mob
verb
say(msg as text)
world << "[usr]:[msg]"




obj
gold
icon = 'gold.dmi'
var
amount
verb
get()
set src in view(1)
usr << "you picked up [amount] gold"
usr.wealth += amount
del(src)


mob
icon = 'person.dmi'
Login()
icon_state = gender
..()
proc
DeathCheck()
if (HP <= 0)
world << "[src] dies!"
Del()

mob
del()
var/obj/gold/G = new(loc)
G.amount = rand(1,100)
..()






bug //new protoytipe
icon = 'bug.dmi' //override the parants icon,which was person.dmi



mob
var
HP = 30 //declares a new variable called HP, with a value of 30


mob
verb
attack(mob/M as mob in oview(1)) //attack the mob 1 tile from you
if (M.HP <= 0)
usr << "[M] is alrady dead"
else //otherwise....
usr << "you attacker [M]" //send this masseg to the usr
oview() << "[usr] attacks [M]"//send the massage to everyone ealse
var/damage = rand(1,10) //asign and random number to a new variable
world << "[damage]:damage!"//tell the damage to the world
M.HP -= damage //take away the damage from M
M.DeathCheck() //Check for dead with a proc




turf
grass //defines a "grass" prototype, which is a kind of turf...
icon = 'grass.dmi' //and has an icon named 'grass.dmi'. In single quotes!


world //we set one of our world's characteristics:
turf = /turf/grass //its default turf is the grass turf.
