Well, I have been putting together an RPG using Byond, and I was using the ZBT guide for RPG's (http://zilal.byondhome.com/tutorials/zbt.html) and I have just started to add the combat system.

I have entered the code as below. This is my first time programming so I don't have much experience.


-------------------------------------
world

mob = /mob/player


mob
player
icon = 'player.dmi'
var
HP = 30 //define a new variable called HP, with a value of 30

Login()
icon_state = gender //when a player logs in, make their icon's state
..() //the gender of their key. Then call the parent!

proc
DeathCheck() //checks to see if an attack is deadly
if (HP <= 0) //if the defender's HP is low enough...
world << "[src] dies!" //do the death messaging

verb
attack(mob/M as mob in oview(1)) //attack a mob within 1 tile of you
usr << "You attack [M]!" //send this message to the usr
oview() << "[usr] attacks [M]!" //send this message to everybody else
var/damage = rand(1,10) //assign a random # 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 death with a proc

enemy
icon = 'soldier.dmi'

bug //new prototype
icon = 'bug.dmi' //override the parent's icon, which was 'person.dmi'
--------------------------------------------


However, when I try to 'run' the game, i recieve these errors:

fantasy.dm:30:error:M.HP:undefined var
fantasy.dm:31:error:M.DeathCheck:undefined proc


I believe that this is because the program does not know what 'M' means. However, I do not know how to resolve this problem.


Any advice on how to solve it?
